ABSTRACT

A new Mediferranean species of the genus Alvania (Rissoidae, Rissooidea) is described:

Alvania aliceae spec. nov. Ai! known specimens come from the type iocality, Lampedusa

Is. It is compared with the most similar congeners: Alvania subcrenulata (Bucquoy,

Dautzenberg & Dollfus , 1 884), Alvania amatii Oliverio, 1986, Alvania nestaresi Oliverio

& Amati, 1 990 and Alvania baleárica Oliver & Templado, 2009. Additionally, a lecto-

type of Rissoa bicingulata G. Seguenza, 1 876 is hereby designated to stabilize its use.

RESUMEN

Se describe una nueva especie Mediterránea del género Alvania (Rissoidae, Rissooidea):

Alvania aliceae spec. nov. Todos los ejemplares conocidos provienen de la localidad tipo,

Lampedusa. Se compara con las especies congenéricas más similares: Alvania subcrenu¬

lata (Bucquoy, Dautzenberg y Dollfus, 1884), Alvania amatii Oliverio, 1986, Alvania nes¬

taresi Oliverio y Amati, 1 990 y Alvania baleárico Oliver y Templado, 2009. Además, se

designa un lectótipo de Rissoa bicingulata G. Seguenza, 1 876 para estabilizar su uso.

INTROD U CTION

The genus Alvania s.s. Risso, 1826

has particularly radiated in the Mediter-

ranean Sea, with over 70 species

(CLEMAM database: Gofas & Le

Renard 2014; WoRMS database: Gofas,

2014) and ineludes several species-com-

plexes (e.g. Alvania linéala Risso, 1826,

Alvania scabra (Philippi, 1844) and

Alvania subcrenulata (Bucquoy, Dautzen¬

berg & Dollfus, 1884), with wide geo-

graphic ranges and non-planktotrophic

development A population of the

Alvania subcrenulata- complex from

Lampedusa Island (southern Mediter-

ranean Sea) proved morphologically

distinct from all other known members

and is here described as new ( Alvania

aliceae spec. nov.), and compared with

the most similar known species from the

Mediterranean Sea.

2.80 (2.65) mm, width 1.30-1.60 (1.60)

mm, solid, ovate-conical.

Protoconch (Fig. 2, B-C) paucispiral,

with moderately twisted nucleus, con-

sisting of 1.25-1.30 (1.25) whorls, 0.30-

0.35 (0.30) mm high; diameter of

nucleus (d) 0.10-0.12 (0.12) mm, diame¬

starting after the metamorphosis; cord I

starting as a keel after 2 whorl, rapidly

yet gradualiy turníng into a cord; cord

III appearing at 2-4 whorls (Table I).

Rounded and elevated tubercles formed

at the intersection of ribs and cords,

somewhat spínulose in fresh specimens;

interspaces square ín the first whorls,

rectangular in the last one. Microsculp-

ture absent, except for growth lines (Fig.

2, D). Umbilical chink absent. Aperture

smaíl, 0.95-1.20 (1.1) mm high, ovate

rounded, thickened by a strong extemal

varix and intemally crossed by seven (7)

elongated teeth. Colour white, with

light brown spiral bands in particularly

fresh specimens. Operculum and soft

parts unknown.

Distribution: So far known only from

the type locality in Lampedusa Island.

The bioclastic sand where the shells

were found, was sampled in the inter-

matte of a Posidonia oceánica meadow

and it can be hypothesized that it lives

in that habitat. A. suhcrenulata (Bucquoy,

Dautzenberg & Dollfus,, 1884), which

elsewhere occurs in deeper habitats

(Templado ín Oliverio & Amati, 1990;

Gofas, Moreno & Salas, 2011; Conti &

Rossini, 1985; Bogi, Coppini &

Margelli, 1983) has been collected ín

the same samples. However, A. sub-

crenulata is considered as having a wide

bathymetric range (from intertidal

down to 40/45 m: Scaperotta, Bar-

tolini & Bogi, 2012).

For the distribution of Acinus bicin-

gulatus in the sense of L. Seguenza

(1903), see Remarks.

Remarks: The species of the Aivania

subcrenulata-complex: Aivania subcrenu-

lata (Bucquoy, Dautzenberg & Dollfus,

1884), Aivania amatii Oliverio, 1986,

Aivania nestaresi Oliverio & Amati, 1990,

Aivania baleárica Oliver & Templado,

2009 and Aivania aliceae show a teleo-

conch spiral sculpture starting with two

equidistant cords (II and IV), to which

subsequently two intermedíate cords

are added (I and III), and a total of 8-9

spiral cords are visible on the entire

body-whorl. The additional cords start

in different ways in the various species.

In Aivania nestaresi cord I is first formed,

followed by III. In Aivania subcrenulata

and in Aivania amatii cord III is first

are formed almost simultaneously. In

Alvania baleárica cord III ís first formed

Alvania nestaresi (Fig. 5, A) (Oliverio

180, 3 unnumbered figs.; Scaperrotta,

Bartolini & Bogi, 2012: 51, 5 unnum¬

bered figs.) differs from Alvania aliceae in

the more robust and inflated shell, with a

hígher aperture (h. 1.45 mm v. h. 1.20 mm

in Alvania aliceae). The tubercles at the

intersection of axial and spiral sculptures

are broader and less evident, with more

axials on the last whorl (14-19 v. 13-15 in

Alvania aliceae ); títere are always 4 spirals

above the aperture, equidistant and of

similar strength, v. the 3-4 of Alvania

aliceae (Table I). The protoconch of

Alvania nestaresi is lower (h. 0.25-0.30 mm

v. h. 0.30-0.35 mm ín Alvania aliceae ),

wider (max diameter 0.32-0.37 mm v.

0.35-0.40 mm), and has 6 spiral cordlets

(v. 6-7 ín Alvania aliceae ), whieh tend to

disaggregate in the last 0.25 whorls (Table

II). The colour is always whitish or with

brown spiral bands. A. nestaresi lives ín

the cavities of the calcareous alga Meso-

phyllum alternans , in the Posidonia oceánica

meadows of Almería (Gofas, Moreno &

Salas, 2011; Oliverio & Amati, 1990:88).

tolini & Bogi, 2012: 42, 5 unnumbered

figs.) differs from Alvania aliceae in the

more cylindrical outline, with a propor-

tionally higher aperture, and a less

marked sculpture (Table I). The proto¬

conch is on average shorter (1-1.3 whorls

v. 1.25-1.30 in A. aliceae), with 4-5 spiral

cordlets v. 6-7 in A . aliceae (Table II).

Alvania subcrenulata (Fig. 3, A-D and

Fig. 4, A-B) (Oliverio & Amati, 1990: 85,

87, figs. 2, 4, 8; Oliver & Templado,

Salas, 2011:180, 2 unnumbered figs.;

Scaperrotta, Bartolini & Bogi, 2012:

56, 5 unnumbered figs.) differs from

Alvania aliceae in the broader and more

regularly oval outline, with a higher

aperture (h. 1.20-1.45 mm v. h. 0.95-1.20

mm in Alvania aliceae ). The sculpture is

less 'echinate' and denser (Table I). The

protoconch of A. subcrenulata has a

spiral keel running just beneath the

suture, starting after the nucleus and

ending a little before the

protoconch/ teleoconch boundary, and a

sculpture of sparse granules (Table II).

Alvania baleárica (Fig. 5, B-C) (Oliver

& Templado, 2009:58, figs. 1-7, 28)

differs from Alvania aliceae in the more

convex whorls with a turriculated

outline (Table I) and in the different

apical sculpture (Table II).

lata G. Seguenza, 1876, actually misiden-

tified it and described (as Acinus bicin¬

gulatus) a species of the A. subcrenulata-

complex, one of the several mistakes

made by L. Seguenza (1903) (unpub-

lished observations). Regardless of

whether Acinus bicingulatus L.

Seguenza, 1903 (Fig. 4, C) is considered

as a mere misidentification with no

nomenclatura! valué, or as an introduc-

tion of a new taxon, Alvania bicingulata

(L. Seguenza, 1903) would be a júnior

secondary homonym of Alvania bicingu¬

lata (G. Seguenza, 1876) and cannot be

the valid ñame of any species. The

species dealt with by L. Seguenza

(1903) is very similar to A. aliceae , in par¬

ticular with its spinose tubercles at the

intersection of the spiral and axial sculp-

ture. However, according to the only

available illustration (L. Seguenza,

1903: 64[12] pL XI [I], fig. 9) and based

on the relative strength of the teleo-

conch spirals in the original figure, it

seems that the II and III spirals are first

formed (and not the II and IV as in the

other species of the complex, including

A. aliceae).

Alvania bicingulata (G. Seguenza, 1876)

is a Pliocene species, likely extinct, of the

A. dictyophora-complex (Palazzi &

Villari, 2001: 14,15, 36-37, figs. 22-31, 33-

51). The original localities reported for

Rissoa bicingulata: ["Fossile colla prece¬

dente... ( R.tenuicostata Seguenza)... del

plioceno superiore di Messina..." (G.

Seguenza, 1876a: 63) and "E ' notevole che

in questa fauna esistano talune specie che

erano State da me raccolte nel plioceno

Messinese e Reggiano e non ancora conos-

ciute viventi." (G. Seguenza, 1876b:l)],

indicate the inclusión of both Recent and

fossil materials. However, I do not know

filis species from the Recent Mediterranean

fauna. In the Monterosato collection

(MCZR, L.10.22067) there is a lot contain-

ing a fossil specimen (Fig. 5, F-G) of Rissoa

bicingulata G. Seguenza, 1876 from Messina

(ex coll. G. Seguenza), concordan! with

the presen! interpretation, which is here

designated as lectotype, and stabilizes the

use of this ñame.

RESUMEN

Se han encontrado algunos ejemplares de Margaritifera margaritifera en el curso alto del

río Duero, en la provincia de Soria. Se trata de la cita más oriental de esta especie en la

Península Ibérica y la única conocida en el cauce del río Duero. Únicamente se ha locali¬

zado un ejemplar vivo y uno recién muerto. Parecen ser los últimos ejemplares de una

población de la que no se tenía noticia alguna, aunque según los habitantes de los pue¬

blos ribereños existía hace años un elevado número de ejemplares en la zona final del

embalse de Cuerda del Pozo, cerca de Molinos de Duero. Según los datos que se apor¬

tan en el presente trabajo, esa posible población está actualmente extinguida.

ABSTRACT

A few specimens of Margaritifera margaritifera were found in upper Douro River, in the

province of Soria. It is the most eastern record known for this species in the Iberian Penín¬

sula and the only population known in the course of the Douro River. We have only

located two specimens, one live and other ¡ust died. It seems to be the last specimens of

an unknown population. Local people teil that some years ago, there was a large number

of specimens near of the Cuerda del Pozo reservo! r, cióse to Molinos de Duero village.

According to data reported in this paper, this possible population is currently extinct.

