Further studies on the Pselaphodes complex of genera from China (Coleoptera, Staphylinidae, Pselaphinae)

Abstract

New data on the Pselaphodes complex of genera (Pselaphitae: Tyrini) from China is presented. The generic limits of Labomimus Sharp and Pselaphodes Westwood are discussed and expanded. A revised key to the genera of the Pselaphodes complex is provided. New geographic evidence suggests that previously believed wide-spread species Pselaphodes tianmuensis Yin, Li & Zhao contains a number of related species, resulting in a division of the species to nine separate taxa. Fourteen new species belonging to three genera are diagnosed, described and illustrated: Dayao emeiensis Yin & Li, sp. n. (Sichuan), Labomimus fimbriatus Yin & Hlaváč, sp. n. (Yunnan), L. jizuensis Yin & Hlaváč, sp. n. (Yunnan), L. simplicipalpus Yin & Hlaváč, sp. n. (Sichuan), Pselaphodes anhuianus Yin & Li, sp. n. (Anhui), P. daii Yin & Hlaváč, sp. n. (Sichuan), P. grebennikovi Yin & Hlaváč, sp. n. (Yunnan), P. hainanensis Yin & Li, sp. n. (Hainan), P. kuankuoshuiensis Yin & Li, sp. n. (Guizhou), P. longilobus Yin & Hlaváč, sp. n. (Hunbei, Yunnan), P. monoceros Yin & Hlaváč, sp. n. (Xizang), P. pengi Yin & Li, sp. n. (Sichuan), P. tiantongensis Yin & Li, sp. n. (Zhejiang) and P. wrasei Yin & Li, sp. n. (Yunnan). Labomimus sichuanicus Hlaváč, Nomura & Zhou (Sichuan) is redescribed and illustrated based on a paratype and the material from the type locality. Two recently described species, Pselaphodes tibialis Yin & Li (Yunnan), and P. venustus Yin & Li (Yunnan), are transferred to Labomimus (comb. n.) due to the presence of a median metaventral fovea. New locality data is provided for P. aculeus Yin, Li & Zhao (Anhui, Fujian, Guangxi, Hainan, Yunnan), P. maoershanus Yin & Li (Guangxi, Guizhou), P. tianmuensis (Zhejiang, Anhui, Fujian, Jiangxi, Guangxi) and P. pectinatus Yin, Li & Zhao (Hainan), with the aedeagus newly illustrated for the latter species.
