Type specimens of nominal species Nemacheilus compressirostris Warpachowsky, 1897, and N. sibiricus Gratzianov, 1907, from the upper Ob River basin were redescribed, and lectotypes for both species were selected. Although some traits were not preserved well enough, it was established that both names should be classified with Barbatula cf. toni, corresponding to the “snub-nosed” morphotype fide Prokofiev (2007). None of the names are suitable for designation of the morph “tigris” fide Gundrizer (1975) and Prokofiev (2007). A comparison table of diagnostic traits of the genus Barbatula from the Asian part of the range was compiled.
