背的软条 (总数) : 12; 臀鳍软条: 8. Differs from its congeners in Indochina by the combination of the following characters: wide median incision in upper lip; distance between anus and anal fin origin 2.6-3.8 eye diameter; pelvic fin clearly reaching beyond anus; caudal fin deeply emarginate; body with 7-11 dark bars, wider than interspaces, regularly shaped and set, meeting their homologues on back; black bar at caudal-fin base complete, reaching dorsal and ventral midlines (Ref. 40772).
在印度支那有别于其他本属的种藉由下列特徵的组合: 在上嘴唇中的宽中央的切口; 肛门与臀鳍起源 2.6-3.8 眼直径之间的距离; 清楚地超过肛门的腹鳍; 尾鳍边缘深凹; 身体有 7-11 深色的横带,比间隙宽, 经常形状与组, 碰到他们的同系物背面; 在尾鳍基底的黑色横带完全的, 达到背部与腹的中线.(参考文献 40772)
Abundant in streams and rivers with gravel or rocky substrate and high water velocities (Ref. 40772). Resistant to organic pollution and can survive in streams that flow through villages and towns and exhibit strong signs of human perturbation (Ref. 40772). Most abundant in riffles and rapids with current velocities more than 1 m/s below the surface (Ref. 40772). Found in small high gradient rivers and small mountain streams, as well (Ref. 40772). Often associated with Poropuntius sp., Annamia normani, Schistura dalatensis and Glyptothorax laosensis (Ref. 40772).
丰富的在溪流与河川中、底部为砂砾石或岩石且水流快速的地方.(参考文献 40772) 对有机污染有抵抗性而且在流过村庄与城镇，而且被人类强烈扰乱的溪流中能存活.(参考文献 40772) 在表面之下的最丰富在急流与急流以水流速度超过 1个公尺/秒.(参考文献 40772) 发现于高落差的小型河川与小的山地溪流了, 也。 (参考文献 40772) 时常伴随着 Poropuntius sp. ， Annamia normani ， Schistura dalatensis 与 老挝纹胸 ［Glyptothorax laosensis］ .(参考文献 40772)
