簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 8-10; 臀鰭軟條: 6; 脊椎骨: 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).
