INTRODUCTION

The Indian subcontinent bears some of the world’s most

diverse regions. It encompasses a wide spectrum of eco-

zones, ranging from deserts to high mountains, highlands,

tropical and temperate forests, swamplands, plains, as well

as grasslands. The region includes several biodiversity

hotspots: the Western Ghats and Sri Lanka, the Himalayas

and the Tndo-Burmese’ region (Myers et al. 2000), which

are characterised by numerous endemic species.

The largest part lies within the Indo-Malayan (Orien¬

tal) realm, while the northern parts shape along the Hi¬

malayan range the boundary with the Palearctic region;

2000 to 2500 m are considered to be the altitudinal bound¬

ary between the Indo-Malayan and Palearctic zones (Mani

1974).

The climate is variable, although the entire Indian Sub¬

continent is heavily influenced by summer monsoons that

cause major seasonal changes in vegetation and habitat.

These patterns are reinforced by elevation and exposition

to rainfall.

Generally, information about the arthropods and beetles

of India is quite limited. Significant work having been

done only in a few groups of insects, notably select groups

of Lepidoptera, Odonata, Hymenoptera, Coleoptera and

Heteroptera. Most important concerted attempts to docu¬

ment the biodiversity have been made since the publica¬

tion of the series “The Fauna of British India, Including

Ceylon and Burma”, but most of these works date back

nearly 100 years or more. While for a number of scarab

beetles such volumes exist, in melolonthine chafers

(Melolonthinae) there has never been published such a

volume and therefore only fragmentary work since the first

taxonomic treatments of the Indian fauna exist (Fabricius

1775, Blanchard 1850, Burmeister 1855). Since then, on¬

ly a few authors contributed towards the knowledge in

Sericini, with major contributions given by Brenske

(1894-1902), Moser (1908-1920), Frey (1962a-1975b).

With nearly 4000 described species, Sericini chafers

(Coleoptera: Scarabaeidae) represent a very diverse tribe

of beetles with a nearly worldwide distribution only ab¬

sent in Australia and circumpolar regions (Ahrens 2006e).

Most extant species are found in a monophyletic lineage

(“modern Sericini”; Ahrens 2006e; Ahrens and Vogler

2008). It comprises two large palaeotropic subtribes, Seric-

ina and Trochalina, which number about 3000 species and

370 species, respectively. The phytophagous Sericini be¬

long to the lineage of Pleurostict chafers (Scarabaeidae),

which is thought to have greatly diversified with the rise

of angiosperms around 108 million years ago (Mya)

(Ahrens et al. 2014b). Compared to the soil dwelling lar¬

val stage, the lifetime of adults is short. The origin of

Sericini was proposed to be in Africa, because of the ex¬

clusively African distribution of Ablaberini, the sister

group of Sericini (Ahrens 2006e). The divergence of

Sericini from Ablaberini dates back to ca 100 Mya (Ahrens

et al. 2014b).

Our recent taxonomic work on the Indian fauna was

started by Ahrens (1995a, b) and was continued with a se¬

ries of papers and monographs on the fauna of the Hi¬

malayas and adjacent regions (Ahrens 1998a-2007c,

Ahrens & Fabrizi 2009a-2011, Liu et al. 2014a). Finally,

a first part of a comprehensive treatment of the fauna of

the Indian subcontinent was given by Fabrizi & Ahrens

(2014) who revised the Sericini fauna of Sri Lanka. This

monograph represents the second part of this revision sum¬

marising all available information on the Sericini fauna

of the Indian subcontinent.

MATERIAL AND METHODS

The principal terminologies (Fig. 1) and methods used for

measurements, specimen dissection and genital prepara¬

tion are described in detail in Ahrens (2004b, 2006e). The

examined material is cited with the original label contents

given in quotation marks, multiple labels are separated by

a “/”, additional comments are given in square brackets.

GPS coordinates are given for each newly sampled local¬

ity in Appendix 1, that of previously sampled ones may

be found in Ahrens (2004b) or in Fabrizi & Ahrens (2014),

or in the web (http://www.serica.gmxhome.de/layout05/

HimGazlNEW.htm). For each species, taxonomy was un¬

derpinned by a comprehensive list of synonymies and ref¬

erences (of faunistic, phylogenetic, and taxonomic treat¬

ments), however, in the latter, citations from pure taxo¬

nomic checklists (e.g., Dalla Torre 1912, Krajcik 2012)

were included only when this was crucial for a better un¬

derstanding of the taxonomic background of the species.

Male genitalia were glued to a small pointed card and

photographed in both lateral and dorsal view with a stere¬

omicroscope Olympus SZX-12 using a Jenoptik ProgRes

digital camera (C5 5.0), and at later stage, with a Leica

SM-125 and the digital camera DFC 420. Using AU¬

TOMONTAGE software a number of single-focused im¬

ages were combined to obtain an image that was in focus

throughout. The resulting images were subsequently dig¬

itally edited to remove the errors of the AUTOMONTAGE

reconstruction and to obtain a white background. A part

of the figures of male genitalia was done as pencil draw¬

ings (type material revised more than ten years ago) which

were subsequently graphically edited to obtain a black and

white image similar to a photograph.

Distribution maps were generated using QGIS 2.8.2.

based on the geographical coordinates. The same software

was also used to extract the ecoregion data for each species

based on the Terrestrial Ecoregion layer of World Wildlife

Fund and Nature Conservancy (2011; Olson et al. 2001).

Sericini of India

Chao diversity estimator (corrected) were calculated in DI-

VA-GIS v.5 (Hijmans et al. 2001). The similarity of the

species composition of ecoregions and that of the species

occurring in different ecoregions was calculated in PAST

v.3.1 (Hammer et al. 2001) using the neighbour-joining

method based on the Jaccard index (Jaccard 1902). For

the calculation of ecoregion-similarity regions with less

than three sampled species were excluded, and also a re¬

duced analysis on regions with complete sample investi¬

gation was performed.

Currently, most female specimens of Sericini are diffi¬

cult to identify (to genus and species), as diagnostic char¬

acters of genera, as defined currently, are often submit¬

ted to strong sexual dimorphism (e.g., the number of an-

tennomeres of club). Additionally, only the shape of aedea-

gus often offers sufficient, detailed and stable variation to

allow a discrimination of the species, while characters use¬

ful in other scarab groups, such as shape of the head and

pronotum or the punctuation and sculpture of the body sur¬

face, are often highly variable in Sericini. For the latter

reason, many species keys need to include genital char¬

acters as well, and a reliable identification of species is

impossible without examination of male genitalia.

Given the enormous diversity of Indian Sericini fauna,

this contribution was constrained by some editorial com¬

promises in order to save print space giving priority to

species that so far have not yet been revised and to those

that are new to science. Taxa that were treated previous¬

ly by the author(s), are referenced, included in the key, but

not described in detail nor illustrated.

Diagnosis. Serica feresegregata sp. n. is very similar to

S. segregata Arrow, 1946 and S. falcifera Ahrens & Fab¬

rizi, 2009 in its external and genital morphology. The new

taxon differs from the two previously mentioned species

in the slightly shorter antennal club, but significantly on¬

ly in the shape of the aedeagus: the dorsal lateral lamina

of the phallobase has interiorly a triangular lamella that

extends to the middle of the phallobase, in the former two

species this lamina is absent; furthermore, in S. fereseg¬

regata the dorsal lobe of the left paramere is nearly straight

but strongly widened, while it is narrower and bent ex¬

ternally at middle in the other two species.

Variation. Length: 8.8-9.6 mm, length of elytra: 7.2-7.3

mm, width: 5.0-5.9 mm.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the combined Latin words

fere- (nearly) and the species name ‘ segregata ’, with ref¬

erence to the similarity to S. segregata Arrow.

Distribution. So far known only from Arunachal Pradesh

(Fig. 40E).

Xenoserica Ahrens, 2005c: 273; (type species by original

designation: Nipponoserica sindhensis Ahrens, 2000);

Ahrens 2007c: 40.

Remarks. The genus was established by Ahrens (2005c)

in a follow-up of the results of a phylogenetic analysis

based on morphology. Recently, we were able to include

several taxa of Xenoserica into a major molecular phylo¬

genetic analysis including more than 600 Sericini species

from all over the World (Eberle et al. 2016). Results from

this analysis indicate that X. brachyptera is the sister tax¬

on to the species of the Serica erectosetosa group (Ahrens

2004b). Therefore, we transferred these species now to

Xenoserica.

Description. Length: 4.8 mm, length of elytra: 3.4 mm,

width: 3.0 mm. Body oblong, dorsal surface light brown,

frons and pronotum somewhat greenish, sides of elytra

darker, antenna yellowish, except shiny head dorsal sur¬

face dull, sparsely setose.

Labroclypeus widest shortly before base, lateral margins

moderately convex, anteriorly convergent to strongly

rounded anterior angles, lateral border and ocular canthus

producing a distinct blunt angle; margins weakly reflexed;

anterior margin shallowly sinuate medially; surface near¬

ly flat and shiny, finely and very densely punctate, dis¬

tance between punctures less than their diameter, with a

few coarser punctures behind anterior margin each bear¬

ing a long, erect seta; frontoclypeal suture feebly incised

and medially moderately curved; smooth area in front of

eye little wider than long; ocular canthus short and slen¬

der, finely and densely punctate, without terminal seta.

Frons shiny, only posteriorly narrowly dull, with fine,

dense punctures, glabrous except some erect setae beside

eyes. Eyes large, ratio of diameter/interocular width: 0.73.

Antenna yellow, with ten antennomeres; club dark, with

five antennomeres, 1.4 times as long as the remaining an¬

tennomeres combined. Mentum weakly elevated and flat¬

tened anteriorly.

Pronotum narrow, widest at base, lateral margins

straight and subparallel in basal half, in anterior half weak¬

ly curved and convergent anteriorly, anterior angles mod¬

erately produced and sharp, posterior angles blunt; ante¬

rior margin convexly produced medially, with a distinct

fine marginal line, basal margin without marginal line; an¬

terior and lateral margins sparsely setose; surface with

dense and fine punctures, except on disc with scattered

fine white short or moderately long setae in punctures, all

setae bent backwards; hypomeron distinctly carinate at

base but not ventrally produced. Scutellum narrow and

short, triangular, with sparse, fine punctures, on base me¬

dially smooth, punctures with microscopic setae.

