Abstract

The current paper presents new locality records, including first state records for Mizoram, of 92 species of Sericini (Coleoptera: Scarabaeidae: Melolonthinae) from the Indian subcontinent. Eight new species are described herein: Maladera alloservitrita sp. n., M. kolasibensis sp. n., M. mizoramensis sp. n., Neoserica radhanagariensis sp. n., Serica (s. str.) basantapurensis sp. n., S. (s. str.) mahakaliensis sp. n., S. (s. str.) therathumensis sp. n., and S. (s. str.) zianii sp. n.

Introduction

The taxonomy of the rich fauna of the sericine chafer beetles (Scarabaeidae: Melolonthinae: Sericini) of the Indian subcontinent was revised in detail recently by a series of papers and monographs (see Ahrens 2004, Fabrizi and Ahrens 2014, Ahrens and Fabrizi 2016). In the framework of a collaboration project between German and Indian chafer taxonomists funded by the German Science foundation (DFG), recently, we were able to study further new material from this region, particularly the material preserved in Indian research institutions, and the first results of the examination of these specimens are presented in this paper. Eight new species are discovered and described herein, and new data on the distribution of 84 additional species and one subspecies are given.

Materials and methods

The principal terminologies and methods used for specimen dissection and genital preparation are described in detail in Ahrens (2004). For identification of the species, genitalia of all male specimens were examined. After examination, male genitalia were glued on a small pointed card. All 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. Genitalia of the new species were photographed in both lateral and dorsal views using a stereomicroscope Leica M125 with a Leica DFC420C digital camera. The stacking of the separate images was done using Leica Application Suite (V3.3.0) where a number of separate partly focused images were combined in order to obtain an image that was in focus throughout. The resulting images were subsequently digitally edited to remove errors of the Automontage reconstruction and to obtain a white background. New records were commented in case of a new record for a state or country.

Aedeagus: Fig. 1A–D. Habitus: Fig. 1E. Female unknown.

Diagnosis

Maladera alloservitrita sp. n. resembles M. servitrita (Brenske, 1898) in its external and genital morphology. The new species differs from the latter by angles of the dorsomedian process of phallobase and the shape of the parameres: the left paramere is not fused with the phallobase, the right one is short not being extended beyond the apex of the left paramere.

Etymology

The name (adjective in the nominative singular) of the new species is derived from the combined Greek prefix allo (other-) and the name servitrita, with reference on the high similarity to the closely related species M. servitrita.

Diagnosis

Diagnosis

Maladera mizoramensis sp. n. is in the shape of the genitalia and in its external morphology similar to M. unguicularis (Brenske, 1898). The new species differs from M. unguicularis by the more elongate phallobase.

Etymology

The name (adjective in the nominative singular) of the new species is derived from its occurrence in Mizoram state of India.

Diagnosis

Serica basantapurensis sp. n. is in external and genital morphology very similar to S. bhaktai Ahrens, 1999 and S. narya Ahrens, 1999 from central Nepal and Darjeeling, respectively. The new taxon differs from the two by the apically wide right paramere (distinctly wider than in S. bhaktai), whose median apex is not as deeply sinuated as in S. narya Ahrens, 1999.

Etymology

The name (adjective in the nominative singular) refers to the type locality close to Basantapur (Nepal).

Diagnosis

Serica mahakaliensis sp. n. is in external and genital morphology very similar to S. kumaonensis Ahrens, 1999. The new taxon differs by the shorter and wider left paramere, and the lateral elongate branch of the right paramere that inserts at the middle of the paramere in Serica mahakaliensis sp. n. (at apical third in S. kumaonensis).

Etymology

The name (adjective in the nominative singular) refers to the Mahakali zone (Nepal).

Variation

Length: 8.0-9.5 mm, length of elytra: 5.4-6.5 mm, width: 4.5-5.0 mm. Female: Antennal club slightly shorter than remaining antennomeres combined, eyes small, ratio diameter/ interocular width: 0.5.

Aedeagus: Fig. 4A–C. Habitus: Fig. 4D. Female unknown.

Diagnosis

Serica therathumensis sp. n. is very similar to S. tropdeana Ahrens, 1999 and S. thibetana Brenske, 1897 in external and genital morphology. The new taxon differs from the two by the basal tooth of the inner protarsal claw being straight (not lobiform as in S. tropdeana and S. thibetana) and truncate at apex as well as the shape of parameres: the left paramere is laterally not widened while the right one is slightly shorter than in S. thibetana but distinctly narrower at apical half than in S. tropdeana.

Etymology

The name (adjective in the nominative singular) refers to the Therathum district (Nepal).

Variation

Length: 6.5-8.0 mm, length of elytra: 4.9-5.5 mm, width: 3.7-3.8 mm.

Aedeagus: Fig. 4E–G. Habitus: Fig. 4H. Female unknown.

Diagnosis

Serica zianii sp. n. is rather similar to S. olivacea Brenske, 1896 in external appearance and genital morphology. The new taxon differs by the strongly concave lateral margin of pronotum (in which it is similar to Serica arborea Ahrens, 1999 and S. sticta Ahrens & Fabrizi, 2009), the larger size, as well as the slightly longer antennal club of male. Genitalia are well distinct from those of S. olivacea Brenske, 1896: in S. zianii sp. n. the right paramere is only half the length of the left paramere.

Etymology

The name (adjective in the nominative singular) is named after its collector, Stefano Ziani (Forli, Italy).
