Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các vây lưng mềm (tổng cộng) : 12; Tia mềm vây hậu môn: 8. Schistura epixenos can be diagnosed from its congeners in the Xe Bangfai and
adjacent drainages in central and southern Laos by the following combination of characters: pale brown body with 13-17 dark brown bars, about as wide as interspaces, reaching downwards to the level of pectoral-fin base; processus dentiformis narrow, pointed; lateral line complete; caudal peduncle depth 1.3-1.5 times in its length; body slender (13.7-15.1 % SL); scales present in predorsal area; pelvic fin not reaching anus; and origin of pelvic fin below origin of dorsal fin (Ref. 117206).
Occurs in stream characterized by forest cover, very narrow, dense cover of branches, bamboos and shrubs. The stream is shallow with depth of 1-30 cm and bottom covered by thick mud (probably due to the track construction and recent agricultural work), at places with thick
layers of leaf litter (Ref. 117206).