Elytra moderately long, widest shortly at middle, stri¬

ae weakly impressed, finely and densely punctate; inter-

vals weakly convex, with fine and moderately dense punc¬

tures concentrated along striae, punctures with fine white

adjacent setae, odd intervals with a few single robust,

white, adjacent setae; interior apical angle of elytra with

a strong seta; epipleural edge fine ending at strongly

curved external apical angle of elytra; epipleura sparsely

setose, apical border without short microtrichomes.

Ventral surface dull, with fine and moderately dense

punctures, sparsely setose; metacoxa only laterally with

a few strong adjacent setae. Each abdominal sternite with

indistinct transverse row of coarse punctures bearing short

setae between fine, dense punctation, penultimate stern¬

ite apically with a shiny smooth sclerotised border, which

is one sixth as long as sternite, last sternite medially al¬

most half as long as penultimate one. Mesosternum be¬

tween mesocoxae as wide as mesofemur, with irregular¬

ly scattered very strong setae. Ratio of length of metepis-

temum/metacoxa: 1/1.5. Pygidium weakly convex, coarse¬

ly and densely punctate, with fine smooth midline, dull,

with numerous long setae.

Legs slender and moderately long; femora dull, with two

longitudinal rows of setae, finely and sparsely punctate;

metafemur shiny, sharply margined anteriorly and with¬

out a submarginal serrate line, posterior margin weakly

convex and glabrous, its external part only weakly

widened in apical half and not serrate, internally finely ser¬

rate, with short setae. Metatibia slender and moderately

long, uniformly widened toward apex, ratio width/length:

1/3.0, dorsally sharply carinate, with two groups of spines,

basal one shortly before middle, apical one at three quar¬

ters of metatibial length, basally with a few single, fine

setae; external face longitudinally convex, with sparse and

moderately coarse punctures, glabrous; ventral margin car¬

inate and serrate, with three strong spines, of which the

two distal are widely separated; internal face very finely

and sparsely punctate; apex interiorly near tarsal articu¬

lation sharply and deeply truncate. Tarsomeres dorsally

glabrous and impunctate, ventrally with sparse, short se¬

tae; metatarsomeres ventrally with a strongly serrate ridge,

beside which is a fine longitudinal carina; first metatar-

somere as long as following two tarsomeres combined and

twice as long as dorsal tibial spur. Protibia moderately

long, bidentate, protarsal claws symmetrical.

Aedeagus: Fig. 2E-H.

Variation. Length: 4.8—4.9 mm, length of elytra: 3.3-3.4

mm, width: 2.8-3.0 mm. Female: Antennal club composed

of three antennomeres, slightly shorter than remaining an-

tennomeres combined.

Diagnosis. Gynaecoserica etalinensis sp. n. is in the gen¬

eral shape of the parameres similar to G. lohitensis Ahrens

& Fabrizi, 2009, both sharing the basally strongly pro¬

duced parameres. G. etalinensis may be differentiated

from G. lohitensis by the antennal club being composed

of only five antennomeres (instead of six as in G. lohiten¬

sis), the slightly longer distal part of the parameres, and

the large lateral tooth on the left paramere which is en¬

tirely absent in G. lohitensis.

Etymology. The new species is named according to the

type locality Etalin (adjective in the nominative singular).

paramere is much shorter than the ventral one, the left

paramere is longer with the basal piece being less distinct¬

ly pronounced and shorter.

vergent with dorsal margin behind apical group of

spines, between serrated line and dorsal margin smooth

and glabrous; lateral face longitudinally convex, with a

few coarse punctures bearing each a long seta, along mid¬

dle smooth; ventral edge serrated, with four fine and long,

equidistant spines; medial face impunctate and glabrous;

ly and finely punctate and shortly setose in punctures; lat¬

eral face weakly longitudinally convex, with dense and

coarse punctures bearing each a short adpressed seta; ven¬

tral edge not serrated, with six robust and long, equidis¬

tant spines; medial face impunctate and glabrous; apex in¬

teriorly near tarsal articulation concavely sinuate. Tar-

Aedeagus: Fig. 2Q-S.

Diagnosis. The new species is very similar to A. argen-

tata (Frey), but differs by the slightly widened parameres,

which in A. argentata are narrowed towards the apex.

Variation. Length: 6.2-6.6 mm, length of elytra: 4.2-4.5

mm, width: 3.4-3.8 mm. The females are highly similar

to the males, there is no sexual dimorphism visible in the

length of the antennal club or the size of eyes.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the Latin adjec¬

tive Autulentus ’ (stained or dirtied with something).

Meriserica Brenske, 1897

Meriserica Brenske, 1897: 355 (type species by mono-

typy: Meriserica oberthuri Brenske, 1898).

Remarks. The distinction of Meriserica from Deroseri¬

ca Moser, 1915 is still uncertain due to the lack of a phy¬

logenetic analysis of the species. Both genera are rather

similar, main differences are the larger size of the body

and the insertion of parameres, which is in Deroserica

widely separated, while in Meriserica the insertion of both

parameres is displaced dorsally so that they are nearly

touching one another. Possibly, we find in Meriserica the

more derived state, that would result in a hypothesis that

Meriserica would be nested within the other Deroserica

species. However, until a more robust evidence from DNA

sequences is available we retain the separation of the two

genera.

veloped basal tooth.

Aedeagus: Fig. 2Aa-Ac. Habitus: Fig. 27F.

Diagnosis. Deroserica championi sp. n. is in its external

morphology and shape of male genitalia rather similar to

D. pulchra. D. championi differs from the latter by the

slightly shorter metacoxa, and in the shape of the para-

meres: the left paramere is not toothed at the external apex

while the right one has a well separated basal lobe.

Etymology. The new species is named after its collector,

H.G. Champion (noun in genitive case).

Variation. Length: 5.2-5.9 mm, length of elytra: 3.0-3.5

mm, width: 3.0-3.2 mm. Elytra in the paratype slightly

lighter, brown.

Aedeagus: Fig. 30-Q. Habitus: Fig. 27K.

Diagnosis. Anomioserica kotagiriensis sp. n. differs from

A. maesi by the darker body colour, the apical ventral mar¬

gin of mesotibia bearing very long and moderately dense

setae, the lacking of a short serrate line on basal metati¬

bia, and in the left paramere being straight.

Etymology. The new species is named ‘ kotagiriensis ’ ac¬

cording to the vicinity of type locality to Kotagiri (adjec¬

tive in the nominative singular).

Variation. Length: 3.9-5.0 mm, elytral length: 2.3-2.8

mm, width: 2.4-2.8 mm. The extension of the yellowish

part of the elytra may vary considerably. Female: Very

similar to the male, the basal tooth of anterior claw is nar¬

row, not as widened as in male.

Aedeagus: Fig. 3R-T. Habitus: Fig. 27L.

Remarks. The specimens from Trichinopoli are not clear¬

ly to identify as syntypes since in the original description

only “India (Madura)” is mentioned as type locality. There

is also no trace of the name “minuta ” previously used by

Moser to label the specimens. However, Moser (1916) in¬

dicated three specimens with completely dark elytra, of

which we could examine only one from Madura, but two

from Trichinopoli. This would mean that the specimens

could be in fact part of the original type series.

Diagnosis. The new species is rather similar in its exter¬

nal appearance to A. liliputana Moser. Anomioserica mae-

si sp. n. differs from the latter by the apex of mesotibia

having normal robust spines only (instead of fine and

dense ones in A. liliputana) and the left paramere being

hook-like curved interiorly (instead of straight like in A.

liliputana).

Etymology. We dedicate this new species to Jean Michel

Maes for his courtesy to provide us with these specimens

(noun in genitive case).

Variation. Length: 3.6-5.1 mm, elytral length: 2.5-3.1

mm, width: 2.4-2.9 mm. The colour varies from entirely

yellow to entirely dark brown, with variable extension of

the yellow part of the elytra. Female: generally larger;

basal inner protarsal claw narrow, simply pointed and not

as elongate as in male.

Aedeagus: Fig. 4J-L. Habitus: Fig. 28A. Female un¬

known.

Diagnosis. The species is quite similar to S. wilpattuen-

sis Fabrizi & Ahrens, 2014, from Sri Lanka, in the sum

of diagnostic features, however, it is larger, and its para-

meres are strongly curved externally.

Etymology. The new species is named after the Latin ad¬

jective ‘ vagans ’ (rambling) in reference to the distant oc¬

currence of the species from the diversity centre of Se-

laserica in Sri Lanka (adjective in the nominative singu¬

lar).

Distribution. See map (Fig. 45A).

Neoserica Brenske, 1894

Neoserica Brenske, 1894: 44 (type species by subsequent

designation: Serica ursina Brenske, 1894; Pope 1960);

Ahrens 2003c: 169, 2007c: 26; Liu et al. 2015a: 2379,

2015b: 346.

Remarks. Neoserica resulted polyphyletic in diverse mo¬

lecular phylogenies of Sericini (Ahrens & Vogler 2008;

Liu et al. 2015b; Eberle et al. 2016). The genus concept

needs to be revised based on a combined molecular and

morphological analysis but it needs a significantly wider

taxon sampling than so far available. Therefore, follow¬

ing Ahrens (2004) and Fabrizi & Ahrens (2014), we con¬

sider all species that were so far assigned to Neoserica and

that do not belong to the monophyletic Neoserica (sensu

stricto) group (Ahrens 2003b) preliminary as Neoserica

sensu lato.

Neoserica (s.str.) Brenske, 1894 group

Remarks. The Neoserica (s.str.) Brenske, 1894 group was

redefined by Ahrens (2003c) and studied in detail again

by Liu et al. (2015a). So far it is represented by only one

species on the Indian subcontinent, N. arunachalana

Diagnosis. Neosericapilistriata sp. n. is in its genital mor¬

phology rather similar to N. natmatoungensis Ahrens et

al., 2014, while both species differ strongly in their ex¬

ternal morphology: the parameres of N. pilistriata are

shorter and wider, the surface is more densely setose, and

the rim of microtrichomes at the apex of the elytra is ab¬

sent.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the combined Latin words,

‘pilus' (hair), and ‘ striatus ’ (striped), with reference to the

longitudinal rows of long setae on the elytra.

Variation. Length: 9.6-10.1 mm, length of elytra: 6.8-7.2

mm, width: 5.0-5.6 mm.

Aedeagus: Fig. 6J-L. Habitus: Fig. 29E.

Diagnosis. The new species differs from Neoserica in-

familaris sp. n. in the presence of only one lamina on the

ventral side of the phallobase, as well as in the stouter

parameres.

