''Tylognathus'' is an invalid genus of ray-finned fishes in the family Cyprinidae. It was established by Heckel in 1843 without a type species. ''Varicorhinus diplostomus'', described by Heckel in 1838 and erroneously redescribed by the same author in 1844 as ''T. valenciennesii'', was later designated the type species. Today this fish is placed in the genus ''Bangana''. The members of this polyphyletic assemblage mainly belong to the group which is known as the subfamily Labeoninae to some authors and the tribe Labeonini of subfamily Cyprininae by others. The 34 taxa formerly placed in ''Tylognathus'' are:〔Froese, R. and D. Pauly. (Eds.)
