It can be distinguished from all other congeners by having the following combination of characteristics： maxillary barbels length is 78.3-90.4% of rostral barbels length; pelvic-fin length is 83.7-89.4% of the distance between the ventral-fin origin and to the anal-fin origin; a longitudinal wide black stripe running along the posterior lateral line and irregular brown pigments on the sides of the body.展开更多