INTRODUCCIÓN

La madreperla de río, Margaritifera

margaritifera (Linnaeus, 1758) es una es¬

pecie de náyade con distribución holár-

tica (Araujo y Ramos 2001). En la Penín¬

sula Ibérica su área de distribución cono¬

cida se restringe al cuadrante norocci-

dental (Araujo, Reís, Machordom, To¬

ledo, Madeira, Gómez, Velasco, Mo-

rales, Barea, Ondina y Ayala 2009). Se

conocen poblaciones en ríos atlánticos

gallegos y del oeste asturiano: desde el

Baixo Miño hasta el Narcea (Álvarez-

Claudio, García-Rovés, Ocharán, Ca¬

bal Ocharán y Álvarez 2000; Lois, On¬

dina, Outeiro, Amaro y San Miguel

2014), en ríos del norte de Portugal:

Neiva, Cavado, Paiva, Mente, Rabanal,

Tuela, Terva y Beqa (Reís, 2003; Varan-

das, Lopes-Lima, Teixeira, Hinzmann,

Reís, Cortes, Machado y Sousa 2013) y

en el occidente de Castilla y León (Ve-

lasco y Romero 2006). Concretamente,

en esta última comunidad autónoma, las

poblaciones cuantitativamente más im¬

portantes perviven en la provincia de

Zamora, en los ríos Negro y Tera (cuenca

del Duero) y en el río Bibey (cuenca del

Miño) (Morales, Negro, Lizana,

Martínez y Palacios 2004; Morales,

Santos, Peñín y Palacios 2007). Tam¬

bién hay poblaciones en el sur de las pro¬

vincias de Salamanca (río Águeda,

cuenca del Duero) (Velasco, Araujo,

Bueno y Laguna 2002; Morales y Li¬

zana 2012) y Ávila (río Alberche, cuenca

del Tajo) (Velasco, Araujo, Balset, To¬

ledo y Machordom 2006).

El declive de las poblaciones de esta

especie está ampliamente documentado

(Araujo y Ramos 2001; Geist 2010), de

forma que se ha catalogado como "En

Peligro" tanto a nivel mundial (UICN

2013), como en España (Libro Rojo)

(Araujo 2009). Se encuentra incluida en

el Listado de Especies Silvestres en

Régimen de Protección Especial del Real

Decreto 139/2011, de 4 de febrero, para

el desarrollo del Listado de Especies Sil¬

vestres en Régimen de Protección Espe¬

cial y del Catálogo Español de Especies

Amenazadas. En Europa está protegida

por el Convenio de Berna (Anexo III) y

por la Directiva de Hábitats

(92/43/CEE: Anexo II).

En el presente trabajo se informa de

la localización de los que probablemente

sean los últimos ejemplares de una

población en la cuenca alta del río

Duero, en la provincia de Soria, que se

encuentra a 240 km de la población del

río Alberche y a más de 300 Km del

resto de poblaciones españolas conoci¬

das. Se trata por tanto de la cita más

oriental de esta especie en la Península

Ibérica.

MATERIAL Y MÉTODOS

El área de estudio se localiza al norte

de la provincia de Soria (España), en el

tramo alto del río Duero, entre los 1.100

y los 1.200 m de altitud, que cruza los

términos municipales de Duruelo de la

Sierra, Covaleda, Salduero y Molinos de

Duero; cuadrículas UTM 10 x 10 Km:

TWM04, TWM14 y TWM13 (Figura 1).

El Duero nace en la vertiente meri¬

dional de los Picos de Urbión (Sistema

Ibérico) a unos 2.160 m. en el término

municipal de Duruelo de la Sierra.

Nuestra zona de estudio se sitúa en uno

de los escarpados valles de la Cordillera

Ibérica, donde el núcleo mesozoico

cubre al núcleo paleozoico que asoma

en superficie en el macizo de los Picos

de Urbión. Se trata de un río de

montaña, que recibe el aporte de nume¬

rosos arroyos que bajan de las laderas

circundantes.

Según datos de la Confederación

Hidrográfica del Duero, el caudal medio

anual del río a su paso por la estación de

aforos "Molinos de Duero" es de 3,12

m3/ seg, siendo el caudal medio durante

los meses de julio y agosto de 0,88 y 0,48

m3 / seg respectivamente.

Este tramo del río Duero está

incluido en el Lugar de Importancia

Comunitaria "Riberas del río Duero y

afluentes" (LIC ES41 70083), que incluye

varios cauces de las provincias de Soria,

Burgos, Valladolid y Zamora.

En la zona de muestreo, el río tiene

tramos con bastante heterogeneidad en

cuanto a anchura, con medias de 9,3

metros y máximas (junto a la localidad

de Salduero) de 20 metros. El fondo pre¬

senta un lecho pedregoso, con depósitos

fluviales de grandes bloques y cantos,

conglomeráticos y cu arcítico- arenis co¬

sos, redondeados y acúmulos de arenas

y limos.

Aguas arriba de la localidad de

Covaleda, el río transcurre a través de

un pinar de Pinus sylvestris que presenta

una escasa y dispersa vegetación de

ribera, con robles ( Quercus pyrenaica),

avellanos ( Coryllus avellana ) y serbales

(Sorbus aucuparia), que apenas llegan a

tener porte arbóreo desarrollado, y

diversa vegetación arbustiva. A partir

de Covaleda, el río se ensancha ligera¬

mente, si bien no deja de tener la morfo¬

logía típica de un río de montaña. La

vegetación dominante sigue siendo el

pinar y el roble, que llegan hasta el río,

pero ya aparecen abedules ( Betula alba),

álamos temblones ( Populas trémula),

arraclanes ( Frángula alnus) y sauces

(Salix spp.). Finalmente, aguas abajo de

la localidad de Molinos de Duero, el río

ya se remansa, llegando el pinar hasta la

lámina de agua.

La pendiente media de este tramo de

cabecera es de 8 m/km. El agua tiene una

conductividad en los meses de estiaje de

55 microsiemens y un pH de 6,5.

La comunidad de peces está domi¬

nada por el piscardo ( Phoxinus bigeni) y

el gobio ( Gobio lozanoi), encontrándose

en menores densidades: la trucha

común ( Salmo trutta), la boga (Pseudo-

chondrostoma duriense), el bordallo (Squa-

lius carolitertii), el barbo ( Luciobarbus

bocagei), y la bermejuela ( Achondrostoma

arcasii). A destacar también la presencia

de abundante cangrejo señal (Pacif asta-

cus leniusculus), especie no-indígena

procedente de América.

Los trabajos de prospección se desa¬

rrollaron tras el hallazgo, el 22 de mayo

de 2013, de un ejemplar localizado por

un pescador en la orilla del río Duero, a

la altura del pueblo de Molinos de Duero.

Este ejemplar estaba recién muerto, ya

que mantenía todavía las partes blandas

pegadas a la concha; fue entregado al

personal del Servicio Territorial de Medio

Ambiente de Soria y tras confirmar su

correcta identificación, ha quedado depo¬

sitado en la colección del Museo Nacio¬

nal de Ciencias Naturales de Madrid con

el número 15.07/5344 (Figura 2)

Durante los meses de julio, agosto y

septiembre de 2013, se ha muestreado

tramos situados por encima del pueblo

de Covaleda, así como el tramo final del

río Ebrillos y tramo final del río Revi-

existen las condiciones favorables para la

persistencia de esta especie de náyade.

(Tabla I). Durante los muéstreos poste¬

riores al primer hallazgo de mayo de

2013, únicamente se ha localizado un

ejemplar vivo (Tabla II), que una vez

medido fue depositado cuidadosamente

en el mismo lugar en el que se encontró,

habiéndose comprobado en posteriores

visitas que seguía vivo y anclado en el

mismo punto (Figura 4A,B). Además se

encontraron trozos de conchas de otros

dos ejemplares adultos.

Otros moluscos dulceacuícolas

encontrados en el tramo de estudio son

Ancylus fluviatilis y Pisidium amnicum.

DISCUSIÓN Y CONCLUSIONES

El hábitat (características fisicoquí¬

micas del agua, altitud y granulometría

del sustrato) del tramo donde se han lo¬

calizado los ejemplares (Tabla III), coin¬

cide en líneas generales con los observa¬

dos para esta especie en la Península

Ibérica y, en particular, en Castilla y

León (Velasco y Romero 2006). No

obstante, en el bosque de ribera de la

zona de estudio no existen alisos ( Alnus

glutinosa), una especie habitual en otras

poblaciones de M. margaritifera de la Pe¬

nínsula Ibérica (Velasco et al. 2002;

LIFE-Náyade 2004; Velasco et al.

2006; Morales et al. 2007).

La existencia de M. margaritifera en

la provincia de Soria pone de mani¬

fiesto, una vez más, la hipótesis de que,

en un pasado no muy lejano, la distribu¬

ción de esta especie en la Península

Ibérica era más amplia que en la actuali¬

dad (Bauer 1986). En cuanto a la zona

de estudio de este trabajo, diferentes

habitantes de los pueblos ribereños,

coinciden en afirmar que hace unos 40

años era una especie habitual y que

donde más "mejillones" aparecían era

aguas abajo del puente de Molinos de

Duero, donde se construyó reciente¬

mente la estación de aforos y la depura¬

dora de aguas residuales. Algunas per¬

sonas refieren que además había indivi¬

duos de esta especie en el río Ebrillos

(afluente del Duero afectado también

por la cola del embalse de Cuerda del

Pozo). Como curiosidad, alguna de las

personas entrevistadas asegura que hace

unos 40-50 años las comían, "aunque su

sabor era malo y estaban muy duras, a

pesar de cocerlas mucho".

Por otro lado, el gran tamaño de los

pocos ejemplares encontrados y la

ausencia de juveniles demuestra que,

como ocurre en las otras dos poblacio¬

nes ibéricas más alejadas del cuadrante

noroccidental, en los ríos Agueda

(Velasco et al. 2002; Morales y

Lizana 2012) y Alberche (Velasco et

al. 2006) están extinguiéndose por falta

de reclutamiento (Tabla III).

Otras amenazas comunes en estas

tres poblaciones serían:

-La falta de depuración de las aguas

de los municipios correspondientes,

hasta fechas recientes, agravada durante

los meses de verano por el aumento del

número de habitantes y la disminución

del caudal en los ríos. Esta pérdida de

calidad del agua dificulta el asenta¬

miento e impide el crecimiento de los

juveniles de M. margaritifera y no favo¬

rece a las poblaciones de trucha común.

-Los grandes embalses ubicados en

los tramos inmediatamente inferiores a

los que ocupan las poblaciones de M.

margaritifera. Además de inundar tramos

aptos para M. margaritifera, favorecen la

distribución de los ciprínidos, que se

han hecho predominantes en las zonas

de influencia de los embalses, en detri¬

mento de las poblaciones trucheras.

-Finalmente, otras obras puntuales

(azudes de abastecimiento, depurado¬

ras, estaciones de aforo, ,.) también

provocan la alteración de riberas y la

colmatación de ciertas áreas adecuadas

para M. margaritifera . En nuestra zona

de estudio, las obras de construcción de

la estación de aforos así como de la

depuradora de Molinos de Duero, en el

año 2008, probablemente hayan contri¬

buido a terminar con algunos ejempla¬

res que hubieran podido quedar en las

zonas donde los lugareños coinciden en

afirmar que sus densidades eran

mayores. La remoción del lecho del río

con maquinaria pesada y las sucesivas

detracciones de agua durante las obras

podrían haber acabado con la población

existente (Figura 3B).

Puede decirse que la problemática en

estas 3 poblaciones periféricas amenaza¬

das de M. margaritifera es similar: tramos

de aguas trucheras con un hábitat favo¬

rable para la supervivencia de los ejem¬

plares adultos (granulometría de fondo y

bosque de ribera adecuados) pero que no

permiten el reclutamiento de juveniles

como consecuencia de la pérdida de la

calidad del agua y de la correspondiente

baja densidad de peces hospedadores

(truchas). Se trata por tanto de poblacio¬

nes pequeñas y envejecidas que se extin¬

guirán tan pronto como mueran los pocos

ejemplares adultos que aun se encuentran.

