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), Labomimus jizuensis Yin & Hlaváč, sp. n. (Yunnan), Labomimus simplicipalpus Yin & Hlaváč, sp. n. (Sichuan), Pselaphodes anhuianus Yin & Li, sp. n. (Anhui), Pselaphodes daii Yin & Hlaváč, sp. n. (Sichuan), Pselaphodes grebennikovi Yin & Hlaváč, sp. n. (Yunnan), Pselaphodes hainanensis Yin & Li, sp. n. (Hainan), Pselaphodes kuankuoshuiensis Yin & Li, sp. n. (Guizhou), Pselaphodes longilobus Yin & Hlaváč, sp. n. (Hunbei, Yunnan), Pselaphodes monoceros Yin & Hlaváč, sp. n. (Xizang), Pselaphodes pengi Yin & Li, sp. n. (Sichuan), Pselaphodes tiantongensis Yin & Li, sp. n. (Zhejiang) and Pselaphodes 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 Pselaphodes 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 Pselaphodes aculeus Yin, Li & Zhao (Anhui, Fujian, Guangxi, Hainan, Yunnan), Pselaphodes maoershanus Yin & Li (Guangxi, Guizhou), Pselaphodes tianmuensis (Zhejiang, Anhui, Fujian, Jiangxi, Guangxi) and Pselaphodes pectinatus Yin, Li & Zhao (Hainan), with the aedeagus newly illustrated for the latter species.

Notes on the Pselaphodes Westwood complex (Coleoptera, Staphylinidae, Pselaphinae) of Hubei, China, with description of a new species and additional faunistic data

“…The Pselaphodes Westwood complex of genera (sensu Hlaváč 2003 ) is a speciose group including nine morphologically similar, and probably also phylogenetically close, genera ( Yin et al 2013a ) of the tribe Tyrini that are diversified primarily in the Oriental Region. As of 1 st May, 2024, 179 species of this complex have been described ( Newton 2022 ).…”

“…As of 1 st May, 2024, 179 species of this complex have been described ( Newton 2022 ). The most diverse genus, Pselaphodes Westwood, contains 87 species (e.g., Huang et al 2018a , 2018b ; Huang and Yin 2019 , 2020; Yin 2019 ; Yin and Li 2021 ), followed by Labomimus Sharp with 48 species (e.g., Zhang and Yin 2019 ; Zhang et al 2019 ; Li and Yin 2020 ; Yin and Li 2021 ), Linan Hlaváč with 17 species (e.g., Yin et al 2011a ; Yin and Li 2013a ; Zhang et al 2018 ; Zhao et al 2019 ), Lasinus Sharp with 12 species ( Bekchiev et al 2013 ; Yin et al 2014 ), and the other, smaller genera Nomuraius Hlaváč ( Huang and Yin 2018 ), Paralasinus Hlaváč & Nomura ( Hlaváč and Nomura 2001 ), Taiwanophodes Hlaváč ( Bekchiev 2010 ), Dayao Yin, Li & Zhao ( Yin et al 2011b , 2013a ), and Indophodes Hlaváč ( Hlaváč 2003 ), each comprising no more than five species.…”

A new species of Linan Hlaváč (Coleoptera, Staphylinidae, Pselaphinae) from Shenzhen, China

“…The Oriental genus Linan Hlaváč, 2003 belonging to the ‘ Pselaphodes complex’ of genera (Hlaváč 2003; Yin et al 2013a) is a small group containing 16 species distributed in China (16 spp.) and Thailand (1 sp.)…”
