Review of species of the genus Cercyon of Russia and adjacent regions. VI. Subgenus Cercyon, the C. shinanensis group (Coleoptera: Hydrophilidae)

S.K. Ryndevich, H. Hoshina & A.A. Prokin

Abstract. The Cercyon shinanensis species group with two included species is erected within the nominotypical subgenus of Cercyon Leach, 1817. This group is compared with other Palaearctic species groups of Cercyon s. str. The little-known C. shinanensis Nakane, 1965 from Japan (Honshu) is redescribed and its diagnostic features are given. Cercyon sundukovi sp. nov. is described from the Russian Far East (Kunashir Island).