RESUMEN

Se presenta un estudio del material de Pyramidellidae reunido a lo largo de unos 10 años

por los propios autores además del cedido por otros colectores e instituciones. De ese

material se identificaron 260 especies obteniendo nuevos datos sobre el área de distribu¬

ción o el rango batimétrico para 147 de ellas. Veintitrés especies son nuevas para la cien¬

cia y siete más son descritas sin darle nombre. Se comenta y corrige la citación errónea

de Eulimella monolirata para la costa africana. Se establecen las siguientes sinonimias:

ABSTRACT

A study of the Pyramidellidae material gathered over 1 0 years by the authors, with the

addition of that obtained by other collectors and institutions, is presented. In this material,

260 species were identified, and new data on the distribution area or the depth range of

147 species were obtained. Of these, twenty three are new to Science and seven more

are described without giving a ñame. The erroneous citation of Eulimello monolirata for

the African coast is discussed and corrected. The following synonymies are estabiíshed:

Pyramidella schanderi Aartsen, Gittenberger & Goud, 1998 with P ¡nopinata Schander,

INTRODUCTION

In recent decades, the Pyramidelli¬

dae have deserved special attention,

both in Europe and the West African

coast. In Europe their study began with

van Aartsen (1977, 1981, 1987 and

1994) and, for the Iberian Península,

with the work of Peñas, Templado &

Martínez (1996) on the Spanish

* Olerdola, 39-5°C, 08800 Vilanova i la Geltrú (Barcelona), Spain.

** Museo de Historia Natural, Parque Vista Alegre, Campus Norte, 16782 Santiago de Compostela, Spain.

Mediterranean. Meanwhile the study of

the coast of Africa was started by

Nofroni & Schander (1994) and

Schander (1994). Shortly after, Peñas &

Rolán (1997a, 1997b, 1998, 1999a,

1999b, 1999c, 2000, 2001a, 2001b and

2002) and Peñas, Rolán & Schander

(1999) studied extensively the Pyra-

midellidae of the West African coast and

the Atlantic seamounts south of the

Azores. At the same time, Aartsen, Git-

tenberger & Goud (1998) also re-

viewed the Pyramidellids of these areas.

Additional revisions were made in more

general works referred to some areas or

regions, such as that of Garraf (Giribet

& Peñas, 1997), Alboran (Peñas, Ro¬

lán, Luque, Templado, Moreno, Ru¬

bio, Salas, Sierra & Gofas, 2006), An-

dalusia (Peñas & Rolán, 2011), Canary

Islands (Hernández, Rolán & Swin-

nen, 2011), and others.

More recently, the authors have col-

lected in new localities and the material

so obtained is the object of the present

work, showing new records of species

already known and new species to be

described herein. Some genera like Pyra -

midella, Odostomella or Trabecula had not

been revised previously by us.

MLATERIAL AND METHODS

Material collected since the last

Addenda (Peñas & Rolán, 2002) was

obtained by the authors from beach sed-

iments, diving with snorkel or Scuba

and also from dredgings. The sediments

were examined under magnification

and the shells sorted to species attempt-

ing to make a correct determination.

Another part of the material was col¬

lected by the EMEPC / M@Bis / Sel-

vagens 2010 expedition, within the

project M@Bis (Marine Biodiversity

Information System) conducted by the

Portuguese Task Group for the Exten¬

sión of the Continental Shelf. The ship

conducting these campaigns was the

"Creoula" and the material was pro-

vided by Monica Albuquerque.

A large amount of material was col¬

lected by the MNHN during several

expeditions in West Africa (mainly Ivory

Coast, Guinea Conakry, Gabon, etc.)

Occasionally material from some per¬

sonal collections (José María Hernán¬

dez, Jacques Pelorce, Luis Dantart, etc.)

was included in the present study.

In most cases the use of Scanning

Electron Microscopy (SEM) was neces-

sary. For this study an XL-30 set and a

QUANTA-200 microscopes from the

University of Vigo were used.

We have figured all species that

were new or had some difference or

peculiarity compared to the shells of

previously known species.

The comparison of protoconch char-

acters, such as the protoconch type (A, B

or C as shown in Peñas, Templado &

Martínez, 1996, and in other works), its

diameter, the presence of occasional

microsculpture, etc. are considered as an

important basis for species-level separa-

tion. Measurements of shells are given

also following Peñas, Templado &

Martínez, 1996.

SYSTEM ATIC PART

Until very recently the majority of

European authors, including ourselves,

had included in the genus Chrysallida s.

1. as a catch-all, numerous species of this

large group. However, strictly speaking,

the only African species to be included

in Chrysallida are those of the group

Chrysallida canariensis Nordsieck &

García-Talavera, 1979, because they are

the only ones to match the characteris-

tics of the type species Chrysallida com-

munis (Carpenter, 1856).

This view was adopted by Pimenta,

Absaláo & Miyaji (2007, 2009) and

Micali, Nofroni & Perna (2012) limit-

ing the genus Chrysallida to the group of

C. communis and including the other

species of the subfamily Chrysallidinae

in other genera; Schander, Aartsen &

Corgan (1999) cited about 50 genera in

this subfamily. Aartsen, Gittenberger

& Goud (1998), referring specifically to

West Africa, included in the genus

Folinella Dalí & Bartsch, 1904 some

species formerly included in genus

106

PEÑAS ET AL.: The superfamily Pyramidelloidea in West Africa, 11. Addenda 3

Chrysallida; and later, the same authors

Aartsen, Gittenberger & Goud (2000)

provisionally used some subgenera such

as Parthenina, Pyrgulina, Tragula, Sirio-

turbonilla among others.

Lygre & Schander (2010) intro-

duced the new genus Kongsrudia, which

ineludes four already known African

species: K. gruveli (as type species), K.

approximans, K. ersei and K. mutata, and

described a new species, K. rolani.

In the review that the present au¬

thors have completed recently, referring

to deep waters of the South and Central

Tropical Pacific (Peñas & Rolán, in

press), we inelude all the genera related

to Chrysallida in the tribe Chrysallidini,

according to the nomenclature given by

Bouchet & Rocroi (2005). However, af-

ter studying abundant material from the

Tropical South Pacific, we believe

(Peñas & Rolán, in preparation), that

some tribes such as Syrnolini or Tiberi-

ini, need further revisión and this is

planned to be done in the near future.

Distribution: Previously known from

Senegal and the Cape Verde archipelago

(Aartsen et al., 1998). The distribution

is here extended to inelude Ivory Coast,

Sao Tomé and Príncipe, and Angola.

Remarks : Schander (1994) described

Pharcidella inopinata, and compared this

species with Obeliscus suturalis von

Maltzan, 1885. Aartsen et al. (1998)

mentioned that the latter was preoccu-

pied by Pyramidella suturalis Lea, 1846,

giving a new ñame Pyramidella ( Long -

chaeus) schanderi, but they expressed

doubts regarding the identity of Phar¬

cidella inopinata which they found to be

slightly different. We have examined a

large number of shells from many conm¬

ines including the type locality of both

taxa and have not found consistent dif-

ferences between them. For this reason

we think that they are conspecific, being

Pharciella inopinata a júnior synonym.

Since Obeliscus suturalis von Maltzan is a

preoccupied ñame, we will employ the

synonym Pyramidella inopinata (Schander,

1994) as the valid ñame.

is here recorded for the first time from

Gabon, Guinea Conakry and Ivory

Coast.

Remarles: In the opinión of van

Aartsen & Menkhorst (1996) the taxon

Parthenina brusinai employed by other

authors should be superseded by the

earlier ñame P. incerta (Milaschewich,

1916). We have not examined this type

material but accept this opinión.

Description: See Peñas, Rolán &

Ballesteros (2008).

Distribution: Mediterranean of

Catalunya and also central Medi¬

terranean and Adriatic (Mícali, No-

froni & Perna, 2012). The range is

here extended to inelude Mauritania

and Senegal, infralittoral and circa¬

littoral.

Remarles: This species is character-

ized by a tiny, solid, subcylindrical shell,

with flexuose and opisthocline ribs,

wider than their interspaces, vanishing

gradually at the periphery; faint spiral

Iberus, 32 (2), 2014

sculpture, only in the interspaces,

formed by three cordlets, the lower one

placed at the periphery; aperture with a

columellar tooth. We believe that the

fact of this species not being recorded in

most of the Western Mediterranean and

Moroccan Atlantic may be due to its

tiny dimensions.

Etymology: The species ñame is after Jean Paul Kreps, Belgian malacologist, recently passed away.

Description : Shell small, solid,

conical elongated, tending to subcylin-

drical, white-yellowish in colour, shiny,

opaque. Protoconch of type C, obtuse,

with a diameter of about 250 jum. Teleo-

conch of relatively high spire (h = 48%

H on average), comprising 5-6 whorls,

the first ones flat-convex and the later

more convex, angled in the area of the

spiral cord. Suture deep. Axial sculp-

ture formed by about 18-20 orthocline

or slightly prosocline ribs, almost

straight, with an almost rectangular

profile, equal to or somewhat wider

than their interspaces, extending

toward the base to reach the aperture,

but attenuated.

Spiral sculpture only in the inter-

space of the ribs, formed in most spire

whorls by one cord located just above

the suture; in the two final whorls a

second very weak cordlet becomes

present, and another one appearing

along the suture becomes peripheral on

the last whorl. Aperture small (A < 30%

H), pyriform; columella reflected

outward, arched, opisthocline, with a

columellar tooth scarcely prominent but

obvious. Not umbilicated.

Dimensions of the holotype: 2.9 x

0.95 mm; h = 1.37 mm; A = 0.38 mm.

Distribution : Infralittoral, but even

more circalittoral and bathyal, in the

archipelagos of the Canary Islands,

Madeira and Sao Tomé.

Remarks: The shells here assigned to

this new species were known from years

ago, but always caused us doubts: ini-

tially they were considered a form of

Parthenina suturalis (see Hernández et

al. 2011: figs. 84 M-N) and in Peñas &

Rolán (1998: figs. 122-124) they were

considered a form of Parthenina inter-

stincta. However, after the examination

of more than two hundred shells, we

consider that they represent a new valid

species.

C. suturalis (Philippi, 1844),

described from the infralittoral of the

Mediterranean, has a smaller shell with

the same number of whorls, is most

obviously subcylindrical, has a proto¬

conch with a smaller diameter and is

less obtuse, and it has more ribs which

are weaker; the suture, although nar-

rower, is deeper and canaliculated, and

there is only one spiral cord on the

suture.

C. connexa has two spiral cords on

the lower part of the whorls above the

suture, and three on the periphery of the

last whorl, but not the lowest one supra-

sutural.

C. Ínter stincta has a larger, more

tronco-conical and wider shell with one

whorl less at equal height; the whorls

are flatter, the axial ribs are orthocline, a

spiral cord is located closer to the

suture, it is thicker and in no case is

there a second spiral cordlet above the

main one; in addition the interspaces

between the ribs are generally abmptly

interrupted at the periphery of the last

whorl, and it does not have the small

suprasutural cordlet.

