Abstract
Sculpin from the Kolyma, Dukcha, and Glukhaya rivers is described as a new species Cottus kolymensis from the species group “Cottus poecilopus”. This species differs from the remaining species of the group (C. altaicus, C. szanaga, C. kuznetzovi, C. koreanus, and C. volki) in the combination of several characteristics: very short internal ray of ventral fin averaging 1/5 of the long ray; comparatively wide interorbital space equal or slightly smaller than longitudinal eye diameter, presence of teeth on palatine bones; as a rule, paired fifth pore of the preoperculo-mandibular canal; and an incomplete lateral canal terminating in two to three autonomous segments and opening by (13 + 2 + 2)-(23 + 2 + 2 + 2) pores.
