The 6.5 to 8.5 large rove beetle Deleaster dichrous (family Staphylinidae) is the only representative of the genus Deleaster in Germany. Contrary to many other rove beetles, the stenotopic, ripicolous species is easily recognized by the habitus and its conspicuous coloration with black head and abdomen, red pronotum and orange elytra. It is widespread in the western Palearctic and has been introduced to the northeast coast of North America. Deleaster dichrous lives on sandy riverbanks and lakeshores, mainly on the wet sand, under stones and rubble, in detritus and occasionally on the lower vegetation. The nocturnal animals swarm during dusk and are regularly attracted to light. In Germany, recent records are known from virtually all Federal States and Deleaster dichrous is regarded as not endangered. (CB)