C. clathrata has a more acute proto¬

conch, tending to type B, the shell is

more clearly subcylindrical, with more

convex whorls, it has fewer axial ribs,

and from the beginning of the whorls

two spiral cords are observed which, in

the last whorl, become three adding the

peripheral one; all are of the same thick-

ness, equidistant; the aperture is

suboval, with the columellar tooth weak

and internal.

C. dollfusi has a wider shell, with a

shorter spire, with nearly 1.5 whorls less

at equal height, the whorls are almost

fíat, the suture narrow, the spiral cords,

which in the last whorl are three, are

weak and clustered near the suture, the

aperture is wide and the columellar

tooth weak and internal.

Luanda, dredged 10-12 m (MHNS).

Distribution : This species is known in

the infralittoral and circalittoral from

Mauritania to Angola. We extend here

its distribution range to inelude Sao

Tomé Island.

Remarks : This species had been

recorded with dimensions up to 4 mm,

but the shell from Luanda here repre-

sented measures 5.3 mm; moreover, it has

an almost negligible spiral sculpture.

ture in the interspaces formed by about

12 cordlets, and another 10 on the last

whorl, very weak on the base. Aperture

pyriform; columella slightly arched,

opisthocline, with a conspicuous col-

umellar tooth. Not umbilicated.

Iherus , 32 (2), 2014

Remarks : Chrysallida reekmansae

spec. nov. (see below) has a similar

shell, more globose and fragüe, with a

shorter spire, it has more ribs, about

28, as wide as their interspaces, lacks

a columellar tooth and has an umbi-

licus.

Chrysallida pinguis Peñas & Rolán,

1998, has a shell with a more conical

profile, with stepped whorls, it has

fewer ribs that are more robust, proso-

cline, has spiral cordlets which overrun

the ribs and the aperture lacks a col¬

umellar tooth.

Chrysallida obesa (Dautzenberg, 1912)

has a shell that is much larger and more

robust and the protoconch has also a

larger diameter; its profile is oval-conical,

almost cyrtoconoid in adult shells, the

ribs are thicker and wider than their

interspaces, the columellar tooth is very

prominent and it has 5-6 inner spiral

cords visible inside the outer lip.

Chrysallida stefanisi (Jeffreys, 1869)

has a more elevated spire with some

stepped whorls, and lives in deep water.

For comparison we have represented a

shell (Fig. 5H).

Pyrgulina reekmansae spec. nov. (Figures 5F-G)

Type material: Holotype in MMF (43335, Fig. 5F), ex-CFS.

Type locality: off Funchal, Madeira, 32°37.816'N, 16°53.866'W, 382-386 m.

Material examined: Only known from the type material.

Etymology: The specific ñame is after Cynthia Reekmans, miss Belgian Beauty in 2004.

Description: Shell tiny, fragüe,

globose to suboval. Whitish, opaque,

shiny. Protoconch of type C with a

diameter of about 330 pm. Teleoconch

with a very short spire (h = 81% H),

comprising just over two convex

whorls, the last one round at the periph-

ery. Suture deep. Axial sculpture some-

what obsolete in the first whorl, in the

second consisting of about 28 somewhat

irregular ribs, orthocline, rounded in

profile, approximately as wide as their

interspaces, more robust in their adapi¬

cal part, surpassing the profile of the

suture, extending attenuated at the base.

The spiral sculpture formed by about 14

cordlets in the interspaces of the ribs,

almost equidistant, as wide as their

interspaces, plus about 7 weaker

cordlets at the base. Aperture relatively

large (A = 48% H), oval; columella

arched, opisthocline, peristome continu-

ous, without any visible columellar

tooth. Umbilicus narro w but deep.

Dimensions: the holotype measures

1.03 x 0.65 mm; h = 0.85 mm; A = 0.5

mm.

Distribution: Only known from the

type locality, Madeira.

Remarks : We have decided to

describe this species based on a single

shell, since it differs from all known

species in the study area. Chrysallida

pinguis Peñas & Rolán, 1998 also has a

tiny shell but it is robust, its profile is

oval-conical, with the stepped whorls; it

has fewer ribs, about 12-14 on the last

whorl, very robust, few spiral cords,

which conspicuously overrun the ribs,

and it lacks any umbilicus. See also

Remarks in P. vanvelthoveni.

This species shows some limited

resemblance to juvenile shells of

Kongsrudia mulata (Dautzenberg, 1912),

but these are not globose, the profile of

their whorls is stepped, they have less

ribs, about 18-20, much narro wer than

their interspaces between sutures on the

last whorl, and only have 8 spiral

cordlets with very deep and narrow

intervals.

Non-adult shells of Chrysallida ste¬

fanisi (Jeffreys, 1869) (Fig. 5H), which

has been cited from deep water off Mau¬

ritania, Madeira, Canary Islands and the

Azores, have a rather stepped profile,

the suture is very deep, they have less

ribs, about 18, which are more robust

and wider than their interspaces, also

have less spiral cordlets, and do not

have a continuous peristome. The

umbilicus is wider.

Type species: Kongsrudia approximans (Dautzenberg, 1912). By original designation.

Remarles : Lygre & Schander (2010)

wrote that the genus Kongsrudia shows

some similaritíes to the genus Pyrgulina

A. Adams, 1863 (type species Chrysallida

casta A. Adams, 1861, subsequent de-

signatíon Dalí & Bartsch, 1904), but that

the spíral sculpture in this genus is far

less prominent, and the species of Pyr -

gulina also tends to be broader ín

outline. Thís is debatable, but the reap-

praisal of this genus ís beyond the scope

of thís work.

Remarks : A certain variability has

been observed in this species: the shells

from the Mediterranean are larger and

with a very sturdy sculpture, with a

single string at the base apart from the

peripheral one; the shells from Angola

are of much smaller size, less robust.

and a spiral cord below the suture can

be seen (see Peñas & Rolán, 1998: figs.

43-45). Nevertheless the shells here rep-

resented have a size and robustness

similar to those of the Mediterranean,

but have two or three spiral cords on the

base, in addition to the peripheral one.

species is here cited for the first time

from Mauritania and Guinea Co-

between populations in relation to the

number of spiral cords which are on the

lower part of the last whorl and the

number of axial ribs on its upper part.

species may be an endemism from a

small area.

Distribution : Previously known from

the Canary Islands, Madeira, Cape

Verde Islands, Mauritania, Senegal,

Ghana and Angola. The distribution

range of this species is here extended to

the island of Annobón and to Gabon.

Remarks : It has been observed that,

while Annobon is part of the islands of the

Gulf of Guinea, it does not share with Sao

Tomé and Príncipe the presence of species

such as P. saotomensis, with its character-

istic spiral belt on the protoconch. The

species found there shares the main char-

acteristics of P. bilirata, living from the

Canary Islands to Angola, and the small

differences that can be seen in the figures

(spiral cords with an angulous profile and

axial small ribs more marked in the shells

from Annobon) do not seem sufficient to

consider it a different species.

for comparison with the previous one:

being very similar in the teleoconch, P.

bilirata (Figs. 8A-D) has a smooth proto-

Type material: Holotype and two paratypes in MNHN. Illustration of the holotype in Schander

25 m (NHNS). Angola: 2 s, Luanda, 60-100 m (MHNS): 6 s, Namibe (MHNS).

Distribution : Described from Angola,

this species is here reported from Sao

Tomé Island, Cape Verde archipelago

and Ghana.

Remarles : Schander (1994) described

this as a new species considering that its

shells had smaller dimensions, a differ-

ent protoconch and also a weaker axial

sculpture than Odostomella doliolum.

Conversely, Aartsen et al. (2000) con-

síder that it is the same species. In our

opinión, probably they are two dífferent

species, but, although in the countries

south of Ghana O. africana is the domi-

nating morphospecies, other forms

closer to O. doliolum have also been

found. On the other hand, in the

Mediterranean hundreds of shells of the

latter have been studied that hardly

show differences, while in the Canary

Islands the forms found are closer to

those of the South.

We believe that whereas O. bicincta

presents obvious differences which point

to a distinct species, the same does not

happen with O. africana and O. doliolum.

The shell found in Sao Tomé, Lagoa

Azul, - 30 m (Figs. 9A-B) has the typical

ribs of O. africana but presents a proto¬

conch that is very large, globose, with a

diameter of 340 jurri (Fig. 9B), even

greater than that of the O. doliolum. In

contrast, deep waters shells of Gran Ca¬

naria identified as O. doliolum (Figs. 9C-

D) have smaller shells and a protoconch

(Fig. 9E) about 280 pm in diameter.

entire Mediterranean, and from several

countries between Morocco and Angola,

including the Macaronesian archipela-

gos. This species is recorded for the first

time in Selvagens Islands.

Remarles : See remarks in O. africana.

It should not surprise us that be-

sides many collecting places in shallow

water, the species also appears in other

places in deep water. In the Mediter¬

ranean this species is just as abundant

in a few metres depth as at 350 m in the

Garraf area or 200 m in Alborán. It is a

species with an extensive bathymetric

range.

for the first time from Ivory Coast,

Guinea-Bissau, Guinea Conakry,

Gabon and from deep waters of Ma¬

deira.

Remarks: A slightly different form

(Fig. 10G), with a more pronounced sub¬

sutural step, internal lirae not so evident

and protoconch with a more visible

nucleus, was considered at the begin-

ning of this study as a different species,

although after the revisión of many

specimens we carne to the conclusión

that it was a local variation of M. gilsoni.

PEÑAS ET AL.\ The superfamily Pyramidelloidea in West Africa, 11. Addenda 3

Distribution : Known from the cir-

calittoral of the central Mediterranean,

Madeira and the Canary Islands; it is

here reported for the first time from the

island of Fuerteventura.

Remarks : Nofroni & Tringali (1995)

defend some differences between the

Mediterranean and Canary Islands forms,

but do not consider them enough to sepá¬

rate them as different species. Micali (pers.

comm.) believes that they are different

species. In our opinión, we lack sufficient

material to make a decisión, however we

acknowledge that Canary shells have a

larger size, the whorls have an almost

stepped profile and we appreciate clear

spiral microsculpture, which no author

had previously shown.

Iherus , 32 (2), 2014

Distribution : Known from the infralit-

toral and circalittoral of the Atlantic

coast of Europe, the Mediterranean, the

Canary Islands, Madeira, the Cape Verde

Islands and Ghana. It is here reported

from the Selvagens Islands and its depth

range is extended down to 700 m.

Remarks: Peñas & Rolán (1998: figs.

234-240) showed the great variability of

this species. The shells that are figured

here confirm this variability to the point

of creating doubts that the shells of Mas-

palomas (Figs. 15C-D) belong to the

same species: they differ by the tiny size

of the shell (1.2 x 0.6 mm), despite

having a larger diameter of the proto-

conch (255 jum), the more oval profile of

the shell, which is also narro wer (H/D =

2.1), the almost obsolete subsutural

cordlet and the growth lines that are

hardly prosocline. On the other hand,

the shells from deep waters of Madeira

(Figs. 15A-B) present a more conical

profile, wider (H/D = 1.75) with the last

whorl angled at the periphery and with

an evident umbilicus. Accepting that

both belong to a single species, they

would be two extreme forms.

Odostomia sp. 1 (Figures 15E-G)

Material examined: Senegal: 1 s, Saint Louis, 100-120 m (MNHN).

