検索表 | 形態学 | 形態計測学
背鰭 (合計) : 10; 臀鰭: 8; 脊つい: 42 - 43. Together with Barbatula altayensis and B. sawadai, this species differs from all other congeners from northern Asia by having the body scaled predorsally (vs. body scaled posterior to the dorsal-fin origin, or scales only on the caudal-fin base). It can be distinguished from B. altayensis and B. sawadai in having widely separated nostril (vs. closely-set) and further from B. altayensis in having 42-43 vertebrae (vs. 44-45), and further from B. sawadai in having 7 branched dorsal-fin rays (vs. 8) (Ref. 93050).
Facultative or obligate air-breathing (Ref. 126274)
