Abstract

The species belonging to the genus Ptomaphagus Hellwig, 1795 (Coleoptera, Leiodidae, Cholevinae, Ptomaphagini) from eastern Asia are assigned to three species groups. Group yasutoshii has a single species: P. (s. str.) yasutoshii Nishikawa, 1993 from Taiwan, China. Group nepalensis with three species: P. (s. str.) nepalensis Perreau, 1988 from Nepal and P. (s. str.) masumotoi Nishikawa, 2011 from Thailand are redescribed, and P. (s. str.) piccoloi Wang, Růžička, Nishikawa, Perreau & Hayashi, 2016 is recorded for the first time from China (Zhejiang). Group sibiricus with seven species, including two newly described Chinese ones P. (s. str.) funiu sp. n. from Henan, and P. (s. str.) haba sp. n. from Yunnan, and five known species: P. (s. str.) chenggongi Wang, Nishikawa, Perreau, Růžička & Hayashi, 2016, P. (s. str.) hayashii Wang, Růžička, Perreau, Nishikawa & Park, 2016, P. (s. str.) kuntzeni Sokolowski, 1957 (distribution records from Myanmar excluded), P. (s. str.) sibiricus Jeannel, 1934 and P. (s. str.) tingtingtae Wang, Nishikawa, Perreau, Růžička & Hayashi, 2016. Specimens of other undescribed species of the group sibiricus are also recorded, revealing a high diversity of this genus in eastern Asia, especially in central and north Sichuan, China, which essentially remains to be investigated. Relevant morphological characters of the examined species are illustrated with colour plates, and their known distributions are mapped. A key to species of Ptomaphagus from eastern Asia is provided.
