Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các vây lưng mềm (tổng cộng) : 8 - 10; Tia mềm vây hậu môn: 6; Động vật có xương sống: 34 - 35. This species is distinguished from all its congeners by the remarkable reduction in the laterosensory system lacking the pores s1, s2, s3 and s6 in the supraorbital line and pore i10 in the infraorbital line (vs. presence of, at least, pore i10) and the lower number of pterygiophores of dorsal fin 8 (vs. 9-14) (Ref. 122319).
Occurs in rivers and streams but has not been collected with its congeners. Stomachs of two specimens contained immature aquatic Diptera (Chironomidae and Simuliidae) and Ephemeroptera (Ref. 122319).
