Materials to the rove beetles fauna (Coleoptera: Staphylinidae) of the Commander Islands (Kamchatka Region, Russia)

Abstract

A faunistic review of rove beetles of the Commander Islands (Russia, Pacific Ocean) is given. The material was collected on Bering Island (2012, 2013 and 2015) and Toporkov Island (2015). During the investigation 18 species of Staphylinidae belonging to 12 genera from 4 subfamilies were collected. Two species of Staphylinidae are recorded for the first time for Palaearctic (Atheta malleoides Lohse, 1990 and Boreostiba campbelliana (Lohse, 1990)) and nine species for the Commander Island (Arpedium brachypterum (Gravenhorst, 1802), Olophrum boreale (Paykull, 1792), Omalium strigicolle Wankowicz, 1869, Atheta malleoides Lohse, 1990, Boreophilia fusca (C.R. Sahlberg, 1831), Boreostiba campbelliana (Lohse, 1990), Psammostiba hilleri (Weise, 1877), P. kamtschatica (Brundin, 1943), and Stenus juno Paykull, 1789). The rove beetle fauna of the archipelago is presently represented by 30 species, 12 of which have Holarctic ranges (Adota maritima (Mannerheim, 1843), Atheta malleoides and Boreostiba campbelliana occur only on the northern Pacific Ocean coasts), five are distributed in the Eastern Palaearctic and one is trans-Palaearctic species.
