New species of Nipponoserica and Paraserica from China (Coleoptera, Scarabaeidae, Sericini).

The species of the genera Nipponoserica Nomura, 1973 and Paraserica Reitter, 1896 from China are revised. The following eight new species are described from China: Paraserica camillerii Ahrens, Fabrizi, & Liu, sp. n., P. mupuensis Ahrens, Fabrizi, & Liu, sp. n., P. wangi Ahrens, Fabrizi, & Liu, sp. n., Nipponoserica alloshanghaiensis Ahrens, Fabrizi, & Liu, sp. n., N. anjiensis Ahrens, Fabrizi, & Liu, sp. n., N. jiankouensis Ahrens, Fabrizi, & Liu, sp. n., N. henanensis Ahrens, Fabrizi, & Liu, sp. n., and N. sericanioides Ahrens, Fabrizi, & Liu, sp. n. A key to the species of the genera examined here and maps of the species distribution are provided. Habitus and male genitalia are illustrated.

Introduction

In the course of the revision of the of China a series of papers was published recently dealing mainly with the genera that possess a multi-lamellate antennal club (Ahrens et al. 2014a, b, c; Liu et al. 2014a, b, c, 2015; Liu et al. 2016). In continuation with this work, the results of the revision of the genera Reitter, 1896 and Nomura, 1973, both representing genera with a tri-lamellate antennal club, are presented here. So far, both groups are poorly known in China. While is known only from four species, is known from a single species from mainland China (Ahrens 2004b; Ahrens and Bezdek 2016). The examined material from different private and institutional collections contained a number of new species which are described herein. Furthermore, the material included numerous new and interesting locality records that are also given.

Materials and methods

The terminology and methods used for measurements, specimen dissections, and genital preparation follow Ahrens (2004a). Data from specimens examined are cited in the text with original label contents given in quotation marks, multiple labels are separated by a “/”. Male genitalia were glued to a small pointed card attached to the specimen. Descriptions and illustrations of new taxa are based on the holotype or lectotype specimen, while the variation of other specimens is given separately. All descriptions and measurements were made under an Olympus SZX 12 microscope, and all genital and habitus illustrations were made with a digital camera (AxioCam HRc) attached to a stereo microscope (Zeiss Stereo Discovery V20) and Axio Version 4.8 software. The distribution maps were generated using Q-GIS 2.0.1 and Inscape software. Type specimens and other examined material are deposited in the following institutions or collections:

Museum of Hebei University, Baoding (Hebei Prov.), China;

Institute of Zoology, Chinese Academy of Sciences, Beijing, China;

The species occurs in the central mountainous part (Nantou County) of Taiwan.

Species is known (from Taiwan) only from female, thus the true identity of this species is uncertain yet. We had no chance yet to examine the holotype. Given its occurrence (Nantou County) in the central mountainous part of Taiwan which is characterised by a high endemism, it is highly improbable that this species does also occur in mainland China.