Etymology. The new species is named (adjective in the

nominative singular) with the Latin adjective ‘ plagiatus ’

(plagiarized) with reference to the highly similar taxon N.

infamilaris sp. n. to which N. plagiata seem to be a slight¬

ly modified copy.

Variation. Length: 10.5-11.8 mm, length of elytra:

7.2-7.7 mm, width: 6.2-6.6 mm. Female: body as in male;

antennal club composed of four antennomeres, 6^ anten-

nomere slightly transversely produced, club slightly

shorter than the remaining antennomeres combined; eyes

as large as in male.

Distribution. See map (Fig. 45C).

Aedeagus: Fig. 6M-0. Habitus: Fig. 29F.

Diagnosis. Neoserica ziyardamensis sp. n. is in external

shape and genital morphology rather similar to N. natma-

toungensis Ahrens et al., 2014. The species differs in the

left paramere being much shorter and strongly curved dor-

sally instead of ventrally (as in N. natmatoungensis ).

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

cality, Zi Yar Dam (= Ziyadam) (adjective in the nomina¬

tive singular).

Remarks. This species was omitted by our mistake from

the previous revision (Ahrens et al., 2014a), and is here

included along with the Indian species, although being

from Myanmar.

Distribution. Northern Myanmar, however, the type lo¬

cality was not located with GPS data, therefore the species

is not presented in our map (Fig. 45C).

Diagnosis. Neoserica ammattiensis sp. n. is in its male

genital morphology rather similar to N. flavoviridis but dif¬

fers from the latter by the antennal club being composed

of four instead three antennomeres, as well as in the api¬

cal metatibial spines which are in N. ammattiensis much

shorter than in N. flavoviridis. The apex of the right (ven¬

tral) paramere is more robust compared to that of N.

flavoviridis , the left paramere (dorsal) is shorter and slight¬

ly wider.

Etymology. This new species is named after its type lo¬

cality, Ammatti (adjective in the nominative singular).

Variation. Length: 5.1-5.6 mm, length of elytra: 3.9^1.5

mm, width: 3.3-3.8 mm. Colour may vary from above de¬

scribed pattern towards the body being entirely dark

brown. Female: Antennal club composed of three anten¬

nomeres, slightly shorter than remaining the anten¬

nomeres combined; eyes as large as in male.

Aedeagus: Fig. 7D-F. Habitus: Fig. 29K. Female un¬

known.

Diagnosis. Neoserica plateosa sp. n. differs from N.

Jlavoviridis and N. dichroa by the presence of a dorsal

process at the apex of its phallobase externally of the left

paramere; from N. dichroa it differs also by the antennal

club being composed of three antennomeres only.

Etymology. The species’ name (adjective in the nomina¬

tive singular) is derived from the Latin word ‘ plateosus ’

(rich with spots), with reference to the dark ornamenta¬

tion of the dorsal surface.

Variation. Length: 6.2-7.2 mm, length of elytra: 4.3-4.5

mm, width: 3.9-4.0 mm.

Diagnosis. Neoserica rotundotibialis sp. n. differs from

the similar N. dichroa sp. n. by the insertion of the left

paramere being displaced at its right side.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the combined

Latin words, ‘ rotundus ’ (round) and ‘ tibialis ’ (tibia), a

character related with the tibia (with reference to the lon¬

gitudinally strongly convex dorsal margin of the metati¬

bia).

Variation. Length: 5.2-5.8 mm, length of elytra: 3.8-3.9

mm, width: 3.1-3.5 mm. Female: club composed of three

antennomeres, straight, distinctly shorter than the remain¬

ing antennomeres combined, seventh antennomere not

transversely produced; eyes as large as in male.

Diagnosis. Neoserica submaculosa sp. n. differs from the

similar N. ammattiensis sp. n. by the long and straight left

apophysis of the phallobase.

Etymology. The name (adjective in the nominative sin¬

gular) of the new sepcies is derived from the combined

Latin words, 'sub- (prefix) (almost), and ‘ maculosa ’ (with

spots), with reference to the dorsal surface covered with

dark spots.

Variation. Length: 5.8-6.2 mm, length of elytra: 4.2^1.4

mm, width: 3.5 mm. Female: club composed of three an-

tennomeres, straight, distinctly shorter than the remain¬

ing antennomeres combined, seventh antennomere slight¬

ly transversely produced; eyes as large as in male.

riorly near tarsal articulation moderately sinuate. Tar-

someres ventrally with sparse, short setae, smooth, nei¬

ther laterally nor dorsally carinate; metatarsomeres with

a strongly serrated ridge ventrally, smooth, first metatar-

somere little shorter than the two following tarsomeres

Aedeagus: Fig. 4Q-T. Habitus: Figs 28D.

Diagnosis. The new species is more stout and robust than

all other species of the N. lubrica group. In the shape of

its genitalia it is most similar to N. pubiforceps Ahrens,

2004. From the latter, N. bicolorea sp. n. differs by the

bicoloured elytra, and the shape of the parameres: the sin-

utation of the left paramere is situated at the distal mar¬

gins in N. bicolorea , instead of at the lateral margin (as

in N. pubiforceps).

Etymology. The new species is named (adjective in the

nominative singular) with reference to its bicoloured ely¬

tra with the combined latin words, ‘ coloreus ’ (variegat¬

ed) and the prefix L bi- (twice).

Variation. Length: 6.2-6.5 mm, length of elytra: 4.2^1.6

mm, width: 37-3.9 mm. Elytra bicoloured, completely

light brown, or dark brown. Female: Antennal club com¬

posed of three antennomeres, club slightly shorter than the

remaining antennomeres combined.

Remarks. Paratypes are labelled as ‘ Neoserica bicolorata

sp. n.’ which was the name originally chosen for this

species. However, to avoid the name ‘bicolorata’ to be

used twice within Sericini (see Gynaecoserica bicolorata

Ahrens & Fabrizi, 2009) we decided to use and introduce

the name Neoserica bicolorea sp. n.

Aedeagus: Fig. 7P-R. Habitus: Fig. 290.

Diagnosis. Neoserica flagrans sp. n. differs from the rather

similar N. variegata Moser by the dull body surface and

the large scale-like setae on its elytra. From N. fusiforceps

sp. n. it differs by the well-separated parameres. In its gen¬

ital morphology N. flagrans sp. n. is very similar to N.

sparsa (Arrow, 1946) from Myanmar, however, the me¬

dian lobe of the left parameres is in the latter species

strongly widened at the apex.

Etymology. The name of the new species is derived from

the Latin word ‘ flagrans ’ (burning) (adjective in the nom¬

inative singular).

Diagnosis. Neoserica fusiforceps sp. n. differs from the

rather similar N. variegata Moser by the less shiny body

surface and the scale-like setae on its elytra, as well as in

the shape of the parameres being completely fused with

one another in the new species.

Etymology. The name of the new species (noun in appo¬

sition) is derived from the combined Latin words ‘ fusils’

(fused) and ‘ forceps’ (forceps), with reference to the para¬

meres being fused with the aedeagus.

Diagnosis. N. keralana sp. n. differs from the very simi¬

lar N. multijlabellata Moser by the left paramere being

wider and the ventral phallobasal process being shorter.

Etymology. The new species is named according to its oc¬

currence in Kerala state (adjective in the nominative sin¬

gular).

Type material examined. Holotype “India Madura/

Neoserica madurana Type Mos.” (ZMHB).

Remarks. The only known syntype preserved in the col¬

lection of Moser (ZMHB) is after (presumable) dermestid

damage completely destroyed, only the aedeagus is pre¬

served. There was no additional material available to des¬

ignate a neotype. Therefore, it was not possible to provide

a redescription of the species and to include it in the iden¬

tification key.

The original description translated from German (Moser

1915a: 167):

“Dull, dorsal surface dark reddish brown, ventral sur¬

face light brown. Head sparsely setose, frons with fine

punctures. [LabrojClypeus rugosely punctate, slightly con¬

vex at middle, only slightly anteriorly narrowed, anterior

red-yellowish, with ten antennomeres, club in male with

four antennomeres, shorter than the remaining anten¬

nomeres combined, 5^ antennomere with spines. Prono-

tum with fine, minutely setose and moderately dense punc¬

tures, anterior margin weakly convex, setose as lateral

margins. Lateral margins behind middle slightly concave,

anteriorly convexly convergent. Sharp anterior angles pro¬

duced, blunt posterior angles weakly rounded at tip. Ely¬

Aedeagus: Fig. 9D-F. Habitus: Fig. 30J.

Diagnosis. The new species is very similar to “ Aserica

major Arrow, 1946” from Myanmar which formally also

belongs to Neoserica sensu lato, but it will be revised in

a separate paper. N. pseudomajor differs in the slightly

shorter antennal club and the shape of aedeagus: the dis¬

tal portion of the phallobase is narrower and not that

broadly pronounced as in A. major ; the distal lateral mem¬

braneous slit is in A. major distinctly longer than in N.

pseudomajor.

Etymology. The species’ name (adjective in the nomina¬

tive singular) is composed by the Greek prefix ‘ pseudo ’

(false) and the species name ‘ major ’ (greater), with ref¬

erence to its similarity to Aserica major.

Variation. Length: 8.8-10.0 mm, length of elytra: 6.2-6.9

mm, width: 5.3-5.8 mm. Female: Eyes slightly smaller

than in male, antennal club short, composed by three an¬

tennomeres.

Remarks. The male genitalia of the types of both species

are virtually identical in shape, consequently, M. chilken¬

sis is to be considered a junior synonym of N. quadril-

amellata. The length of the sixth antennomere is variable,

in most specimens the antennal club appears to be com¬

posed of five antennomeres with the first joint of club half

as long as the club.

ther laterally nor dorsally carinate, sparsely setose ventral¬

ly; metatarsomeres with a strongly serrated ridge ventral¬

ly and a smooth subventral longitudinal carina; first

spur. Protibia short, bidentate; anterior claws symmetri¬

cal, basal tooth of both claws bluntly truncate at apex.

Aedeagus: Fig. 9V-Y. Habitus: Fig. 3ON.

Diagnosis. Neoserica sforziae sp. n. differs from the most

similar N. rajasthanica sp. n. and N. pushkarensis sp. n.

by the smaller body, the shiny ventral surface and by the

shape of aedeagus.

Etymology. The new species is named after one of its col¬

lectors, Alessandra Sforzi (noun in genitive case).

metrical, feebly curved and long, with normally developed

and simply pointed basal tooth.

Aedeagus: Fig. 10A-D. Habitus Fig. 300.

