The peer-reviewed series Bonn zoological Bulletin — Supplementum, formerly “Bonner zoologische Monographien”,

has existed since 1971. It is published by the Zoological Research Museum Alexander Koenig — Leibniz Institute for

Animal Biodiversity (ZFMK), Bonn. Supplements on focus topics are produced in irregular succession. The BzB-S

consists of original zoology papers too long for inclusion in our institute’s regular journal, Bonn zoological Bulletin.

Preferred manuscript topics are: systematics, taxonomy, biogeography, anatomy, and evolutionary biology. Manuscripts

should be in American English. Authors are requested to contact the managing editor prior to manuscript submittal.

For subscription, back issues and institutional exchange, please contact the ZFMK library (ZFMK, Bibliothek,

Mareike Bollen, Adenauerallee 160, 53113 Bonn, Germany, tel. +49 228—9122—216, fax: +49 228—-9122-—212;

Abstract. The species of the Neoserica major, N. uniformis, N. dianae, N. funiushanensis, N. multifoliata species groups,

as well as all other species incertae sedis of Neoserica Brenske, 1894 are revised, while additional taxa were discovered in

the N. calva group. The study resulted in three new combinations, Neoserica insubida (Brenske, 1898) comb. n., N. major

(Arrow, 1946) comb. n., and N. sigillata (Brenske, 1898) comb. n., and the description of 39 new species from China:

primary homonymy, Neoserica (s. str.) schoolmeestersi Ahrens nom. n. is given as replacement name for the Thai species

Neoserica (s. str.) vicina Ahrens, 2003 (nec Moser, 1915). A key to the genera of Sericini with multilamellate antennae,

species-groups of Neoserica from mainland Asia, as well as a key to the individual species of the species-groups examined

here are provided. A map of the species distribution is given; habitus and male genitalia are illustrated.

Key words. Beetles, chafers, Neoserica, China, new species, new records.

INTRODUCTION

In the course of the revision of the genus Neoserica Bren-

ske, 1894 of China a recent series of papers were pub-

lished (Ahrens et al. 2014a—c, Liu et al. 2014a—c, 2015,

Liu et al. 2016). In continuation of this work, addition-

al new taxa were discovered for the N. calva group; we

present the results of the taxonomic revisions of the Neo-

serica major, N. uniformis, N. dianae, N. funiushanensis

Species groups as well as of all species of uncertain sys-

tematic assignment (species incertae sedis).

Neoserica (sensu lato) comprises a polyphyletic mix of

larger species with multilamellate antenna (Ahrens 2003,

2004, Liu et al. 2014a—c, 2015, 2016). They need a revi-

sion of generic nomenclature once they are better known

in their taxonomy, morphology, and phylogeny. The treat-

ment of the species of uncertain systematic assignment

remains particularly complicated as the relationships to

4 Wan-Gang Liu et al.

other groups of species remain obscure and would bene-

fit from future investigations, especially once the neigh-

bouring faunas of Asia are better known.

MATERIAL & METHODS

The terminology and methods used for measurements,

specimen dissection and genital preparation follow

Ahrens (2004). Data from specimens examined are cited

in the text with original label contents given in quotation

marks, multiple labels for a single specimen are separat-

ed by a “/’. Descriptions and illustrations of new taxa

are based on the holotype specimen if not otherwise stat-

ed, while the variation of specimens is given separately

under ‘variation’. Male genitalia were glued to a small

pointed card and photographed in both lateral and dorsal

views using a stereomicroscope Leica M125 with a Leica

DC420C digital camera or a Zeiss AxioCam HRc mount-

ed on a Zeiss Stereo Discovery V20 stereo-microscope.

A number of single focussed images were combined with

the Automontage software in order to obtain an entirely

focussed image. The resulting images were subsequently

digitally edited.

Remarks. The species has in the identification key (p.

51) of the original publication (Liu et al. 2014) errone-

ously the name Neoserica napoana which has to be con-

sidered as nomen nudum.

Diagnosis. Neoserica dashanensis sp. n. differs from all

other species of the Neoserica calva group by the strong-

ly asymmetrical apex of the phallobase, having the inser-

tion of the left paramere strongly displaced distally.

Etymology. The new species is named after the type lo-

cality, Mt. Dashan (adjective in the nominative singular).

can be distinguished from the latter by the concave sinua-

tion located before the apex of the right paramere, as well

as the left paramere being wide and lens-shaped, lacking

a blunt ventral tooth before its apex.

Etymology. The new species is named after the type lo-

cality, Bailongshan (adjective in the nominative singu-

lar).

Variation. Body length: 5.9-6.6 mm, length of elytra:

4.24.8 mm, width: 3.4-3.6 mm. Female: Eyes as large

Diagnosis. Neoserica (s.l.) paramajor sp. n. is in the

shape of its genitalia similar to NV. major. The new taxon

differs from the latter by the distal portion of the aedea-

gus including the fused parameres being shorter than the

phallobase (distal portion longer than the phalloboase in

N. major).

Etymology. The name of this species (adjective in the

nominative singular) is based on the combined Greek

prefix para- (close to) and the species name “major”,

with reference of its similarity to Neoserica major.