Remarks : A shell (Figs. 13E-G)

included here is the only one found, from

St. Louis, Senegal, at 100-120 m, measur-

ing 1.1 x 0.67 mm, which shares with O.

striolata the shape, the type of protoconch

and prosocline growth lines, but lacks the

subsutural cord, typical of this species. It

also recalls O. hierroensis, but this species

has Fl/D = 2, the growth lines are ortho-

cline, and the protoconch is smaller.

a little larger, the whorls are more

convex, with a quick increase, the last

whorl is rounded at the periphery, and

the columellar tooth is very small, Ínter-

nal.

evidently conical, the last whorl is

angled at the periphery, the growth

lines are orthocline, and the proto¬

conch is of type B, with the nucleus

almost visible.

type locality, Madeira.

Remarks: Odostomia microeques Rolán

& Templado, 1999, live collected from

the littoral of Funchal, Madeira, has a

smaller, oval-cylindrical shell and also a

protoconch (diameter 200 pm) which is

of type B; the whorls are more convex

and the suture deeper, the growth lines

are very marked, as small riblets, very

prosocline, the peristome is very promi¬

nent forming a great umbilical chink

behind the colurnella and the columellar

fold is very internal, not easily observ¬

able.

Odostomia madeirensis spec. nov. also

shows some similarity to some forms of

O. striolata, but this species has a proto¬

conch of type B and has, below the

suture, a typical and evident subsutural

cordlet. Also O. hierroensis has a proto¬

conch of type B, the last whorl of the

teleoconch is rounded at the periphery

and the growth lines are orthocline.

O. micrometrica Peñas & Rolán, 1999

has an oval-conical and narrower shell

(H/D = 2,2), with a higher spire, with

almost stepped whorls, the protoconch

is of type B, the growth lines are flexu-

ose, opisthocline on their upper part, the

aperture is narrower, with a columellar

fold instead of a tooth.

O. kuiperi has a type B protoconch,

the shell is wider (H/D = 1.75) and the

spire is more elevated (h = 66% H), the

whorls are more convex, the last one is

rounded at the periphery.

O. bernardi Aartsen, Gittenberger &

Goud, 1998, described from the Azores,

is a shell of similar dimensions, but the

spire is higher (h = 73% H in the holo¬

type compared to 80% in that of O.

madeirensis), the whorls are stepped and

the suture is very deep with an evident

subsutural shoulder; its protoconch is of

type C, but in the description of the

species it was neither measured ñor

shown in vertical.

Odostomia sp. 3 (Figures 17H-L)

Material examined: Madeira: 6 shells, in front of the airport of Funchal, 190 m (MMF).

Description: Shell tiny, light, conoid,

tending to subcylindrical, whitish,

opaque, shiny. Protoconch of type C,

with a diameter of about 250 jum. Teleo¬

conch with a spire little elevated, com¬

prising three convex whorls, the last one

rounded, almost angled, in the periph¬

ery. Suture shallow, with a weak subsu¬

tural shoulder. Growth lines little

marked, prosocline; without noticeable

spiral microsculpture. Aperture pyri-

form; colurnella slightly arched, opistho¬

cline, with a non prominent, but evident

columellar tooth. Not umbilicate.

Dimensions: the holotype is 1.2 mm

x 0.56 mm.

Distribution: Only known from the

studied locality, Madeira.

Remarks: The material studied is not

in good condition and for this reason,

we decided not to ñame this species.

The comparison with similar species is

the following:

Odostomia brandhorsti Aartsen, Gitten¬

berger & Goud, 1998, described from the

infralittoral and circalittoral of Cape

Verde and Sao Tomé and Príncipe, has a

shell with a higher spire, is wider, has a

1 56

PEÑAS ET AL.: The superfamily Pyramidelloidea in West Africa, 11. Addenda 3

feeble spiral groove below the suture, the

columellar tooth is very small and inter¬

na! and, above all, has a different proto-

conch, with a central cord like a carina.

Odostomia natata Peñas & Rolán,

1999, described from the infralittoral of

Ghana, has a cylindrical shell, with more

convex whorls, the last one being round-

ed at the periphery; the suture is deeper

and it has a small subsutural groove.

Odostomia lesuroiti Peñas & Rolán,

1999, described from Atlantis Seamount

of the Meteor group, has a somewhat

larger shell, but the protoconch has a

much larger diameter (340 jum), is not

smooth; the profile is clearly conical, the

growth lines are very prosocline, the

aperture is pyriform, with a continuous

peristome and it has a small columellar

fold instead of a tooth.

3086, 3 s); CAP (2 s).

Type locality: Cap Esterias, Gabon, intertidal.

Etymology: The specific ñame derives from the Latín adverbe exiliter, which means weak, feeble,

insignificant, alluding to its small size.

Description : Shell very small, solid,

conical tending to suboval, milky white,

opaque, shiny. Protoconch obtuse, of

type C, with a diameter of 280 pm and

in growth, specially in width; the last

whorl is large (h = 72% H on average),

globose, rounded at the periphery.

Suture shallow. Without axial sculpture

except for growth lines that are slightly

prosocline. Without appreciable spiral

microsculpture. Aperture relatively

large (A = 45% H in average), pyriform;

columella thick, slightly arched,

opisthocline, with a prominent columel¬

lar tooth, perpendicular to the col¬

umella. Without a clear umbílicus.

Dimensions: Holotype is 1.5 mm x

0.9 mm.

Distribution: Only known from the

type locality, Gabon.

Remarks: Odostomia scalaris

MacGillivray, 1843 has a very variable

shell but always has a narrow subsu¬

more its whorls do not grow as quickly

in width.

Odostomia kuiperi has a shell with a

higher spire, the whorls are definitely

convex, the aperture has a very small

columellar tooth and the protoconch is

of type B.

narrower shell, the suture is shallower

and has a narrow subsutural belt, the

growth lines are very prosocline and the

aperture is small, suboval, with a nar¬

row umbilicus.The protoconch has a

central spiral cord like a carina.

Odostomia lukisii Jeffreys, 1859 has a

larger shell, with a higher spire (h = 60%

H on average), the whorls are clearly

convex, it has a ratio H/D = 2 (against

1.65 in O. exiliter spec. nov.), the growth

lines are orthocline and it is usually

umbilicate.

conch with a low spire, comprising 3.5

convex whorls, the last one round at the

periphery. Suture deep, not canaliculate.

Without axial sculpture, except for little

marked growth lines, which are slightly

prosocline. Under high magnification

microscopic spiral striae can be seen.

Aperture large (A = 40% H) semicircu¬

lar; columella thickened, slightly arched,

opisthocline, with a prominent columel-

lar tooth in the middle; always with a

narrow but clear umbilicus.

Dimensions of the holotype: 1.66 x

0.85 mm; h = 1.1 mm; A - 0.66 mm.

Distribution: Only known from the

infralittoral of Senegal.

Remarles: Odostomia scalaris has a

more robust shell, opaque, larger, and

although variable in size generally

nearly twice as large for the same

number of whorls, which are less

convex; it has an apparent subsutural

shoulder, the microsculpture is rugged,

consisting of tiny pits, the umbilicus,

when present, is narrower and the pro¬

toconch has almost half a whorl more

visible. Peñas & Rolán (1999a: fig. 192)

figured as O. scalaris a shell from Cap

Vert, Senegal, which we think belongs to

the present new species.

Odostomia brandhorsti has a wider

shell, with less convex whorls, the

growth lines are definitely prosocline,

the colu mellar tooth is weaker and the

protoconch has a spiral cord like a

carina.

Odostomia lukisii has a much larger

and more robust shell, wider, ovoid

nearly globose, with the whorls increas-

ing very quickly in width; the growth

lines are orthocline, the microsculpture

is rough, formed by pits, the aperture is

much larger (A = 46% H) and the proto¬

conch proportionally has a larger diam¬

eter (about 300 ¡um), being obtuse, and

lacking any carinae.

Odostomia circumcordata spec. nov. (Figures 19A-D)

Type material: Holotype in MNCN (15.05 / 60127H, Fig. 19A) and 5 paratypes (MNCN 15.05 / 60127P,

Fig. 19B). Other paratypes in the following: MNHN (IM-2012-2769, 5 s), MHNS (100613, 60 s), RBINS

(MT.3088-3089, 2 s), MMF (43355-43356, 2 s), CAP (5 s) and CFS (2 s).

Type locality: Cap Esterias, Gabon, intertidal.

Etymology: The specific ñame alindes to the subsutural cord which goes around the first whorls.

Description : Shell small, solid and

conical, milky white, opaque and some-

what shiny. Protoconch of type A, with a

semi-submerged nucleus, with a diame¬

ter of about 210 jum. Teleoconch with a low

spire (h = 54% H on average), comprising

about four flat-convex whorls, the last one

slightly angular at the periphery. Suture

deep with a subsutural belt, more evident

in the early whorls, and disappearing on

the last one. Growth lines well marked,

clearly prosocline, without appreciable

spiral microsculpture. Aperture pyriform;

columella slightly curved, opisthocline,

with a narrow but prominent columellar

tooth, perpendicular to the columella;

outer lip not thickened. Without a clear

umbilicus, but with a narrow umbilical

chink behind the columella.

Dimensions of the holotype: 2.3 x 1

mm; h = 1.25 mm; A = 0.7 mm.

Distribution: Known from the type

locality, Gabon. However the specimens

Odostomia apexdemissus spec. nov. (Figures 19E-H)

Type material: Holotype in RBINS (MT.3090, Fig. 19E) and two paratypes in RBINS (MT.3091-3092,

Fig. 19F).

Type locality: Gorée Island, Senegal, 7-12 m.

Etymology: The specific ñame derives from the Latin words apex and demissus, which means deep,

alluding to the very open shape of the protoconch.

Description : Shell tiny, fragile, oval-

subcylindrical, milky white, shiny. Pro¬

toconch relatively wide, obtuse, type C,

with a diameter of about 330 jum. Teleo-

conch with a very short spire (h = 70%

H), comprising a little more than two

slightly convex whorls, the last one oval

at the periphery. There are one or two

sulci at the periphery. Suture shallow.

Without axial sculpture except for the

growth lines, little marked, which are

slightly prosocline. Aperture large,

suboval; columella curved, opisthocline,

with a continuous peristome, and a

small columellar tooth, internal; with a

narrow but deep umbilicus.

Dimensions: the holotype is 1.2 x

0.66 mm.

Distribution : Only known from the

type locality, Gorée Island in Senegal.

Remarles : Liostomia clavula (Lovén,

1846) has a slightly larger shell, with an

evident more subcylindrical profile, the

suture is deeper and with a narrow sub¬

sutural shelf, the umbilicus is wider and

deeper, and it has no peripheral sulcus

or columellar tooth.

Odostomia laicismorum spec. nov. (see

below) has a wider shell, almost globose

(H/D = 1.55 against 1.8 in O. apexdemis¬

sus spec. nov.) the protoconch has a

larger diameter, the growth lines are

orthocline, the aperture is larger, semi¬

circular and the columellar tooth is

more conspicuous, clearly visible.

berger & Goud, 1998, described from the

infralittoral of Mauritania, has a similar

but larger, oval-conical shell, with an

almost stepped profile, with more

convex whorls. The spire is higher (h =

67% H in the holotype, against 75% in

that of O. apexdemissus spec. nov.), the

suture is deeper and has several evident

spiral striae on the periphery; the

growth lines are orthocline (instead of

prosocline), the peristome is discontinu-

ous and the protoconch has a smaller

diameter (it was not measured or repre-

sented in the original description).