Diagnosis. This new species is very similar to N. setig-

era (Brenske). Neoserica subsetosa sp. n. differs princi¬

pally by the shape of right paramere being (in lateral view)

extended at its apex and dorsally strongly curved, instead

of being deeply sinuate at its apex like in N. setigera.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the combined Latin prefix

‘ sub- (almost) and ‘setostf (setose).

Variation. Length: 5.8-7.8 mm, elytral length: 4.3-5.4

mm, width: 3.3-4.1 mm. Female: Antennal club composed

of five antennomeres, as long as remaining antennomeres

combined.

designation: Neoserica gestroi Brenske, 1898); Ahrens

2007c: 38; Liu etal. 2014c: 83.

Remarks. So far 37 species have been formally assigned

to Tetraserica (Ahrens 2004b, Ahrens and Fabrizi 2009b,

Liu et al. 2014c). All other oriental species (so far grouped

with “ Neoserica ”) that potentially belong to Tetraserica

species await taxonomic revision. Tetraserica differs from

the two closely related genera Microserica Brenske, 1894

and Trioserica Moser, 1922 by the lack of a ventral cari¬

na on the hypomeron. From Microserica Tetraserica al¬

so differs by the lacking sexual dimorphism of the pygid¬

ium, from Trioserica by the bidentate protibia. In contrast

to Microserica , species of Tetraserica are active at night

and are attracted to light.

Distribution. The genus is distributed almost in the en¬

tire Oriental region; we know described species so far as¬

signed to “ Neoserica ” from Philippines, Indochina,

Sumatra, Borneo, and China (Ahrens 2004b; Liu et al.

2014c). Except for Meghalaya and the Himalaya, the

genus does not occur on the Indian subcontinent south of

the Ganges.

Etymology. The new species is named with the Latin ad¬

jective, ‘ impar’{ unequal), with reference to being differ¬

ent to its relative T. miniatula (adjective in the nomina¬

tive singular).

Aedeagus: Fig. 10K-M. Habitus: Fig. 31E. Female un¬

known.

Diagnosis. Tetraserica rufimargo sp. n. resembles in ex¬

ternal appearance and genital morphology somewhat T.

ferrugata (Blanchard). T. rufimargo sp. n. differs, how¬

ever, by the first segment of the antennal club being sube¬

qual in length with the club, and the shape of the para-

meres: the left paramere is apically not sharply pointed,

the right paramere possesses instead of the hook-like basal

lobe multiple spikes, its ventral lobe is wider and round¬

ed at apex.

Etymology. The name (noun in apposition) of the new

species is derived from the combined Latin adjectives, ‘ ru-

fus' (red) and ‘ margo 5 (margin), with reference to the red¬

dish margin of the pronotum.

Variation. Length: 6.9-8.0 mm, length of elytra: 4.9-5.5

mm, width: 4.5-4.9 mm.

Diagnosis. Tetraserica univestris sp. n. is very similar in

the shape of the parameres to T. impar; however, the dor¬

sal lobe of the left paramere is reduced and the distal me¬

dian process of the phallobase is exceeding distinctly the

ventral lobe of the right paramere. Furthermore, T. uni¬

vestris differs by the longer metatibia.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the Latin adjec¬

tive, ‘ univestris ’ (concordant), with reference to strong

similarity among the Tetraserica species’ external mor¬

phology.

Distribution. See map (Fig. 46D).

Remarks. The genus differs from Tetraserica by the body

colour being yellowish brown with often dense but dark

spots of variable size, the antennal club in male having

four or five antennomeres, the prothorax having a basal¬

ly carinate hypomeron, as well as the protibia being tri-

dentate.

Aedeagus: Fig. 10X-Z. Habitus: Fig. 310. Female un¬

known.

Diagnosis. The new species belongs to the Microserica

varians group. It differs from the similar species M. do-

hertyi Ahrens & Fabrizi, 2009 and M. varians Moser, 1915

by the phallobase that has ventrally on each side an ele¬

vated carina. In the other species of this group the elevat¬

ed carina is present only on the left side.

Etymology. The new species in named after its type lo¬

cality, Roing (adjective in the nominative singular).

Distribution. India, Arunachal Pradesh (Fig. 46E).

Autoserica auctorum (nee Brenske, 1897).

Remarks. Since Reitter (1896) and then Pope (1960) the

status of the genus Maladera is under debate, along its as¬

sociated synonyms and subgenera. Recent works of

Ahrens & Vogler (2008) and Liu et al. (2015b) have shown

that Maladera as a genus defined by the currently includ¬

ed taxa (most of the species described under Autoserica

[auctorum] by Brenske, Moser, and Frey) is polyphylet-

ic.

According to the formal synonymy of Maladera Mul¬

sant & Rey, 1871 with Autoserica auctorum (nee Brenske,

1897) (see Ahrens 2004b), taxa described under the genus

nam q Autoserica should be transferred to Maladera. New

combinations that were not validly published so far ac¬

cording to the Code of Zoological Nomenclature (e.g., in

online databases or species checklists; e.g., Schoolmeis-

ters 2016) are treated here as such (i.e., ‘new’) and are re¬

ferred therefore in the text with “comb. n”. However, most

of the taxa were covered by the rather incomplete self-pub-

lished checklist of Krajcik (2012) and are not again

marked as new combinations.

Aedeagus: Fig. 11D-F. Habitus: Fig. 32D.

Diagnosis. Maladera xanthoptera sp. n. differs from the

most similar M. satrapa by the shape of the aedeagus: the

apex of the parameres is deeply sinuate, in lateral view

the parameres are much narrower in the new species.

Etymology. The name (noun in apposition) of the new

species is derived from the combined latinised Greek

words ‘ xanthos ’ (yellow) and ‘ pteron ’ (wing), with refer¬

ence to the yellow elytra.

Variation. Length: 5.8-6.1 mm, length of elytra: 3.5—4.1

mm, width: 3.5-4.1 mm. Female: Body slightly larger,

head and pronotum reddish brown. Antennal club with

three antennomeres and straight, distinctly shorter than the

remaining antennomeres combined.

Distribution. See map (Fig. 47B).

Aedeagus: Fig. 11G-I. Habitus: Fig. 32E. Female un¬

known.

Diagnosis. Maladera hunliensis sp. n. is in its shape of

the aedeagus very similar to Maladera mussooriensis

Ahrens, 2004, but the lateral apophysis of its phallobase

is narrower, being entirely displaced laterally, and the

fused parameres are combined distinctly narrower in dor¬

sal view.

Etymology. The new species is named with reference to

its type locality, Hunli (adjective in the nominative sin¬

gular).

Ventral surface coarsely and densely punctate, with mi¬

croscopic setae in punctures, with a few longer setae on

mesosternum and metasternal plate. Mesosternum be¬

tween mesocoxae 1.5 times as wide as mesofemur. Ratio

of length of metepisternum/metacoxa: 1/1.78. Metacoxa

glabrous, laterally with a few robust setae. Abdominal ster-

nites finely and moderately densely punctate, with a trans¬

verse row of coarse punctures each bearing a robust seta,

penultimate sternite with a very narrow shiny chitinous

rim. Pygidium shiny, weakly convex, coarsely and dense¬

ly punctate, without median impunctate line, with a few

fine longer setae apically, otherwise only with microscop¬

ic setae only.

Legs moderately wide; femora with two longitudinal

rows of setae. Metafemur shiny, superficially punctate, an¬

terior edge acute, with adjacent serrated line, which is un¬

dulated and partly interrupted, anterior row of setae com¬

plete but its setae very short; posterior ventral margin al¬

most straight, weakly widened in apical half, neither ven-

trally nor dorsally serrated but smooth, glabrous. Metat¬

ibia wide and short, widest at middle, ratio width/length:

1/2.2, sharply carinate dorsally, with two groups of spines,

basal one shortly before middle, apical one at three quar¬

ters of metatibial length, in basal third with 3-4 coarse

punctures each bearing a robust seta; lateral face weakly

longitudinally convex, impunctate, only ventral part with

moderately dense and coarse punctures; ventral margin

with four equidistant spines; medial face impunctate and

glabrous, apex shallowly sinuate interiorly near tarsal ar¬

ticulation. Tarsomeres impunctate dorsally, circular in

cross section, with sparse, fine setae ventrally; metatar-

someres ventrally with a strongly serrated carina, subven-

trally with a second, smooth longitudinal carina; first

metatarsomere distinctly shorter than following two tar¬

someres combined and little longer than dorsal tibial spur.

Protibia moderately long, bidentate, teeth moderately

large. All claws symmetrical, feebly curved and long, with

normally developed basal tooth.

Aedeagus: Fig. 11J-L. Habitus: Fig. 32G.

Diagnosis. Due to the presence of a presumably motile

dorsal lobe of the left paramere Maladera nigrolucida sp.

n. resembles somewhat the species of the M. lugubris

group. It differs from them by the body being complete¬

ly shiny and having a lamina-like dorsal process at the

apex of the phallobase that covers the base of the para-

meres.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the combined

Latin words ‘ nigris ’ (black) and 7 ucidus’ (shiny), with ref¬

erence to the black and shiny dorsal surface.

Variation. Length: 9.2-9.7 mm, elytral length: 6.4-6.7

mm, width: 5.6-5.9 mm. Female: No apparent sexual di¬

morphism, only the antennal club slightly shorter than in

male.

known.

Diagnosis. Maladera namborensis sp. n. is in its external

morphology very similar to M. sempiterna. The new

species differs from the latter by the distinctly asymmet¬

ric parameres, the right paramere being half as long as the

left one. From all other species of the M. ferruginea group

M. namborensis can be distinguished by the lateral

apophyses at each side of phallobase.

Etymology. This new species is named after the Nambor

forest reserve in Assam (adjective in the nominative sin¬

gular).

Distribution. See map (Fig. 47D).

parameres are still recognisable although being fused with

the phallobase. The species differs form all other Indian

Maladera species by the elevated coarse punctures at odd

Etymology. The species name is derived from the Latin

word ‘ granigerus ’ (bearing small tubercles) (adjective in

the nominative singular).

an indistinct angle, anterior angles strongly convex, an¬

terior margin shallowly sinuate medially, margins weak¬

ly reflexed; surface shiny, at base narrowly dull, weakly

convex medially, densely and finely punctate, distance be¬

tween punctures partly smaller their diameter, with a few

single setae anteriorly; frontoclypeal suture finely incised,

bluntly angled medially; ocular canthus moderately wide

gins evenly convex and convergent anteriorly, slightly nar¬

rowed towards strongly rounded posterior angles, anteri¬

or angles sharp and distinctly produced; anterior margin

with a fine marginal line, weakly convexly produced me¬

dially; basal margin without marginal line; surface fine¬

ly and evenly densely punctate, setae of lateral and ante¬

rior margin robust but sparse, punctures with microscop¬

ic setae only. Scutellum wide, triangular, punctation as in

claws symmetrical.

