Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 12; Rayons mous anaux: 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).
Body shape (shape guide): elongated.
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).
