A taxonomic review of intertidal Bryothinusa Casey (Coleoptera: Staphylinidae: Aleocharinae) in Korea

Abstract

A taxonomic review of Korean intertidal species of Bryothinusa Casey is presented. Eight species are recognized, five of which are new additions to the Korean fauna (Bryothinusa algarum Sawada, B. hokkaidensis Liu, Ono and Maruyama, B. itsuroi Liu, Ono and Maruyama, B. japonica Liu, Ono and Maruyama, and B. nigra Liu, Ono and Maruyama). Previous record of B. nakanei Sawada was an incorrect identification of B. nigra. A key, diagnoses, habitus photographs, and line drawings of median lobe and spermatheca are provided to facilitate identification.