Aedeagus: Fig. 12G-I. Habitus: Fig. 32M.

Diagnosis. Maladera profana sp. n. differs from all oth¬

er species of the M. granuligera group by the lack of an

apical apophysis of the phallobase as well as in the pres¬

ence of a short basal lobe on each paramere.

Variation. Length: 10.6-12.2 mm, elytral length: 7.8-8.8

mm, width: 6.7-7.5 mm. Female: Antennal club as long

as the remaining antennomeres combined; eyes smaller

than in male: ratio diameter/ interocular width: 0.51.

Etymology. This new species is named from the Latin ad¬

jective ‘ profanus ’ (non sacred) (adjective in the nomina¬

tive singular).

ly densely and finely punctate, glabrous, neither lateral¬

ly nor dorsally carinate, moderately setose ventrally;

metatarsomeres with a strongly serrated ridge ventrally

ly long, bidentate; anterior claws symmetrical, basal tooth

of both claws bluntly truncate at apex.

Aedeagus: Fig. 12M-0. Habitus: Fig. 32P. Female un¬

known.

Diagnosis. Maladera declarata sp. n. is in the shape of

the genitalia and in its external morphology similar to M

minops. The new species differs from M. minops by the

lacking ventral teeth of the apical phallobase (in lateral

view), the presence of a symmetric dorsal phallobasal

process that is deeply incised, and in the apically strong¬

ly dilated parameres.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the Latin adjec¬

tive ‘ declaratus' (declared), with reference to its impres¬

sive differences in the aedeagus from the other species of

the group.

Variation. Length: 7.5-8.0 mm, length of elytra: 5.6-5.9

mm, width: 4, 4-4 .5 mm.

Aedeagus: Fig. 12P-R. Habitus: Fig. 33A.

Diagnosis. Maladera decolor sp. n. differs from the taxa

of the M. sikkimensis group by its larger body size and the

short antennal club, from somewhat similar taxa of the M.

indica group it differs by the smooth and not serrated dor¬

sal posterior margin of the metafemur.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the Latin adjective ‘ decol¬

or ’ (discoloured) with reference to its variable and poly¬

morphic colour, which is sometimes lost.

Variation. Length: 9.6-10.2 mm, length of elytra: 6.5-7.2

mm, width: 6.0-6.1 mm. Colour very variable: entirely

reddish brown, or reddish brown with dark brown elytra,

in the latter condition there can be larger light spots on

elytra too. Female: antennal club with three antennomeres,

slightly shorter than the remaining antennomeres com¬

bined.

Distribution. See map (Fig. 48A).

meres that are at the apex more strongly rounded.

Etymology. The new species is named in honour of its col¬

lector, G.F. Hampson (noun in genitive case).

Remarks. The designation of the lectotype of Maladera

indica by Frey is not valid, as it was not published. The

tiny lateral tooth of the parameres as well as the length of

the interior lobe of the parameres are quite variable in

shape, while the external body shape, the shape and punc-

tation of the labroclypeus, as well as the metatibia are all

identical among the syntypes of the three species. The

shape of the aedeagus is quite variable, too, and does not

correlate with the length of antennal club as encountered

in the type specimens of nilgiriensis , indica, und

laminipes. The genitalia of the male syntypes of Autos er¬

ica singular is, probably dissected by Frey, are virtually

identical in shape with those of Maladera indica (Blan¬

chard) and d utoserica laminipes Moser, although anten¬

nal clubs of this form (A. singularis) are only as long as

the remaining antennomeres. There is no geographic dif¬

ferentiation and many intermediate forms for the length

of antennal club, thus we conclude that club lengths rep¬

resents intraspecific variation. The same uncertainty lies

in the ratio of the length of the interior lobes of the para¬

meres in relation to the length of the parameres: accord¬

ing to current observations, they seem to be slightly short¬

er in specimens with longer antennal club, however, there

is a wide overlap between the forms and thus a differen¬

tiation based on their morphology is impossible. We there-

sularis , M. declarata , and M. minops. M. sedula differs

from the latter three by the longer antennal club, as well

as in the shape of the aedeagus and in the absence of a

dorsal or ventral phallobasal apophysis.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the Latin adjec¬

tive ‘ sedulus ’ (busy).

Aedeagus: Fig. 13M-0. Habitus: Fig. 33G. Female un¬

known.

Diagnosis. This new species is in its external shape rather

similar to most species of the M. lugubris group, howev¬

er, the serrated line adjacent to the anterior margin of

metafemur, a key feature of species belonging to the lat¬

ter group, is not continuous in M. initialis sp. n.. The apex

of phallobase and the insertion of parameres is strongly

asymmetric, and the labroclypeus is narrower.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the Latin word ‘ initialis ’ (ini¬

tial, the first).

Distribution. See map (Fig. 48C).

of both claws bluntly truncate at apex.

Aedeagus: Fig. 13P-R. Habitus: Fig. 33H.

Diagnosis. This new species is in the shape of aedeagus

very similar to M. significans (Brenske). M. mysoreensis

differs from the latter in having a broader aedeagus with

nearly symmetrical parameres. In addition, the lateral lam¬

ina of the ventral phallobase (right side) is in M.

mysoreensis higher than in M significans.

Etymology. The new species is named with reference to

its occurrence in Mysore (adjective in nominative sing.).

Variation. Length: 8.1-9.8 mm, length of elytra: 6.0-6.9

mm, width: 5.4-6.0 mm. Female: Antennal club slightly

shorter than in male.

Aedeagus: Fig. 14D-F. Habitus: Fig. 33M. Female un¬

known.

Diagnosis. This species is in the shape of the aedeagus

very similar to M. lugubris but it differs in having the dor¬

sal process of the right paramere reduced; in addition the

parameres of M. rudimentalis are distinctly wider (in lat¬

eral view).

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the Latin word ‘ rudimen -

tabs' (rudimentary), with reference to the reduced dorsal

process of the right paramere.

Variation. Length: 7.6-9.9 mm, length of elytra: 5.9-7.4

mm, width: 4.8-6.1 mm. Female: Antennal club distinct¬

ly shorter than the remaining antennomeres combined;

eyes as large as in male; pygidium less convex.

Aedeagus: Fig. 140-Q. Habitus: Fig. 33P. Female un¬

known.

Diagnosis. The species differs from all other taxa of the

M. lugubris group by having an elongated and tubular

phallobase.

Etymology. The name of the new species (adjective in the

nominative singular) is derived from the Latin word ‘ tubu-

latus ’ (with a tube), with reference to the tubular shape

of the phallobase of aedeagus.

Variation. Length: 6.1-6.4 mm, length of elytra: 3.9—4.3

mm, width: 3.5-3.9 mm.

Diagnosis. The new species is very similar in external ap¬

pearance to M. constans sp. n. Maladera amboliensis sp.

n. differs from the latter in the large right paramere which

is not flattened and is lacking a terminal hook, as well as

in the median lobe of phallobase which is very short.

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

cality, Amboli (adjective in the nominative singular).

Variation. Length: 7.4-7.7 mm, length of elytra: 5.0-5.3

mm, width: 42-AA mm. Female: antenna with ten anten-

nomeres; club with three antennomeres and straight, dis¬

tinctly shorter than remaining antennomeres combined;

metatarsomeres with a strongly serrated ridge ventrally

and a smooth subventral longitudinal carina; first metatar-

somere as long as following two tarsomeres combined and

as long as dorsal tibial spur.

Distribution/ Remarks. The GPS coordinates of the type

locality Amboli are given incorrectly on the original la¬

bels: it is in fact: 15.97N, 73.98E (Fig. 48E).

Aedeagus: Fig. 150-R. Habitus: Fig. 34E.

Diagnosis. Maladera anaimalaiensis sp. n. is very simi¬

lar to M. mussardi sp. n. but differs in the distinctly wider

median phallobasal lobe that is distally before the apex

slightly enlarged, instead of being evenly narrowed to¬

wards the apex as in M. mussardi.

Etymology. The new species is named after its occurrence

in the Anaimalai Hills (adjective in the nominative sin¬

gular).

tate; anterior claws symmetrical, basal tooth of both claws

bluntly truncate at apex.

Aedeagus: Fig. 15S-U. Habitus: Fig. 34F.

Diagnosis. Maladera andrewesi sp. n. differs from all oth¬

er species of the M. marginella group by the strongly shiny

surface, the slender legs with the metatibia reaching their

widest point apically, and the metatarsomeres being ven-

trally densely setose.

Etymology. The new species is named after one of its col¬

lector, Henry L. Andrewes (noun in genitive case).

Variation. Length: 9.8-10.6 mm, length of elytra: 7.5-7.6

mm, width: 5.9-6.6 mm. Female: antennal club slightly

shorter than in male; pygidium flat.

Distribution. See map (Fig. 48E).

Remarks. The syntypes of M. burmeisteri represent an

intermediate form between a northern form (populations

of Jabalpur) and a southern form, which represents

Maladera burmeisteri ssp. alternans (Frey, 1975). Cur¬

rently the name of M. burmeisteri is referred to the north¬

ern form, however, further investigations are necessary to

Remarks. The name Autoserica sericina Frey, 1972 is

preoccupied by Autoserica sericina Moser, 1916 from

Kamerun. Due to primary homonymy and secondary

homonymy with this taxon (because of the synynomy of

Autoserica auctorum with Maladera ; i.e. Maladera seric¬

ina (Moser, 1916) comb, n.) we had to provide Autoser¬

ica sericina Frey, 1972 with a replacement name:

Maladera eusericina. M. eusericina differs as follows

from M. sericella Brenske: the sclerotised portion of the

filiform endophallus is extended beyond the right para-

mere in M. eusericina , ventrally it bears dense and long

setae.

Aedeagus: Fig. 16V-X. Habitus: Fig. 34N. Female un¬

known.

Diagnosis. Maladera fastuosa sp. n. is in its external mor¬

phology most similar to M. nigromicans (Frey). It differs

from the latter by the more trapezoidal labroclypeus, the

narrower apical membraneous rim of the elytra, as well

as in the shape of aedeagus: the right apical phallobasal

apodeme is strongly produced and much longer than the

short one of M. nigromicans ; the median lobe between the

parameres is also strongly elongated.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the Latin word

‘ fastuosus ’ (haughty), with reference to the dark shiny

body that is distinctive from most other Indian Sericini.

