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.
與 burmanicus 有 37-39+3個側線鱗片區分了; 在側線與背鰭起點之間的 11-12個分枝的背鰭鰭條與 7+1/2 鱗片列。 範圍 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).
用多石底部出現於快速流動又清澈的水域 (. 參考文獻 27732) 在完全的森林覆蓋下面通常發現於清澈的山地溪流了。 (參考文獻 12693) 在湄公河中游的湍急山地溪流中見到了。 (參考文獻 12975) 主要吃昆蟲幼生以及少量的碎屑與固著生物。 顯然地繁殖已經在高地的區域的水位後的雨季的末端之後消退，而且稚魚在四月期間在捕獲中出現。 不在市場中見到。 (參考文獻 12693)
