Short description
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 11; Raggi anali molli: 8. Can be distinguished by the following diagnostic characters: extremely long upper lobe of caudal fin relative to lower lobe; adipose keel developed as high and long ridge, extending anteriorly almost to posterior margin of dorsal-fin base; very closely aligned lateral bars on body, numbering more than 22 (22-26); body scaled; vertebrae 4+41- 42 (Ref. 93044).
Inhabits streams of mountain valleys in areas with swift current over rocky and stony substrates, interspersed with sand and gravel in higher elevation reaches (1781 m asl) and in areas with slower current in the lower reaches (1274 m asl) (Ref. 93044).