Variation. Length: 9.6-9.8 mm, length of elytra: 6.5-6.9

mm, width: 5.8-6.1 mm.

Aedeagus: Fig. 16Y-Aa. Habitus: Fig. 340.

Diagnosis. Maladera ferekanarana sp. n. is in the shape

of its external morphology and male genitalia very simi¬

lar to M. kanarana. The right phallobasal apodeme that

bears the right paramere is in the new species distinctly

shorter than in M. kanarana , while the median distal

process between the two parameres is distinctly wider. In

contrast, M. kanarana has the labroclypeus nearly semi¬

circular and has larger eyes.

Etymology. The species name is derived from the Latin

word, ‘ fere ’ (almost/ about) and "kanarana' , with refer¬

ence to the strong similarity to the previous species, M.

kanarana (adjective in the nominative singular).

Variation. Length: 9.6-11.5 mm, length of elytra: 6.4-7.2

mm, width: 5.5-6.6 mm. Female. Antennal club distinct¬

ly shorter than remaining antennomeres combined, eyes

as large as in male. The specimens of the populations of

Maharashtra are more shiny and slightly larger but in the

shape of the aedeagus both are entirely identical.

Aedeagus: Fig. 17A-C. Habitus: Fig. 34P.

Diagnosis. The species is very similar in the shape of its

aedeagus to M. nigromicans Frey, it may be distinguished

from the latter by the shorter and wider metatibia, as well

as the surface of the labroclypeus, which is slightly con¬

vex centrally. From M. ferekanarana sp. n. M. garoana

can be distinguished by the broader median phallobasal

lobe (ca 1/2 of max. width of phallobase in dorsal view)

and the right paramere being short and more strongly re-

flexed.

moderately dense punctures concentrated along the stri¬

ae and with minute setae in punctures, odd intervals with

short single setae; epipleural edge robust, ending at con¬

vexly rounded external apical angle of elytra, epipleura

Aedeagus: Fig. 18D-G. Habitus: Fig. 35J.

Diagnosis. Maladera padaviyaensis sp. n. is in its exter¬

nal morphology and its male genital shape most similar

to M. poonmudi (Frey). The new species differs from the

latter in the more convex elytral intervals, the nearly semi¬

circular labroclypeus, and in the shape of the aedeagus:

the right distal phallobasal apodeme is slightly shorter but

not convexly dilated at its dorsal margin; the right para-

mere is more evenly curved; a character shared with M.

poonmudi is the sharply pointed distal hook.

Etymology. The new species is named with reference to

its type locality, Padaviya (adjective in the nominative sin¬

gular).

Distribution. See map (Fig. 48E).

Etymology. The species name (noun in apposition) is de¬

rived from the Latin word ‘ sagittulus ’ (a small arrow), with

reference to the shape of the apex of the right paramere.

Variation. Length: 8.1-9.0 mm, length of elytra: 6.0-6.5

to M pauper sp. n. and M. sagittula sp. n. The new species

differs from both of the latter in the right apical phallobasal

apodeme being one phallobasal width longer than the left

one.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from the combined Latin prefix

‘sub -’ (almost) and the adjective ‘ mucronatus ’ (sharp/

pointed), with reference to the triangular shape of the apex

of the right paramere.

Variation. Length: 7.5-8.2 mm, length of elytra: 5.4-5.7

mm, width: 4.2^1.7 mm. Colour uniform, dark to reddish

brown. Antenna with ten antennomeres; club with three

antennomeres and straight, distinctly shorter than remain¬

ing antennomeres combined. First metatarsomere slight¬

ly shorter than following two tarsomeres combined and

slightly longer than dorsal tibial spur.

Aedeagus: Fig. 19A-C. Habitus: Fig. 36C.

Diagnosis. Maladera dimidiata sp. n. is in shape of aedea¬

gus rather similar to M. kallarensis sp. n. The new species

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

paramere has a large lateral lobe being half as long as the

distal lobe, the lateral lobe in M. kallarensis is much short¬

er.

Etymology. The species name (adjective in the nomina¬

tive singular) is derived from Latin word ‘ dimidiatus ’ (sep¬

arated in two pieces), with reference to the right paramere

being divided into two lobes.

nites finely and moderately densely punctate, with a trans¬

verse row of coarse punctures each bearing a robust seta,

penultimate sternite with a very narrow shiny chitinous

rim. Pygidium dull, weakly convex, finely and moderate¬

ly densely punctate, with narrow impunctate median line,

someres combined and slightly longer than dorsal tibial

spur. Protibia moderately long, bidentate, teeth moderate¬

ly large. All claws symmetrical, feebly curved and long,

with normally developed basal tooth.

Aedeagus: Fig. 19D-F. Habitus: Fig. 36D.

Diagnosis. Maladera kallarensis sp. n. is in the shape of

its aedeagus rather similar to M. placida (Frey). The new

species differs from the latter by the lack of a serrated line

laterally of the anterior margin of the metafemur, as well

as in the shape of its parameres: the right paramere has a

large lateral lobe, the left lateral phallobasal apodeme ex¬

ceeds the insertion point of left paramere.

Etymology. The new species is name with reference to

its occurrence in the Kallar valley (adjective in the nom¬

inative singular).

Variation. Length: 9.4-10.9 mm, elytral length: 6.7-7.3

mm, width: 6.6-6.8 mm. Female: Antennal club slightly

shorter than in male.

Diagnosis. Maladera sylhetensis sp. n. is in its external

morphology and in the shape of the aedeagus very simi¬

lar to M. allopruinosa (Ahrens), but in the new species

the dorsal process of its phallobase is abruptly narrowed

basally and evenly narrow over its entire length towards

the apex.

Etymology. The name of the new species is derived from

its type locality, Sylhet (Bangladesh) (adjective in the

nominative singular).

tae in punctures; epipleural edge ending at external api¬

cal angle of elytra; epipleura with long and sparse setae;

apical margin with a broad membranous rim of fine mi-

crotrichomes.

Ventral surface coarsely and densely punctate, with mi¬

croscopic setae in punctures, with a few longer setae on

mesosternum and metasternal plate. Mesosternum be¬

tween mesocoxae as wide as mesofemur. Ratio of length

of metepisternum/metacoxa: 1/1.42. Metacoxa glabrous,

sternite with dense and long setae. Pygidium dull, mod¬

erately convex, coarsely and densely punctate, with fine

long setae on apical half, otherwise with microscopic se¬

tae in punctures.

Legs moderately wide; femora with two longitudinal

terior edge acute, with adjacent serrated line, which is

straight and complete, anterior row of setae present but

its setae short; posterior ventral margin almost straight,

weakly widened in apical half, neither ventrally nor dor-

sally serrated but smooth, glabrous. Metatibia moderate¬

ly wide and short, widest shortly before apex, ratio

ly large. All claws symmetrical, feebly curved and long,

with normally developed basal tooth.

Aedeagus: Fig. 19M-0. Habitus: Fig. 36H. Female un¬

known.

Diagnosis. Maladera tempestiva sp. n. resembles in its ex¬

ternal and genital morphology somewhat M. servitrita. The

new species differs from the latter by the shiny head as

well as by the very deep incision of its phallobase between

the parameres.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the Latin adjec¬

tive ‘ tempestivus\ (saisonal/ occurring at right time), with

reference on the seasonal occurrence of the species in the

pre-monsoon in May.

Variation. Length: 10.0-10.9 mm, elytral length: 7.5-7.6

Aedeagus: Fig. 19P-R. Habitus: Fig. 361. Female un¬

known.

Diagnosis. Maladera neotridentipes sp. n. is in its shape

of the aedeagus very similar to M. significabilis Brenske,

but in the new species the parameres are at the apex with¬

out external small teeth, instead, it has a blunt tooth-like

extension on the dorsal median margin of the left para-

mere, which is absent in M. significabilis.

Etymology. The name (noun in apposition) of the new

species is derived from the composed latin words, ‘tri-’

(prefix; three), the nouns "dens' (thooth) and ‘ pes ’ (limp),

plus the Greek prefix ‘neo-’ (new).

Distribution. See map (Fig. 49E).

Aedeagus: Fig. 19W-Z. Habitus: Fig. 36M.

Diagnosis. Maladera antispinosa sp. n. differs from the

two very similar species M. subspinosa (Brenske) and M.

senta (Brenske) by the distal process of the basal lobe of

the right (i.e. left ) paramere being longer and ending with

the apex of the paramere, the right paramere is in this new

species before its base without a large concave excava¬

tion (lateral view) but nearly evenly curved.

Etymology. The new species is named (adjective in the

nominative singular) with reference to its high similarity

to M. subspinosa but the presence of antisymmetric para-

meres with the combined Latin words ‘anti-’ (against) and

‘spinosus’ (with spines).

Variation. Length: 10.6-11.1 mm, length of elytra:

77-8.2 mm, width: 6.6 mm. Female: antennal club slight¬

ly shorter than the remaining antennomeres combined, py¬

gidium weakly convex.

Remarks. The only available specimen appears left-right

symmetry reversed (see Ahrens & Lago 2008) compared

to M. subspinosa. The here mentioned right paramere is

in fact on the left side and vice versa for the left one.

Distribution. See map (Fig. 50B).

Aedeagus: Fig. 20A-C. Habitus: Fig. 36N. Female un¬

known.

Diagnosis. Maladera balphakramensis sp. n. is rather dis¬

similar from all species from the Indian subcontinent, be¬

ing in its external morphology similar to M. taiwana No¬

mura, 1974 from Taiwan. It may be distinguished from the

Taiwanese species by the longer and narrower parameres

and the long basal branch of the right paramere, which in

M. taiwana is completely absent.

Etymology. The new species is named after its occurrence

in the Balphakram Nat. Park (adjective in the nominative

singular).

Distribution. See map (Fig. 50B).

Aedeagus: Fig. 20H-K. Habitus: Fig. 37B. Female un¬

known.

Diagnosis. Maladera allolaterita sp. n. differs from M. la-

terita in the base of the right paramere being medio-dor-

sally not enlarged. From the similar M. nilgirina (Frey)

the new species differs by having the mesal sinuation of

the right paramere more basal and the left paramere lack¬

ing an apical hook.

Etymology. The name (noun in apposition) of the new

species is derived from the combined Greek prefix ‘ alio -

’ and the species name ‘ laterita\ with reference to its sim¬

ilarity to M. laterita.