Variation. Body length: 7.9-9.1 mm, length of elytra:

Aedeagus: Fig. 7A—C. Habitus: Fig. 7D.

Diagnosis. Neoserica allorubiginea sp. n. is in the shape

of its aedeagus very similar to N. rubiginea. It can be dis-

tinguished from the latter by the apical half of the aedea-

Bonn zoological Bulletin Supplementum 64: 1—71

gus being strongly bent before its apex rather than being

evenly curved as in N. rubiginea.

Etymology. The name of this species (adjective in the

nominative singular) is based on the combined Greek

prefix allo- (different to) and the species name “rubig-

inea’, with reference of its similarity to Neoserica ru-

biginea.

Variation. Body length: 10.6—11.0 mm, length of elytra:

7.4—7.5 mm, width: 6.4-6.6 mm. Female: eyes as large

as in male; antennal club with four antennomeres and

straight, distinctly shorter than remaining antennomeres

combined, first joint of club one third as long as club;

pygidium weakly convex.

lacks a lateral blunt tooth.

Etymology. The new species is named after its type lo-

cality, Mt. Liang-shan-ding (adjective in the nominative

singular).

Variation. Body length: 8.6—10.0 mm, length of elytra:

7.0-7.9 mm, width: 5.6—5.9 mm. Female: eyes as large

Diagnosis. Neoserica milani sp. n. differs from all other

taxa with a setose ventral median part of the phallobase

by the wide left paramere fused at its base with the phal-

lobase being as wide as the entire phallobase at the level

of the insertion of the left paramere.

Etymology. The new species is dedicated to Milan Niko-

dym (Prague, Czech Republic) as thanks for the donation

of his Sericini collection to D.A (noun in genitive case).

Variation. Body length: 8.4-9.0 mm, length of elytra:

5.8—6.2 mm, width: 4.8-5.0 mm. Female: eyes as large

as in male; antennal club with four antennomeres and

straight, slightly shorter than remaining antennomeres

combined, first joint of club half as long as club; pygidi-

um weakly convex.

Diagnosis. Neoserica pararubiginea sp. n. differs from

all other taxa with a glabrous ventral median part of the

phallobase by the apical half of the aedeagus being bent

and not twisted (but straight) after the middle, as well as

in having neither a ventral subapical nor a lateral tooth.

Etymology. The name of this species (adjective in the

nominative singular) is based on the combined Greek

prefix para- (close to) and the species name “rubigin-

ea’, with reference of its general similarity to Neoserica

rubiginea.

Female unknown.

Diagnosis. Neoserica strenua sp. n. is in the shape of the

aedeagus very similar to N. pararubiginea and N. nan-

huaensis. Neoserica strenua differs from both by the

presence of a strong ventral subapical tooth at one fifth of

the aedeagal length.

Etymology. The name of the new species is derived from

the Latin adjective strenuus (busy) (adjective in the nom-

inative singular).

is aS narrow as the paramere and curved interiorly (dor-

sal view), while in N. dianae the parameres are straight

(lateral view) and the basal lobe is strongly widened and

straight (dorsal view).

Etymology. The new species is named after its type lo-

cality, Foping Nature Reserve (adjective in the nomina-

tive singular).

Diagnosis. Neoserica tianmushanica sp. n. 1s in shape

of the parameres very similar to N. fopingensis sp. n. It

differs from the latter in the shape of the parameres: they

are not slightly angled at the middle as in N. fopingensis

(lateral view), and the basal lobe of the right paramere is

widened at the apex and bent 90° to the main axis of the

paramere, while it is only in an angle of 45° to the main

paramere axis in N. fopingensis (dorsal view).

Etymology. The new species is named after its type lo-

cality, Tianmu Shan (adjective in the nominative singu-

lar).

Diagnosis. Neoserica (s.1.) anmaxinzhaiensis sp. n. dif-

fers from all other Neoserica species of China which

have the ventral posterior margin of metafemur smooth

in four characters: (1) by having a serrated longitudinal

line or carina beside the dorsal margin of the metatibia,

(2) by having the anterior two thirds of the frons shiny,

(3) by lacking a continuous serrated line beside the an-

terior margin of the metafemur, and (4) by having an

asymmetric aedeagus, with a long, lateral apophysis at

the right side of the phallobase.

Etymology. The new species is names after its type local-

ity, Anmaxinzhai (adjective in the nominative singular).

Aedeagus: Fig. 14I-K. Habitus: Fig. 14L.

Female unknown.

Diagnosis. Neoserica costisquamosa sp. n. differs from

all other known Neoserica species by the shape of the

aedeagus, the elytra bearing single scale-shaped setae,

and the metatibia being longitudinally convex along the

dorsal margin.

