Issue
Questionably a synonym of Barbatula toni (Dybowski, 1869) in Eschmeyer (CofF ver. Nov. 2011: Ref. 88798).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Temperate

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 22.0 cm TL male/unsexed; (Ref. 51717)
Dorsal soft rays (total): 10; Anal soft rays: 8; Vertebrae: 40 - 42. Distinguished from all other species of Barbatula from northern Asia by having an upper lip with a marked and deep median indention (vs. slight and shallow) and a nearly scaleless body or scales only on the caudal-fin base (vs. body scaled posterior to the dorsal-fin origin or a fully scaled body). Can be further diagnosed from B. dgebuadzei in having closely-set nostrils (vs. widely separated) and 40-42 vertebrae (vs. 43-45). Similar to both Barbatula altayensis and B. sawadai in the shared presence of closely-set nostrils, a character distinguishing them from all other congeners from northern Asia with widely separated nostrils. Can be further diagnosed from B. altayensis in having 40-42 vertebrae (vs. 44-45), and from B. sawadai in having 7 branched dorsal-fin rays (vs. 8). Resembles B. compressirostrisi (or B. golubtsovii) and B. dgebuadzei in scalation in that the body is scaleless or scales only on the caudal-fin base. Further differs from B. compressirostrisi (or B. golubtsovii) in having 40-42 vertebrae (vs. 45-47) and closely-set nostril (vs. widely separated) (Ref. 93050).
Facultative or obligate air-breathing (Ref. 126274)