Distribution. See map (Fig. 50E).

Diagnosis. Maladera bangaloreensis sp. n. differs from,

the in external characters very similar, M. slateri in hav¬

ing the left paramere in dorsal view spherical at base. The

aedeagus of M. bangaloreensis is rather more similar to

M. westermanni (Brenske), from which the new species

differs by having the distal portion of the left paramere

more elongated than the part of the spherical base.

Etymology. The new species is named with reference to

its type locality, Bangalore (adjective in the nominative

singular).

Variation. Length: 7.6-8.2 mm, length of elytra: 5.3-5.4

mm, width: 4.4-4.5 mm.

Remarks. From the original description it is not evident

on how many type specimens the description was based.

Therefore, a lectotype is designated here. From the iden¬

tity of the species results the following genus synonymy:

Maladera (sbg. Cephaloserica ) = Coronoserica Brenske,

1902, syn. n.

Distribution. Since all relatives of M beata live in Asia

and recent records are all from southern India, we feel that

locality labels of the lectotype (type locality: Sierra Leone)

must be erroneous (Fig. 50E).

Distribution. Southern Indian and Sri Lanka (Fig. 50F).

Remarks. Fabrizi & Ahrens 2014 stated already the great

similarity of this species with the species of the subgenus

Maladera (Cephaloserica ). The presence of an antennal

club with more than three antennomeres in another species

(M bombycinoides ) that showed additionally in the gen¬

italia a high similarity with the subgenus Cephaloserica ,

makes it more likely that also in M. bombycina the anten¬

nal club is modified rather to hypothesize multiple con¬

vergence developments for the similar morphology of the

head and the legs. Therefore, this species is grouped in¬

side Maladera (subgenus Cephaloserica ), although its

aedeagus is still quite different from all the other species

of the group.

Diagnosis. Maladera bombycinoides sp. n. differs from

M. bombycina (Karsch) by the longer and reflexed anten¬

nal club that is 1.5 times as long as all remaining anten¬

nomeres combined, while M. bombycinoides differs from

all other species of the subgenus Cephaloserica by the

male antennal club being composed of 4 anntennomeres.

Etymology. The new species is named (noun in apposi¬

tion) with reference to its similarity to M. bombycina , with

the combined species name ‘ bombycina ’ and the Greek

suffix ‘- oides ’ (-like).

of before the apex) abruptly narrowed.

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

cality, Dunhinda (adjective in the nominative singular).

Distribution. See map (Fig. 50F).

Aedeagus: Fig. 20Aa-Ac. Habitus: Fig. 37H.

Diagnosis. The species differs from the similar M. bom-

bycina (Karsch) in the longer, reflexed antennal club, as

well as by the left paramere having a long filiform and

sharply pointed basal lobe.

Etymology. The new species is derived (adjective in the

nominative singular) from the Latin adjective, ‘ facetus ’

(delicate), with reference to its fine filiform basal lobe of

left paramere.

Distribution. Its type locality was not sufficiently exact¬

ly described on the specimens labels, therefore, the exact

distribution of M. faceta sp. n. is unknown.

Aedeagus: Fig. 21D-I. Habitus: Fig. 37J.

Diagnosis. Maladera johannesi sp. n. is very similar to

M. hongkongica (Brenske) from southern China, but dif¬

fers from the latter by the slightly shorter right paramere,

which is on its ventral margin not sinuate as in M.

hongkongica , but straight. The left paramere is short and

strongly curved, basally strongly and spherically widened

and with a short narrow distal process only.

Etymology. The new species is named (noun in genitive

case) in honour of the curator Johannes Frisch (Berlin).

Variation. Length: 11.1-12.0 mm, length of elytra:

8.1-8.5 mm, width: 6.5-6.9 mm. Female: Antennal club

slightly shorter than remaining antennomeres combined,

pygidium weakly convex.

Aedeagus: Fig. 21J-M. Habitus: Fig. 37K. Female un¬

known.

Diagnosis. Maladera kostali sp. n. is in its external ap¬

pearance very similar to M. sunaiensis sp. n. but differs

in the weak and short median keel on the anterior labro¬

clypeus, as well as in the right paramere being straight and

distinctly widened towards the apex. The right paramere

is in Maladera kostali sp. n. straight instead of being

curved interiorly as in M. sunaiensis sp. n.

Etymology. The new species is named (noun in genitive

case) after one of its collectors, Mr. Kostal.

Variation. Length: 6.5-6.9 mm, length of elytra: 4.5-5.0

mm, width: 3.4^1.3 mm. Dorsal surface may be weakly

shiny.

Remarks. Autos erica tyrannica Brenske was described

based on two female specimens which are in their exter¬

nal morphology, particularly in the shape of their metat¬

ibia and labroclypeus highly similar to M. opalescens.

Therefore, both species are viewed as synonymous here.

Both syntypes of A. tyrannica are weakly shiny, obvious¬

ly the dull toment is abraded; their antenna is not com¬

posed of nine antennomeres as mentioned by Brenske

(1898: 227) but of 10.

the shape of parameres: left paramere basally subsphaer-

ical, right paramere at middle abruptly narrowed.

Etymology. The name (adjective in the nominative sin¬

(shortened), with reference to the, compared to M.

hongkongica , shortened left paramere.

Remarks. As already mentioned by Ahrens (2004b), the

species group around Hemiserica nasuta includes also taxa

that have no produced snout-like labroclypeus. Treating

those taxa not as Hemiserica would make them probably

a paraphyletic group, the same would apply for their next

closest relatives of Maladera. Thus we decided here to in¬

clude formally all so far described Hemiserica species as

a subgenus within Maladera.

nomeres. Therefore, the systematic position of this

species is very uncertain, the rostrum-like shape of the

labroclypeus could be easily seen as a convergent devel¬

opment. In order to avoid a preliminary and probably in¬

correct new combination (e.g. Neoserica insertae sedis),

we kept the species name here under its original combi¬

nation inside Maladera (subgenus Hemiserica).

Aedeagus: Fig. 23J-L. Habitus: Fig. 38G.

Diagnosis. Maladera lorenzi sp. n. differs from ah other

Hemiserica species by the dorsal process of the right para-

mere, which is short and truncate apically, being slightly

concavely sinuate at apex resulting in a tiny double tip.

Etymology. The new species is named after one of its col¬

lectors, W. Lorenz (noun in genitive case).

Variation. Length: 5.9-6.5 mm, length of elytra: 4.CM.5

mm, width: 3.1-3.6 mm. Female: Antennal club slightly

shorter than in male.

Remarks. The synonymy of Maladera banvayana ubd M.

pygmaea with M. globosa was established by Ahrens

(2004b) based on the study of the complete type materi¬

al (not cited by Krajcik 2012). The subsequent examina¬

tion of the types of M. mutabilis revealed the identity with

M. globosa, given that the parameres of the male type

specimens were virtually identical in shape.

A fourth potential syntype of M. mutabilis of the Fabri¬

cius collection was not designated as a paralectotype since

it is probably not an Indian species and was possibly sec¬

ondarily mixed with the syntypes. Some works consider

incorrectly Olivier (1789) author of this species (e.g. Kra¬

jcik 2012) or even interpreted M. mutabilis Olivier as a

homonym of M. mutabilis Fabriciues (Gyllenhal 1817,

Burmeister 1855). Since we could not locate any syntypes

of Olivier’s M. mutabilis, it is very likely that Melolon¬

tha mutabilis Olivier, 1789 is a nomen nudum.

Maladera trilobata (Khan & Ghai, 1980) comb. n.

Hemiserica trilobata Khan & Ghai, 1980: 40; Krajcik

2012 : 121 .

Remarks. The status of this species is uncertain. Hemis¬

erica trilobata Khan & Ghai, 1980 was described based

on three female specimens from Bombay. Although we

had not the opportunity to examine the type material of

this species, it must be considered to be a highly aberrant

form (given the strongly asymmetric shape of the clypeus;

see Khan & Ghai 1980, Fig. 1A) of M nasuta , which was

previously recorded from Bombay, however, only with fe¬

male specimens (Ahrens 2004). Since so far no male

Hemiserica specimens were available from this region and

given the comparatively high endemism of this subgenus,

we refrain at this stage to synonymise M. trilobata with

M. nasuta.

Aedeagus: Fig. 23T-W. Habitus: Fig. 38M.

Diagnosis. Maladera paraprabangana sp. n. is in its ex¬

ternal appearance very similar to M. clypeata and M. pra-

bangana (from Laos). M. paraprabangana sp. n. differs

from the latter by the shorter left paramere that is mod¬

erately curved ventrally instead of being straight. From M.

clypeata M. paraprabangana sp. n. differs by its darker

colour and the shape of the left paramere, which is in M.

clypeata hook-like and bent dorsally.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived from the combined

greek prefix ‘ para- (beside/ close) and the species name

“prabangana ”, with reference to it similarity to this tax¬

on.

Variation. Length: 12.1-12.8 mm, elytral length: 8.6-9.4

mm, width: 7.2-7.9 mm. Female: antennal club distinct¬

ly shorter than remaining antennomeres combined; pygid¬

ium weakly convex.

Aedeagus: Fig. 23X-Z. Habitus: Fig. 380. Female un¬

known.

Diagnosis. This new species differs from all other Indi¬

an Maladera species by the shape of its aedeagus. At the

moments it is hard to find closer comparisons of M. genic-

ulata with any of the known Indian species.

Etymology. The name (adjective in the nominative sin¬

gular) of the new species is derived form Latin ‘ genicu -

latus ’ (having a knot), with reference to the short and trans¬

verse antennomeres of the antennal funiculus.

Variation. Length: 8.0-10.2 mm, elytral length: 5.8-6.9

mm, width: 4.9-5.9 mm.

Aedeagus: Fig. 24D-G. Habitus: Fig. 39C.

Remarks. M. rosettae (Frey) differs from M. hauseri by

the slightly sinuate anterior margin of the labroclypeus,

the smaller body size, the dull surface, as well as in the

shape of parameres.

It needs to be investigated with more material whether

the observed differences in genital morphology between

the two species might represent only intraspecific varia¬

tion (assignable to subspecies or just local population lev¬

el); at “Nagpore” we found an intermediate paramere

shape between M. rosettae and M. hauseri.

tae from “Kerala, V.1970 Calicut distr. 3500 ft. Nathan”

Diagnosis. The new species differs from all Indian

Maladera species by the small shiny, yellow body, and it

resembles somewhat species of the genus Setiserica

Aedeagus: Fig. 24R-T. Habitus: Fig. 39H.

