Max length : 31.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 27732)
Distinguished from burmanicus in having 37-39+3 lateral line scales; 11-12 branched dorsal rays and 7+1/2 scale rows between lateral line and dorsal fin origin. Reaches 31 cm SL.
Body shape (shape guide): elongated.
与 burmanicus 有 37-39+3个侧线鳞片区分了; 在侧线与背鳍起点之间的 11-12个分枝的背鳍鳍条与 7+1/2 鳞片列。 范围 31 公分 SL。
Occurs in fast flowing, clear waters with stony substrate (Ref. 27732). Found in clear mountain streams usually under complete forest canopy (Ref. 12693). Encountered in rapid-running mountain streams of the middle Mekong (Ref. 12975). Feeds mainly on insect larvae along with small amounts of detritus and periphyton. Apparently breeds after the end of the rainy season after water levels in upland areas have declined, and juveniles appear in catches during April. Not seen in markets (Ref. 12693).
用多石底部出现于快速流动又清澈的水域 (. 参考文献 27732) 在完全的森林覆盖下面通常发现于清澈的山地溪流了。 (参考文献 12693) 在湄公河中游的湍急山地溪流中见到了。 (参考文献 12975) 主要吃昆虫幼生以及少量的碎屑与固着生物。 显然地繁殖已经在高地的区域的水位后的雨季的末端之后消退，而且稚鱼在四月期间在捕获中出现。 不在市场中见到。 (参考文献 12693)
