Revision of the genus Ptomaphagus Hellwig (Coleoptera Leiodidae Cholevinae) from the Russian Far East and the Korean Peninsula

摘要

The conundrum of Ptomaphagus (s. str.) sibiricus Jeannel, 1934 (Coleoptera, Leiodidae, Cholevinae, Ptomaphagini) is solved, and it is redescribed and newly recorded in South Korea. A new species is also described from the Russian Far East: Ptomaphagus (s. str.) hayashii >sp. n. Relevant morphological characters of the concerned species are illustrated with colour plates, and their known distributions are mapped.