Odostomia laicismorum spec. nov. (Figures 19I-K)

Type locality: Talliarte, south of Fuerteventura, Canary Islands, 28°10.39'N, 14°21.866'W, 100 m

(ex CFS).

Etymology: The specific ríame is after Ramón Gómez, malacologist of La Palma, Canary islands,

thanking him for his frequent help.

Description : Shell small, not very

solid, conical, milky white in colour.

Protoconch of type C, tending to B,

rather elevated, with a diameter of

about 300 jUm. Teleoconch with a low

columella slightly curved, opisthocline,

with a little prominent tooth. Not

umbilicate.

Dimensions: 1.8 x 0.9 mm.

Distribution: Only known from

Fuerteventura, Canary Islands.

Remarles : In spite of having studied

only one shell, it is in good condition

and different from the most similar

species, and for this reason we decide to

ñame it.

Odostomia dijkhuizeni Aartsen,

Gittenberger & Goud, 1998, described

from Mauritania has a larger shell,

with a more conical profile, with a

higher spire (h - 60% H), the whorls

are less convex, with slower growth,

the last whorl is angled at the peri¬

phery and the growth lines are ortho-

cline.

Odostomia hierroensis Peñas & Rolán,

1999, described from the Canary

Islands, has a wider shell, the growth

lines are orthocline, and the protoconch

is type B with a diameter of 240 ¡um.

conch presents small differences and it

comes from the littoral, but having only

one shell we have opted for not describ-

ing it now as a new species.

Ondina lacrimaeformae spec. nov. (Figures 21D-E)

Type material: Holotype in MMF (43357, Fig. 21D) and 2 paratypes (MMF 43358-43359).

Type locality: Madeira: Lido, Funchal, 100 m.

Etymology: The specific ñame alindes to its profile which is like a tear.

Descri-ption : Shell tiny, very fragile,

conical-suboval, yellowish, semitrans-

parent, glossy. Protoconch relatively

large, type C, with a diameter of about

280 jum. Teleoconch with a short spire (h

= 77% H), comprising a little more than

two convex whorls, increasing rapidly,

the latest whorl at the periphery. Suture

shallow, with a weak and wide subsu¬

tural belt. The growth lines little

marked, orthocline. Under high magni-

fication in the adapical third of the

whorls, some spiral groove can be

observed, the lower one wider and

deeper, and some striae on the base near

the aperture. Aperture very large (A =

51% H), semicircular; columella very

thin, almost straight, opisthocline, gen-

erating a narrow umbilical chink behind

it. No columellar tooth, only an internal

fold of the columella itself. Outer lip

sharp.

Dimensions of the holotype: 1.3 x 0.7

mm; h = 1 mm; A = 0.66 mm.

Distribution : Only known from the

type locality, Madeira.

Remarks : Ondina mosti has a much

larger and narro wer shell (H/D = 2.2

versus 1.85 in O. lacrimaeformae ) with a

higher spire and a slower growth of the

whorls, the growth lines are opistho¬

cline, the aperture is also narrower and

it has evident spiral grooves at the

lower part of the whorls and at the base.

Ondina strufaldi Peñas & Rolán, 1999,

described from the infralittoral of Cape

Verde, also has a tiny shell, the whorls are

scarcely convex, the last one angular at the

periphery, the suture is narrow but deep,

the growth lines are flexuous, opisthocline

below the suture, it lacks spiral sculpture,

the columellar fold is more conspicuous

and the protoconch is of type B.

This species has some similarity to

young shells of Ondina warreni (Thomp¬

son, 1845) (Fig. 21C), however this

species has flatter early whorls, the col¬

umella has an obvious and typical

outward fold. Odostomia warreni has a

spiral sculpture visible without high

magnification, which consists of regular,

almost equidistant lines, not located on

the upper third as in Ondina lacrimaefor¬

mae spec. nov.

Ondina fragilissima Peñas & Rolán,

2002, described from the infralittoral

and circalittoral of Ghana and Guinea

Conakry, has a much narrower shell

(H/D = 2.3), the growth lines are flexu¬

ous, opisthocline below the suture, the

aperture is very narrow and, above all,

it has a protoconch of type B, with 215

jum in diameter, very high and angled in

profile, with an exposed nucleus.

Distribution: Known from the

infralittoral and circalittoral of several

countries between Mauritania and

Angola. It is reported here for the first

time from Ivory Coast, Guinea Conakry

and Gabon.

Remarks : Aartsen et al. (2000) con-

sidered Syrnola lamothei (Dautzenberg,

1912) as a synonym, but Peñas &

Rolán (1999a: 136, figs. 332-334) desig¬

nated a lectotype and supported the

specific distinction.

Syrnola lancéala spec. nov. (Figures 22A-C)

Type material: Type material: Holotype in MNHN (IM-2000-27673, sp, Fig. 22A) and two paratypes

in MNHN (IM-2000-27674, sp, Fig. 22B)

Type locality: Casamance, Senegal, 12°20.7'N, 16°53.1"W, 15 m.

Etymology: The specific ñame alludes to the elongate form like a lance point.

Description : Shell small, solid, cyrto-

conoid, whitish, vitreous, semi-transpar-

ent, shiny. Protoconch of type A, with a

diameter of about 250 jum, with the

nucleus partly immersed. Teleoconch

with a low spire (h = 60% H), comprising

a little more than four slightly convex

whorls, with a rapid growth in height.

167

IberuSy 32 (2), 2014

the last one oval at the periphery. Suture

shallow, linear, with a narrow subsutural

shelf. Without axial sculpture except

growth lines, little marked, orthocline.

The spiral microsculpture is not apparent

but under high magnification a spiral

sulcus placed at one third above the

suture can be seen. Aperture pyriform;

columella thickened, almost straight,

opisthocline, with a prominent and

oblique columellar tooth. By trans-

parency, about six spiral internal cordlets,

also visible inside the aperture, can be

seen. Not umbilicate.

Dimensions of the holotype: 2.6 x

0.96 mm; h = 1.6 mm; A = 0.96 mm.

Distribution : Only known from the

type locality, Senegal.

Remarks : This species has some simi-

larity to O. schrami Aartsen, Gitten-

berger & Goud, 2000, described from

Mauritania and Guinea; the latter has a

similar profile, but the protoconch is

type B, tending to C, typical of the

genus Odostomia, the shell is less solid,

has a very weak and internal columellar

tooth and lacks spiral cordlets in the

aperture.

Syrnola arae Peñas & Rolán, 2002,

described from the infralittoral of Ivory

Coast, has a much larger shell, although

the protoconch has a similar diameter.

the whorls are fíat, of slower growth in

height, the suture is deeper, lacks spiral

microsculpture and has 8-9 spiral Ínter-

nal cordlets.

Megastomia aliter Peñas & Rolán,

1999 has a shell with an ovabconical

profile, the protoconch is larger, the

teleoconch whorls grow more slowly,

the suture is deeper; the last whorl has a

peripheral spiral cordlet, the columella

is narrower, the peristome is continuous

and the columellar tooth, although

prominent, is narrow, and perpendicu¬

lar to the columella.

Syrnola lamothei (Dautzenberg, 1912)

has a narrower shell (H/D = 3.3 against

2.7 in S. lancéala ) with a higher spire,

with at least one more whorl at equal

height, the convexity of the whorls is

limited to the lower third, the suture is

shallow without a subsutural shelf, and

the protoconch has a much smaller

diameter (195 jum) with three quarters of

the nucleus emerged.

Odostomia desuefacta Peñas & Rolán,

1999 has a smaller shell, oval-conical,

the protoconch is smaller, the teleoconch

whorls have a stepped profile, it has

almost the same H/D but with almost a

whorl less, the aperture is semicircular

with a weak columellar tooth and lacks

internal spiral cordlets.

m (CFS). Guinea-Bissau: 1 s, Bissagos Archipelago, 140-220 m (CLD).

Distribution: Known from the Euro-

pean Atlantic and Mediterranean and,

in the West African Atlantic, from Mau¬

ritania and the Canary Islands. We

increase its range to Senegal and

Guinea-Bissau. It lives from the infralit-

toral to the bathyal, predominantly in

the circalittoral.

Remarks : A shell from Guinea-Bissau

(Fig. 23B) corresponds to the shape of E.

subcylindrata, which Nofroni &

Tringali (1995) considered valid and

different from E. acicula, because of the

smaller diameter of the protoconch and

the first whorls of the teleoconch. In our

opinión, after examination of hundreds

of shells, it is an extreme form of the

same species, with intermedíate forms,

and we therefore consider that it is the

same species.

Eulimella gabonensis spec. nov. (Figures 25B-C)

Type material: Holotype in MNCN (15.05/60129, Fig. 25B) and three paratypes deposited in MNHN

(IM-2012-2770).

Type locality: Cap Esterias, Gabon, intertidal.

Etymology: The specific ñame is that of the country where the material was collected.

Description : Shell small, not very solid,

conical with an almost concave profile,

whitish to grayish, opaque, shiny. Proto-

conch of type B, with a diameter of 310 jum,

with a nucleus in spiral form. Teleoconch

with a relatively short spire for the genus

(h = 49% H), comprising a little more than

five whorls, the first two flat-convex and

the later ones fíat, the last one rather

angular at the periphery; whorls increase

178

PEÑAS ET AL.: The superfamily Pyramidelloidea in West Africa, 1 1 . Addenda 3

in width relatively quickly. Suture shallow

but well marked, linear and somewhat

tilted. Without axial sculpture except for

growth lines, little marked, orthocline or

slightly prosocline. Spiral microsculpture

is not visible. Aperture pyriform; columella

slightly curved, opisthocline, no columellar

tooth visible but with a fold very deep

inside. Not umbilicate.

Dimensions of the holotype: 2.9 x

0.89 mm; h = 1.46 mm.

Distribution : Only known from the

type locality, Gabon.

Remarks: Eulimella kobelti (Dautzen-

berg, 1912) has a shell with a subcylin-

drical profile, the protoconch has a

larger diameter (370 jum), the spire is

higher, the whorls have a regular

growth and the suture is shallower.

Eulimella variabilis De Folin, 1870 has

a narrow shell, cyrtoconoid in the early

whorls, a more elevated spire with a

slower increase in width; the whorls are

flat-convex, the last one oval at the

periphery and a columellar fold can be

seen in the aperture.

Eulimella vanderlandi Aartsen, Gitten-

berger & Goud, 2000, described from deep

water off Cape Verde Islands, has a smaller

protoconch, with a different nucleus, the

spire is higher (h = 44% H) for the same

number of whorls, which have a slower

increase in width (H/D = 3 against 3.9 in

E. gabonensis spec. nov.); the growth lines

are opisthocline and it presents slight axial

thickenings like obsolete ribs.

Eulimella fontanae Aartsen, Gitten-

berger & Goud, 2000, described from deep

water off the Azores, has a protoconch

with a smaller diameter and a different

arch-shaped nucleus, the shell is larger for

the same number of whorls and narrower,

the spire is higher, the whorls are fíat-

convex and the suture is deep.

Eulimella robusta Aartsen, Gitten-

berger & Goud, 1998, described from

deep water off Mauritania, has a similar

profile, but the shell is much higher (the

holotype measured 4.7 x 1.8 mm for the

same number of whorls) and wider; the

protoconch is obtuse, has a much larger

diameter, about 450 ¡um, with different,

barely emerged arch shaped nucleus,

the last whorl is clearly angular at the

periphery and the suture is deeper.

