背棘 (总数) : 4; 背的软条 (总数) : 9; 臀棘: 3; 臀鳍软条: 5. Distinguishable from other species of the genus by the combination of the following characters: color pattern consisting of a blackish longitudinal stripe along side of body; more lateral line scales (34-35) and predorsal scales (14); median lobe of lower lip with a truncate posterior margin, not extending to a line connecting inner corners of mouth; eye diameter smaller (13.1-13.8% of HL, vs. 14.6-31.2%) and visible in ventral view; interorbital width wider (43.8-45.7% of HL, vs. 27.8-40.0%); isthmus naked, scales embedded in skin; gill rakers 19-22 (Ref 13848).
可与其他种的本属区别藉由下列特征的组合: 包含一条黑色的纵向斑纹的彩色斑纹沿着身体侧边; 更多的侧线鳞片 (34-35) 与前背的鳞片;(14) 下唇的中动脉叶具有一个截形的后缘, 不延伸至连接嘴的内角的一条线; 眼直径比较小的 (13.1-13.8% 的 HL, vs.14.6-31.2%) 与看得见的由腹面观之; 眼间骨宽度比较宽的;(43.8-45.7% 的 HL, vs.27.8-40.0%) 峡部裸露的, 插入皮肤的鳞片; 鳃耙 19-22(参考文献 13848).
Found in streams with clear water and usually with slow current (Ref. 13848).
发现于溪流了，水质清澈的地方而且通常有和缓的水流。
