First Record of the Polypore Fungus Beetle Genus Eustrophus (Coleoptera: Tetaratomidae: Eustrophinae) in Korea

The family Tetratomidae Billberg occurs in most parts of the world but many species are discovered from Australia and New Zealand. The family contains 13 genera and over 150 described species in five subfamilies, Eustrophinae, Hallomeninae, Penthinae, Piseninae and Tetratominae. Among the eustrophine genera, a genus Eustrophus Illiger includes four species in the Holartic region including three Palaearctic species, E. dermestoides (Fabricius), E. niponicus Lewis and E. yunnanensis Nikitsky. In this study, the genus Eustrophus and its a single species, E. niponicus, are newly discovered from the Korean fauna. A diagnosis, habitus photographs and illustrations of diagnostic characters including aedeagus of the species are provided.
