title: Bembidion (?Nipponobembidion) ruruy sp. n., a new brachypterous ground beetle (Coleoptera, Carabidae) from Kunashir Island, Kuriles, Russia.
abstract: A new species, Bembidion (?Nipponobembidion) ruruysp. n., is described from the foot of Ruruy Volcano, Kunashir Island, Kuril Archipelago, Russia. It is only the second consubgener, being characterized by the reduced wings, the rounded elytral shoulders, and the backward position of the posterior supra-orbital pore. In this connection, the subgenus Nipponobembidion Habu & Baba, 1968 is rediagnosed and both of its species are keyed. It might have originated from Plataphodes Ganglbauer, 1891, possibly in relation to volcanic activities in the region.