Eulimella talea spec. nov. (seebelow) has

a smaller shell for the same number of

whorls, with a more conical profile, a pro¬

toconch of type A-I planispiral; the teleo-

conch whorls are fíat with a subsutural

depression like a belt, the aperture is semi¬

circular without any columellar fold.

Type material: Holotype (Fig. 25D), in MNCN (n° 15.05/27811). Paratypes in: CAP (10 s), from the

type locality; MNHN (IM-2012-2771, 3 s), RBINS (MT.3097, 1 s), MHNS (1000614, 3 s) and CFS (5

s) from Mauritania, 60-80 m.

Other material examined: Senegal: 4 s, Saint Louis, 100 m (CFS). Angola: 4 s (CAP), 4 s (MNHN)

Palmeirinhas, 60-80 m. Sao Tomé and Príncipe: 2 s (CAP), 4 s (MHNS), Santo Antonio, 8 m.

Etymology: The specific ñame alindes to the confusión of this species in previous papers by the

authors.

Description : Shell very small, thin but

strong, subcylindrical, white vitreous,

shiny. Protoconch of type A-I planispiral,

with 2.5 whorls, whose profile protrudes

from the suture of the first whorl of the

teleoconch, with a diameter of about 310

pm. Teleoconch with an elevated spire.

comprising 6-8 whorls, slightly convex,

with the convexity in the lower third, the

last one oval at the periphery. Suture

shallow, linear with a kind of weak dupli-

cate suture above it, and a depression

below the suture producing a spiral cord.

Without axial sculpture except growth

179

Iberus , 32 (2), 2014

lines that are prosocline. Ocasionally

between 1-3 fine spiral sulci can be seen.

Aperture suboval; columella curved,

opisthocline, no colurnellar tooth. Not

umbilicate.

Dimensions: the holotype measures

2.4 x 0.6 mm.

Distribution : Known from the

infralittoral and circalittoral of Maurita¬

nia, Senegal, Ghana, Angola, and Sao

Tomé and Príncipe Islands.

Remarks : We made the mistake (Peñas

& Rolán, 1997b) of citing Eulimella mono -

lirata (De Folin, 1872) as coming from West

Africa, even designating a neotype, when

the type locality of this species is Hong

Kong, and it is difficult to suppose that the

species can range so far away. As a result,

the African species should be considered

a valid species, different from the taxon E.

monolirata (De Folin, 1872) and presenting

obvious differences with all the known

species of this genus in the study area.

The neotype designated in that publication

(1997b) is invalid because it does not orig¬

ínate from near the original type locality

of Eulimella monolirata and it becomes the

holotype of the new species here described.

Aartsen et al. (2000) erroneously

consider this species as being the same as

£. gofasi (Schander, 1994) (Fig. 25F); both

have a similar profile, the protoconchs

are obtuse, but the teleoconchs have

clearly different sculptures: the spiral

sculpture of E. gofasi is formed by four

clear furrows between sutures whereas E.

perturbata may have occasionally 1-3 fine

spiral sulci, but usually is smooth except

for the subsutural depression; its suture

is shallower and does not have the

narrow step and the duplícate appear-

ance; in additíon, the growth lines are

more prosocline than in E. gofasi.

E. polygyrata (Dautzenberg, 1912) has

a conical shell, much larger and also its

protoconch has a larger diameter (350

jum), the whorls are very convex, the

suture is deeper without duplícate

suture and the growth lines are very

marked.

E. kobelti (Dautzenberg, 1912) has a

larger shell, with a conical profile, the

protoconch has a much larger diameter

(370 jum), the whorls are fíat with a very

shallow suture similar to that of the

genus Eulima.

Type locality: Cap Esterias, Gabonj intertídal.

Etymology: The specific ñame refers to the shape of the shell like a pointed stake.

Description: Shell small, thin, fragüe,

corneal, somewhat cyrtoconoid in the early

whorls, white, vítreous, shiny. Protoconch

of type A-I, plardspiral, wíth 2.25 whorls,

and a diameter of about 250 |im. Teleo-

conch with very hígh spíre, comprisíng

six whorls, the first two flat-convex and

the subsequent ones flat, with a belt-like

depressíon or concavity below the suture;

last whorl oval at the períphery. Suture

narrow but deep, linear. Wíthout appre-

dable axial sculpture except for growth

lines that are slightly prosocline. Aperture

semicircular; columella straight, very

opisthocline, perístome continuous,

without appreciable columellar fold or

tooth. Not umbilicate.

Dimensions: the holotype measures

2.13 x 0.54 mm.

Distribution : Only known from the

type locality in Gabon.

Remarks: We have decided to

describe this new species, in spite of

there beíng a single specimen known,

because ít is an adult shell that ís very

different from any other species known

in the study a.rea.

E. acicula has a shell of subcylindri-

cal profile, the protoconch is of type A TI

helicoid, with a larger diameter and 2.75

whorls, the teleoconch whorls are flat-

convex, the subsutural depression is not

visible, the growth línes are orthocline

and the aperture is rhomboíd.

E, fontanae Aartsen, Gíttenberger &

Goud, 2000 has flat-convex whorls, the

last one is angled at the períphery, it has

no subsutural belt, the aperture is pyri-

form, and the protoconch is of type B.

E. kobelti (Dautzenberg, 1912) has a

larger shell with a protoconch of much

larger diameter, more than 350 ¿um, wíth

0.25 whorl more, the suture is very

shallow, and the aperture lacks a subsu¬

tural belt and is pyriform. See also

remarks under E. gabonensis.

jUm, the nucleus with the suture in "G"

form. Teleoconch with a hígh spire, com¬

prisíng about 9 whorls of slow increase in

height, flat-convex, wíth the convexity on

their lower part, the last whorl angular at

deep water species, with a similar shell

profile, but larger, havíng fíat whorls, a

shallow suture, opisthocline growth

lines and a type A protoconch.

Eulimella bogii has a smaller, nar -

rower shell with rapid increase of the

Eulimella robusta, also typical of deep

water, has a shell similar in profile, but

with a faster growth of the whorls (at

equal height it has 3 whorls less), the

whorls are almost flat-concave, and the

protoconch is much higher (about 450

¡im) with a spiral shaped nucleus that is

barely visible.

Eulimella angelí has a higher, nar-

rower shell, the growth lines are

opisthocline, and the protoconch is of

type A with a very prominent nucleus.

Eulimella sólita spec. nov. (Figures 25M-0)

Type material: Holotype in RBINS (MT.3102, Figs. 25M-N) and 3 paratypes (RBINS, MT.3103-3105).

Type locality: Dakar, Senegal, 20-40 m.

Etymology: The specific ñame is derived from the Latin word solitus -a -um, which mean "the usual,

customary", rnaking reference to the morphology similar to that of many specíes.

Description : Shell small, not very

solid, conical, white, vitreous, shiny.

Protoconch of type B, with a diameter of

about 300 jum, with the suture of the

nucleus in a spiral shape. Teleoconch (h

= 35% H) with a high spire, comprising

5-6 flat-convex whorls, the convexity sit-

uated in the middle of the whorls,

which are slightly stepped, the last one

oval at the periphery. Suture deep,

sloping, with a weak subsutural shoul-

der. Without axial sculpture except the

growth lines, which are orthocline.

Spiral microsculpture is not appreciated.

slightly curved, opisthocline, without

appreciable columellar tooth. Not

umbilicate.

Dimensions of the holotype: 3.85 x

0.95 mm; h = 1.4 mm; A = 0.85 mm.

Distrihution : Only known from the

type locality in Senegal.

Remarles : Eulimella polygyrata

Dautzenberg, 1912 has a much larger

protoconch, globose, about 350 ¿um in

diameter, which protrudes from the

profile of the first whorl of the teleo¬

conch; the teleoconch has clearly convex

whorls, with slower growth in height,

the last whorl is rounded at the periph¬

ery, it has an internal spiral cord visible

by transpareney below the suture and

also a subsutural groove, and the aper¬

ture is subcircular.

Eulimella kobelti (Dautzenberg, 1912)

also has a much larger protoconch (350

jum), protruding out of the profile of the

teleoconch, which is subcylindrical,

with fíat whorls, the suture is shallow

and the growth lines are prosocline.

Eulimella ignorabilis Peñas & Rolán,

1997, has a wider protoconch exceeding the

profile of the first whorl of the teleoconch,

the teleoconch whorls increase much faster

in height, the spire is shorter (h = 40% H)

and the growth lines are prosocline.

Eulimella variabilis de Folin, 1870 has

a larger, wider shell, with nearly fíat

whorls, the suture is shallower, the

growth lines are prosocline, it has a

spiral cord at the center of the whorls,

visible by transpareney, which actually

is the columellar fold that can be

observed inside the columella; its proto¬

conch stands out from the profile of the

first whorl of the teleoconch.

Eulimella buijsi Aartsen, Gittenberger

& Goud, 2000, described from deep

water off Cape Verde Islands, has a pro¬

toconch with a larger diameter (400 jum),

the shell is wider (h/D = 3.1 versus 4 in

E. sólita), it has a whorl less for the same

height, and the whorl is nearly angular

at the periphery.

rowly conical tending to subcylindrical,

white, vitreous, shiny. Protoconch of

type B, with a diameter of about 250 ¡im.

Teleoconch with a high spire, compris-

ing seven flat-convex whorls, regular in

growth, the last whorl rounded at the

periphery. Suture shallow. No sculpture,

except for growth lines that are ortho-

cline, very thin. Spiral microsculpture is

not visible. Aperture pyriform; col-

umella thin, slightly opisthocline. No

columellar tooth. Not umbilicate.

Dimensions of the holotype: 3.05 x

0.95 mm; h = 1.20 mm; A = 0.7 mm.

Distribution : Only known from deep

water of Madeira and Canary Islands.

Remarks: Eulimella coysmani spec . nov.

has a larger shell, with a clear conical

profile, the whorls are flatter, the last

one is angular at the periphery, the aper¬

ture is subquadrangular with the col-

urnella orthocline.

Eulimella zornikulla Schander, 1994

has a narrow shell, the whorls are

convex, with a subsutural belt and it has

a protoconch of type A, with a promi-

nent nucleus.

Eulimella similebala Peñas & Rolán,

1999, described from deep water of the

submarine Meteor banks South of the

Azores, has a very globose protoconch,

with the nucleus barely marked, the

whorls are clearly convex, the growth

lines are opisthocline.

Eulimella sinuata Aartsen, Gitten-

berger & Goud, 1998, described from

deep waters of the Cape Verde Islands,

Eulimella sp. 1 (Figures 26F-H)

Material examined: One shell, from Guinea Conakry, W Yomponi River, Exp. "Sedigui II", Stn.

724, 10°24'N, 15°21'W, 21 m (MNHN).

Description: Shell conical very elon-

gated, solid, white, opaque. Protoconch

very inclined. Growth lines prosocline.

Remarks : This shell is very similar to E.

variabilis, but has a sharper protoconch,

with a larger diameter, the whorls are fíat

and there is one less whorl for equal height.

E. ignorabilis also has a protoconch

with a larger diameter, the whorls of the

teleoconch grow much faster, the con¬

vexity is at the center of the whorls, and

it lacks any columellar fold.

