Key words: Coleoptera; Histeridae; middle Kuril Islands; Russia.
A team of American, Russian and Japanese biologists surveyed the flora and fauna of the middle Kuril Islands, Russia in August, 1995. As a team member, I collected coleopterans from Urup, Broutona, Chirpoi, Simushir, Ushishir, Ketoi, and Rasshua islands. Hypocaccus lewisii, from Urup, was the only histerid collected in this expedition. This species was previously known from Kyûshû, Honshû, Hokkaidô, southern Primorsky and southern Sakhalin. This is a new record for the Kuril Islands.