Diagnosis. Maladera trochaloides sp. n. is in its external

characters and in the shape of the aedeagus rather simi¬

lar to the three species M. placida , M. dimidiata and M

kallarensis sp. n. The new species differs from these taxa

in the shape of its parameres: the right paramere is strong¬

ly curved outwards and has a large internal lobe, its apex

is finely setose, while the other species all have a glabrous

paramere.

Etymology. The name (noun in apposition) of the new

species is derived from the combined Sericini genus name

‘Trochalus ’ and the Greek suffix ‘- oides 5 [resembling]),

with reference to the round body shape which is similar

to the African Trochalus Castelnau, 1832 species.

Variation. Length: 8.8-9.7 mm, elytral length: 6.0-6.5

mm, width: 5.8-6.6 mm. Colour sometimes reddish brown

with yellowish abdomen. Female: Eyes slightly smaller

than in male and body more stout.

types are quite similar to M. drescheri. It might be that

the problems about its identity can be finally resolved once

the Sericini fauna of the regions east of India are complete¬

ilar to those illustrated by Khan & Ghai (1980), which re¬

semble somewhat that of Microserica pruinosa (Hope).

Since this species remains unknown to us we can just spec¬

ZOOGEOGRAPHY

Six hundred fifty-seven species of Sericini are currently

known from the Indian subcontinent, of which 127 are

newly described in this monograph (19%). The greatest

number of species is reported from the Himalaya (368

species), while 293 species are recorded from the main¬

land of the Indian subcontinent (south of Gangetic plain)

and 81 species from Sri Lanka (see Table 1). The major¬

ity (n=69) of the latter are restricted to Sri Lanka (see al¬

so Fabrizi & Ahrens 2014), with only a few species oc¬

curring also in southern India (e.g., Maladera cariniforns,

M. rufocuprea) or even fewer throughout the entire sub¬

continent (e.g., M. setosa). North of the southern Indian

diversity center, major biotic regions are represented by

the arid areas in northwestern of India and Pakistan, con¬

taining only a very few endemic species, and in the greater

part of the elevated Himalayan foothills. However, very

few species from the true Indian fauna reach the plain of

Ganges or the Himalayan foothills, which may be an arte¬

fact of limited collecting activity. One species {Maladera

sericella) belonging to the Maladera marginella group,

with a probable origin on the Indian subcontinent, expand¬

ed into Indochina and currently has the major portion of

its range in the latter region. Additionally, there are a few

doubtful records from specimens in the Staudinger col¬

lection, which represent records of Himalayan species

from southern India and vice versa (e.g., Maladera hi-

malayica himalayica, Chrysoserica auricoma, Meriseri-

ca oberthuri) (see Ahrens 2004b). These records have been

never confirmed by specimens collected at a later date

(therefore should be considered mislabelled). A few

species of the Indochinese and southern Chinese Sercini

fauna, such as Maladera perniciosa, reach northeastern

regions of the Indian subcontinent, or even the eastern Hi¬

malaya like M rufoplagiata.

Considering the general distribution of the material ex¬

amined, any conclusions concerning geographic patterns

and biogeographic implications based on these have to be

assessed with extreme caution. An overview of specimen

distribution evaluated in this study (Fig. 52A) shows wide

ranges of the subcontinent empty of records, and many

other parts with very few records (Figure 53). Most

records and greatest species diversity (>500 records/ 1°

grid cell) are found in the eastern central and eastern Nepal

Himalaya, as well as in the eastern Himalaya (Sikkim-Dar-

jeeling area). Other supposedly diverse regions, e.g. the

Khasi Hills and the Sri Lankan mountains are less intense¬

ly sampled. The Nilgiri Hills and adjacent areas have been

moderately explored, but that area is still well represent¬

ed when compared to the few collections apparent from

other areas of the grid. Least sampled areas are found in

the Deccan trap, as well as in the more arid northwestern

regions. Given this rather fragmentary level of exploration

of the Indian Sericini fauna, many new records and even

new species should be expected in the future.

Six hundred sixty species were included in the analy¬

sis of the patterns of diversity and distribution. Species or

specimens with imprecise label data (e.g., “India” or “Sri

Lanka”) could not be considered in the analysis. The ma¬

jor distribution patterns identified were congruent with

those presented by Ahrens (2004e) with one exception

caused by the recognition of a Sri Lankan “center” and a

western Ghats “center” of endemism, thus extending the

reference frame.

To explore these observations in more detail, we inves¬

tigated the faunal similarity based on all species records

(including data on the Himalaya and Sri Lanka (Fabrizi

& Ahrens 2014)): the WWF ecoregions were clustered

with the Jaccard index (Jaccard 1902) based on presence/

absence data (excluding regions with less than 3 taxa

recorded, which were mainly regions were some taxa oc¬

cur far outside of India). From the analysis of similarity

of faunal composition we discovered 4 principal clusters:

1) the Himalaya, excluding far eastern parts, 2) the north¬

eastern Himalayas, including Meghalaya, Mizoram, the

Brahmaputra valley etc. (see Fig. 52D), 3) the Indian main

continent and 4) Sri Lanka. Cluster 2 associated with the

ecoregions of Indochina and Southern China in the extend¬

ed analysis, which, unfortunately, have not been complete¬

ly sampled and databased. These main clusters were con¬

sistent with known principal biogeographical units (Mani

1974b).

Areas with the highest species richness (Fig. 53) main¬

ly corresponded to the most densely sampled areas, such

as the east-central and eastern Nepal Himalaya, as well

as eastern Himalaya (Sikkim-Darjeeling area), southern

Sri Lanka, Khasi Hills, and central Nepal Himalaya. Apart

from the sampling bias mentioned above, diversity esti¬

mates (Shannon-Weaver index; Chao estimator) confirmed

the patterns of species richness. These zones were broad¬

ly congruent with the hotspot areas identified by Myers

et al (2000).

Within these areas of concentrated diversity, we iden¬

tified several genera or species groups that were highly

restricted to these diversity centers: For the Himalayan

hotspot these were Nepaloserica, Serica (s.str.), Calloser-

ica, Lasioserica, Gynaecoserica, Pachyserica, Amiserica,

Omaladera , Chrysoserica, Xenoserica] for the Western

Ghats, these were Microsericaria , Anomioserica , Meris-

erica , Deroserica. For the Sri Lankan cluster, most char¬

acteristic were Periserica and Selaserica , with many en¬

demic species, as well as the Maladera fistulosa group (the

latter two being distributed in southern India as well; Fab¬

rizi & Ahrens 2014). A few groups extended more wide¬

ly over these regions and some were distributed nearly

over the entire subcontinent, such as the Maladera mar-

ginella group, Maladera (subg. Hemiserica ), the Maladera

indica group, the Maladera lugubris group. The widest

generic distribution we observed was for Maladera (subg.

Cephaloserica ), which occurs on the entire subcontinent,

as well as most of the Oriental region, and two species

have been introduced by man into the Nearctic and the

eastern Mediterranean.

Of specific interest is the disjunct occurrence of the

Neoserica abnormis group, which occurs in Indochina and

Southern China westwards to the Khasi Hills but it is ab¬

sent in the Himalaya. Liu et al. (2015) have shown that

the group is closely related to Nepaloserica (Indian taxa

were, however, were not included in the 2015 analysis).

Therefore, the current disjunct pattern might not represent

the complete scenario due to our incomplete phylogenet¬

ic knowledge and the consequently error-prone classifi¬

cation.

A similar “disjunction” is apparent among the genus Mi¬

crosericaria , in particular for the species M. quadripimc-

tata , which occurs in southern India and also in the Cho-

ta-Nagpur area at the northeastern part of the Deccan trap.

The territory between these two populations has been

poorly investigated for Sericini chafers, thus it is quite dif¬

ficult to speculate on the causes of such a pattern. For fur¬

ther discussion of other more isolated species, especially

those with no apparent relationship to other species (e.g.,

Neoserica and Maladera , species incertae sedis), we need

to understand their phylogenetic relationships or relation¬

ships with neighboring faunas (e.g. China, Indochina).

These may represent isolated relicts or may be part of a

species flock currently invading India (especially in north¬

eastern regions).

For the inference of the biogeographical patterns of the

fauna, the knowledge of the phylogenetic relationships of

the species is essential. Ahrens (2005b, 2006b, c, d, e,

Bonn zoological Bulletin 65 (1 & 2): 1-355

2007a, b, 2012) has made some attempts with the Hi¬

malayan fauna; however, considering all >600 species oc¬

curring on the subcontinent in a single morphology-based

phylogenetic tree inference is quite impossible. Research

using molecular data from this fauna is the only viable so¬

lution that will allow us to answer more detailed questions

about species biogeography, including reconstruction of

historical events. On a global scale, this information is cru¬

cial to help explain the role the Indian subcontinent played

during the invasion of Sericini into Asia from Africa (Eber-

le et al. 2016).

Using accumulated distribution data for the Sericini

species, we investigated ecological similarity between the

single taxa. This was examined through a clustering of

presence/ absence of the species from single ecoregions

(see Fig. 52B). From these graphical clusters, we were able

to infer chafer “assemblages” (Figs 54, 55) for which very

few ecological studies exist. These results represent a new

pathway, attainable directly from museum collections, to

investigate ecological properties of species and assem¬

blages through niche inference and modelling. This infor¬

mation may prove very useful for conservation manage¬

ment as well as for integrated pest management.

CROP PEST SPECIES

In North America, numerous species have become prob¬

lematic crop and turf grass pests after their introduction

into cultural biocenoses from other regions {Maladera cas-

tanea) (Hallock 1932). In India (and possibly also in oth¬

er regions) especially, endemic and indigenous species are

important pests, probably caused by changes of relevant

structure in the ecosystem through environmental impact

of intensive agriculture. Numerous reports are available

chronicling such problems (e.g. Sarma 1982, Patel et al.

1982). Given the lack of proper taxonomic revisions and

easy-to-handle identification keys, surveys are often un¬

reliable (Nair 1986) and the identity of pests often can¬

not be clarified by local pest managers (e.g., Pal & Mis-

ra 1973, Argaman 1986, GoTberg et al. 1986, Klein &

Chen 1983). The present monograph represents a first

primer to improve this situation by providing access to a

proper taxonomic treatment of the group, which will hope¬

fully stimulate future taxonomic, faunistic and ecological

research on these chafers in India.