Eulimella boydae Aartsen, Gitten-

Peñas & Micali, 1999, with a colour

band placed in the same area and a

similar columellar fold but the proto-

conch is different, of type B and helmet-

shaped, with a concealed nucleus, while

it is visible in E. carminae; besides its

whorls increase more quickly in width

and it has a subsutural step.

New material examined: Gabon: 6 s. Cap Esterias, intertidal (MHNS).

Distribution : Known from the infralit¬

Remarks : The form shown here, identi-

fied in Peñas & Rolán (2002: figs. 121-123)

as Turbonilla sp. 4 was cited previously only

from Miamia, Ghana, between 45 and 65

meters deep. These shells resemble T. gha¬

nensis (Fig. 28D) in protoconch type, as well

as in sculpture, but this species is charac-

terized by its serrated profile due to the

presente of a subsutural cord which seems

like a second suture, while in the shells of

Figs. 28E-F and of Turbonilla sp. 4 (of Peñas

& Rolán, 2002) that cord is obsolete.

However, since other features match the

type material of T. ghanensis we consider

that it could be a form of this species.

Remarks : Aartsen at al. (2000) asso-

dated this species wíth Eulimella rather

than Turbonilla, íllustrating a shell with

almost obsolete ribs. However, the illus-

tration of Tomlin & Shackleford (1914:

fig. 3) as well as the ímages ín Peñas &

Rolán (1997b), in addition to the large

number of examined shell s, allow us to

condude beyond doubt that this species

belongs to the Turbonilla group. The spedes

that Gofas, Pinto Afonso & Brandao

bonilla sp. 2).

Etymology: The specific ñame is after Gabriela Peñas Villén, granddaughter of the first author.

Description: Shell relatively large,

solid, regularly conical, white, opaque

and glossy. Protoconch large, globose, of

type B, with a diameter of 400 jum, with

the suture of the nucleus in spiral. Teleo-

conch with a high spire (h = 41% H with

6 whorls; 35% with 8 whorls); whorls

slightly convex, the last one almost

angular at the periphery. Suture shallow.

Axial sculpture formed by 20-22 small

high ribs, angled in profile, orthocline,

much narrower than their interspaces;

both ribs and interspaces are inter-

rupted below the periphery of the last

whorl. Spiral sculpture consisting of

about 8 spaced grooves, narrow, only in

the interspaces; there is also an axial

microsculpture which forms a kind of

reticule with spiral grooves in the ínter-

space of the ribs. Base with spiral striae.

Aperture small, rhomboid; columella

opisthocline, without visible columellar

tooth.

Dimensions of the holotype: 4.3 x 1.2

mm with 6 whorls of teleoconch; the

shell from Mauritania measures 6.5 mm

with 8 whorls; the shell from Angola

measures 8.5 mm with 9 whorls.

Distribution : Only known from the

circalittoral of Mauritania, Senegal and

Angola.

Remarks : In Peñas & Rolán (2002)

this species is cited and illustrated as

"sp. 2", and it was not described as a

new species because of lack of enough

specimens. The discovery of this third

specimen has induced us to describe it

as a new species, presenting a different

sculpture from the remaining species in

the study area.

Turbonilla fuscoelongata Peñas &

Rolán, 1997 described from the infralit¬

toral of Angola, has a protoconch of

type A, with a much smaller diameter,

the ribs are rounded in profile, as wide

as their interspaces, it has spiral cords

instead of grooves, and these are more

numerous.

Turbonilla gruveli Dautzenberg, 1912

has a larger protoconch, the fresh shells

have two bands of reddish colour

between the sutures, it is narrower, the

whorls are more convex, the suture is

very oblique, the ribs are wider, rounded

in profile, it has much wider spiral

grooves, as wide as their interspaces.

Turbonilla pablopenasi spec. nov. (Figures 31D-G)

Type material: Holotype in MNCN (15.05/60133, Fig. 31D); Paratypes in: MMF (43363, 1 s, Fig.

31E), RBINS (MT.3107, 1 s), MNHN (IM-2012-2774, 3 s); MHNS (100616, 1 sp, 9 s, 8 j); CAP (1 sp, 3

s); CFS (2 s).

Type locality: Gorée L, Senegal, dredged in 10-12 m.

Other material examined: Senegal: 5 s, Dakar, off the Oceanium Hotel, 10-15 m (MHNS).

Etymology: The specific ñame is after Pablo Peñas Villén, grandson of the first author.

Description: Shell small, solid, conical

to subcylindrical, narrow. In fresh shells

the colour is pink, with a band of the

same color but darker, located in the

lower third of the whorls; fading to

whitish in non-fresh shells. Protoconch of

type B, with a diameter of about 310 jum,

the nucleus suture, visible in its entirety.

Teleoconch with a very high spire (h =

30% H), comprising 8-9 slightly convex

whorls, the last one round at the periph-

ery. Suture shallow, slightly wavy.

Axial sculpture formed by about 20

orthocline ribs of rounded profile,

approximately as wide as their inter-

spaces, fading gradually at the periph-

ery of the last whorl. Spiral sculpture

only in the interspaces, formed by 7

rows in the early whorls, and 8-9 on the

last, much narrower than their inter¬

spaces and about 3 spiral striae in the

base. Under magnification it is seen that

in the interspaces of ribs there are axial

ridges crossed by other spirals, forming

a kind of reticle. Aperture pyriform; col-

umella curved, opisthocline, no col-

umellar tooth. Not umbilicate.

Dimensions of the holotype: 5.9 x 1.3

mm.

Distrihution : Only known from the

type locality, Gorée and Dakar in Senegal.

Remarles: Turbonilla gruveli Dautzen-

berg, 1912 has a significantly larger shell

(the lectotype is 9 mm with 10 whorls),

different color, with two bands between

sutures, also the protoconch is much larger

in diameter (about 420 jum), the teleoconch

profile is clearly conical, the ribs are proso-

cline and it has many spiral grooves.

Turbonilla secernenda Dautzenberg,

1912 has a shell that is slightly larger for

the same number of whorls, and a pro¬

toconch that is proportionally larger,

globose, with a diameter of 360-370 jum;

it has spiral cords instead of grooves.

closer together and the microsculpture

of the interspaces is not reticulate.

Turbonilla rubioi Peñas & Rolán, 1997

has a wider shell (H/D = 4.1 to 4.9 in T.

pablopenasi for the same number of

whorls) and a shorter spire (h = 35% H,

also for the same number of whorls), the

protoconch is more obtuse, with a

smaller diameter, the teleoconch whorls

are slightly stepped, the ribs are less

robust, rather low, prosocline and it has

many spiral grooves, about 18 on the

penultimate whorl.

Turbonilla inaequabilis Peñas & Rolán,

1997 has a smaller shell, wider (H/D = 4),

the protoconch is obtuse, with a nucleus

partly not visible; suture less deep, less

ribs, about 16 of angular profile, rather

narrower than their interspaces, in which

there are about 14 spiral grooves and at

the base there are 7-8 spiral striae.

Turbonilla rafaeli has a smaller, sub¬

cylindrical, yellow shell, the protoconch

is proportionately larger, the teleoconch

has slightly convex whorls, but with the

convexity in the lower third, the last

whorl is nearly angulose at the periph-

ery, it has less axial ribs, half as wide as

their interspaces, which have about 10

spiral grooves of almost equal width in

their interspaces.

Turbonilla pablopenasi spec. nov. has a

shell similar to T. gabrielae spec. nov. but

with a higher spire, it has almost two more

whorls for the same height (4.5 mm), it is

narrower for the same height and has a

ratio H / D - 4.2 versus 3.65 in T. gabrielae ;

the whorls are more convex, the last one

is more rounded at the periphery, the pro¬

toconch has a much smaller diameter (310

jum versus 400 jum in T. gabrielae spec.

nov.). However the most constant charac-

ter is the colour difference: the shell of T.

pablopenasi is pink with a more or less dark

color band, while T. gabrielae is white.

Turbonilla sp. 1 (Figures 32 A-D)

Material examined: Guinea-Bissau: 3 s, Bissagos Archipeiago, 140-238 m (CLD).

Description: Shell small, solid, cónica!,

whitish, opaque, somewhat shiny. Proto¬

conch of type B, with a diameter of about

340 jum, with the suture of the nucleus in

spiral, attached to the first whorl of the

teleoconch. Teleoconch with a low spire,

comprising 6 slightly convex whorls, the

last one angular at the periphery. Suture

shallow, linear. Axial sculpture formed by

about 15 ribs, almost orthocline, irregular,

somewhat narrower iban their interspaces,

interrupted in the periphery of the last

whorl. Only in the interspaces, spiral

sculpture formed by very narrow, not

equally spaced grooves, about 10 between

sutures of the penultimate whorl. Some

spiral grooves on the base. Aperture sub-

quadrangular; columella orthocline

without columellar tooth. Not umbilicate.

The shell of Figure 32A-B measures

3.4 x 1.1 mm.

Remarks: The shells are probably not

fully adult. They have a certain resem-

blance to T. martae Peñas & Rolán, 1997

in shape and sculpture, but this species

has a very different protoconch, of type

A, with a very prominent nucleus.

They also resemble immature shells

of T. striatula (Linnaeus, 1758), known

from the South European Atlantic and

201

Iberus , 32 (2), 2014

Mediterranean, but this species has a

larger shell for the same number of

whorls, the ribs are markedly varicose,

the colour is palé brown with darker

bands, the protoconch has a larger

diameter and a different nucleus.

Turbonilla abrardi has a pinkish colour

on the shell, the whorls are quite convex,

the last one rounded at the periphery, it

has more axial ribs, the spiral sculpture is

composed of cords and the protoconch

has an arch shaped nucleus.

Turbonilla sp. 2 (Figures 32E-G)

Material examined: Congo: 1 s, Exp. "Kounda" (MNHN).

Description: Shell small, solid, conical.

Whitish, opaque and shiny. Protoconch of

type B, with a diameter of about 290 ¡i rn,

the suture of the nucleus in spiral form.

Teleoconch with a very high spire (h =

35%H), with about eight whorls slightly

convex, the last one oval at the periphery.

Suture deep. Axial sculpture formed by

about 18 slightly prosocline ribs, sorne-

what narrower than their interspaces.

Spiral sculpture in the interspaces formed

by about 12 very narro w spiral cordlets.

Dimensions: the photographed shell

measures 6.5 x 1.5 mm.

Remarks : T. lozoueti Peñas & Rolán,

2002 has a subcylindrical shell and the

spiral sculpture consists of 8 grooves

between sutures of the last whorl.

T. parsysti Peñas & Rolán, 2002 has a

much smaller shell, but the protoconch

is larger, the teleoconch whorls are

stepped, the last one is angled at the

periphery.

T. inaequabilis has a smaller and

wider shell and the last whorl is angled

at the periphery, the suture is shallower

and the spiral sculpture consists of 14

rows between sutures on the last whorl.

FINAL COMMENTS

For the present work about 9000

specimens, both adult shells and juve¬

niles, have been examined. Thís material

was collected by different persons and

institutions over the last ten years. The

material recorded for those specíes

included in this work is composed of

about 6000 shells,

In total about 260 species have been

identified. In a ratio of 25% the species

identified did not add new Information

to the distributions and faxonomy

already known. In 75% the information

increased the known distríbution area

for the species, by including additíonal

countries or extending the depth range.

Thirty species are apparently new to

Science, and although in 7 cases we had

doubts that made us inelude them as

sp., without naming them, 23 others

were named in this work.
