Summary:For the first time, a karyological and molecular genetic ( COI , cytochrome b , 16S rRNA genes) study of the freshwater fish species Cottus kolymensis , recently described from the Dukcha and Kolyma rivers in northeast Asia, was carried out. A complex of karyological and molecular-genetic marker traits has been determined to identify the species. Genetic differences between the populations of C. kolymensis inhabiting the water bodies of the Kolyma River basins and the northern part of the Sea of Okhotsk were found. On their basis, the species is divided into groups in accordance with the habitat. The existence of a separate group Cottus poecilopus within the genus Cottus , which includes taxa of the species rank, including C. kolymensis , has been confirmed.
