Short description Morfología | Morfometría

Radios blandos dorsales (total): 12; Radios blandos anales: 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).

Biología     Glosario (por ej. epibenthic)

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).