Etymology. The name of the new species (adjective in

the nominative singular) is derived from the combined

Latin words, costa (ridge) and squama (scale), with ref-

erence to the large scales on odd elytral intervals.

Aedeagus: Fig. 14A—C. Habitus: Fig. 14D.

Female unknown.

Diagnosis. This new species resembles in its habitus the

species of Neoserica (s. str.), however, several synapo-

morphies of this group are lacking, such as the serrated

line beside the dorsal margin of the metatibia, the double

pilosity of the dorsal surface, the reduced anterior angles

of the pronotum etc. From all other Chinese Neoserica

species N. gracilisetosa sp. n. differs by the dense pilos-

ity of the entire body.

Etymology. The name of the new species (adjective in

the nominative singular) is composed of the combined

Latin words gracilis (fine) and setosa (hairy, setose), with

reference to the fine, simple pilosity of dorsal surface.

Variation. Body length: 7.4-8.5 mm, length of elytra:

5.6-7.0 mm, width: 4.2—4.5 mm.

Ventral surface dull, partly shiny, finely and densely

punctate, with dense and fine, adpressed setae, metaster-

nal disc sparsely covered with longer setae; metacoxa

with a few longer setae laterally. Abdominal sternites

finely and densely punctate, glabrous, each sternite with

line, anterior row of setae complete; posterior ventral

margin smooth, moderately widened at ventral apex, dor-

sal posterior edge finely serrate, shortly densely setose.

Metatibia moderately long and wide, widest at middle,

ratio of width/ length: 1/2.8, sharply carinate dorsally,

with two groups of spines, basal group at middle, apical

group at three quarters of metatibial length, in basal half

gin; lateral face longitudinally convex, sparsely punc-

tate, widely glabrous along middle; ventral margin finely

serrate, with four equidistant robust setae; medial face

smooth and glabrous; apex finely serrate, shallowly sinu-

ate interiorly near tarsal articulation. Tarsomeres dorsally

impunctate, glabrous, neither laterally nor dorsally cari-

nate, moderately setose ventrally; metatarsomeres with

a strongly serrated ridge ventrally and a smooth subven-

tral longitudinal carina, ventrally glabrous; first metatar-

somere slightly longer than following tarsomere and little

shorter than dorsal tibial spur. Protibia moderately long,

bidentate; anterior claws symmetrical, basal tooth of both

claws bluntly truncate at apex.

Aedeagus: Fig. 18A—C. Habitus: Fig. 18D.

Remarks. The following paralectotypes could be iden-

tified as Maladera drescheri (Moser, 1913): 1 9 “Mu-

seum Paris Tonkin Sept. Ha-Lang Lamey 1904/ Serica

immutabilis (Gyll.) Fairm A.B. 1893/ 308” (MNHN),

1 2 “Museum Paris Tonkin Sept. Ha-Lang Lamey 1904/

Tonkin N. Ha-lang Lamey/ Serica immutabilis (Gyll.)

Fairm Ann. Bel. 1893 [308]” (MNHN). The lectotype is

virtually identical in the shape of its parameres with the

specimen from “Conchinchine” photographed in Fig. 18.

Due to the formal synonymy of Autoserica sensu aucto-

rum with Maladera Mulsant & Rey, 1871, the species has

been placed by Krajcik (2012) into Maladera. Due to its

multilamellate antenna we classify it here as a Neoserica

(sensu lato), although either idea might not be the defin-

itive solution for this species until the classification of

Sericini genera 1s finally resolved based on a robust phy-

logenetic tree comprising most major species lineages.

Remarks. My dear colleague, Paul Schoolmeesters in-

dicated to me recently a flaw that happened in Ahrens

(2003) leading to a primary homonymy between Neos-

erica (Ss. str.) vicina Ahrens, 2003 and Neoserica vicina

Moser, 1915. This is corrected here by a replacement

name, Neoserica schoolmeestersi Ahrens nom. n., for

the younger homonym, Neoserica vicina Ahrens, 2003

(which is due to the Code not available). The new name

is dedicated to Paul Schoolmeesters (Herent, Belgium).

Summary

This monograph represents the final part of the treatment of the Chi-

nese Neoserica (sensu lato) species which were part of the PhD the-

sis project of Wangang Liu. In this part, the taxonomy of the species

of the Neoserica major, N. uniformis, N. dianae, N. funiushanensis,

N. multifoliata species groups, as well as all other species incertae

sedis of Neoserica Brenske, 1894 is revised, while additional taxa

were discovered for the N. ca/va group. The study resulted in three

new combinations and the description of 39 new species trom Chi-

na. The lectotypes of two species are designated. The monograph

contains a key to the genera of Sericini with multilamellate anten-

nae, to species-groups of Neoserica trom mainland Asia, as well as

a key to the individual species of the species-groups examined here.

Species diagnostic characters and species distribution are illustrated.
