Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); sexnubes: The specific name sexnubes is Latin meaning ‘six clouds’, in reference to the color pattern of six saddle blotches, like clouds hanging down the sky. A noun in apposition..

Short description
Morphology | Morphometrics
Dorsal
soft rays
(total): 12;
Anal
soft rays: 8. This species can be easily distinguished by the following combination of characters: caudal fin with 8+8 branched rays; incomplete lateral line; a dissociated caudal bar, a shallow caudal-peduncle depth (7.6%?9.6% SL; respectively caudal-peduncle 1.76?1.95 times longer than deep); and no sexual dimorphism. A dorsocephalic pattern consisting of a black, forward directed V-shaped formation located between the nares, and a white, ovoid blotch on the upper operculum represents an autapomorphy (Ref. 94768).
Occurs among rocks along the shallow shores in a water depth of 10-40 cm with moderate to fast current in Mengmenghe River. Syntopic with Schistura cryptofasciata , Glyptothorax laosensis and Clarias sp.. Found also in Nanzhaihe River, characterized by water flow velocity of 0.5 m/s, 21 °C water temperature, and a pH of 5.4 (Ref. 94768).

Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
