Abstract

Seven species of the subgenus Tersilochus, genus Tersilochus, are described from the Russian Far East and Japan in this paper: T. grandiculus sp. nov., T. hokkaidoensis sp. nov., T. impunctator sp. nov., T. juxtus sp. nov., T. konishii sp. nov., T. offrenatus sp. nov. and T. spasskensis sp. nov. Two species, T. curvator Horstmann and T. liopleuris (Thomson), are recorded from the Russian Far East for the first time. A preliminary key to nine species of the subgenus Tersilochus, occurring in the Russian Far East and Japan, is given.
