- Аннотация: Russian Far East loaches of the genera Cobitis and Misgurnus are among members of the family Cobitidae with poorly understood systematics. In this study we present phylogenetic hypotheses based on mitochondrial (cytochrome b) and nuclear (RAG-1) sequences. All analyses recovered comparable topological phylogenies, and all datasets supported the non-monophyly of the genera Cobitis and Misgurnus. Both genera are represented by multiple lineages that in some cases do not correspond to species described. We found some phylogenetic incongruities for the genus Misgurnus (M. mohoity and M. anguillicaudatus) that are explained by ancient hybridization, as was suggested previously for M. anguillicaudatus. The revealed phylogenetic relationships suggest that Paramisgurnus should be treated as a synonym of Misgurnus, and M. bipartitus as a synonym of M. mohoity. All analyses recovered C. choii as a member of the genus Cobitis confirming previous taxonomic conclusions. Most of the molecular lineages found follow currently recognized taxa with some exceptions as M. anguillicaudatus, and C. lutheri. Phylogenetic relationships recover several unrelated lineages of M. anguillicaudatus and suggest additional studies to solve current taxonomic uncertainty. We found that C. lutheri is a non-natural group that contains two unrelated lineages: specimens of C. lutheri from the Far East of Russia collected close to the type locality, and a second lineage with specimens of C. lutheri from Korea which identification must be revised. The study provides evidence of the presence of Far East species M. nikolskyi in the Sakhalin Island, but simultaneously shows conspicuous genetic distinctiveness between the island and the mainland populations
