背棘 (总数) : 1; 背的软条 (总数) : 6 - 7; 臀鳍软条: 10 - 11; 脊椎骨: 34 - 36. Presence of 4-5 serrations along posterior edge of pectoral spine; iii-iv,7-8 anal-fin rays (total 10-11), and a more deeply forked caudal fin with regularly tapering lobes. Differs further from other Indochinese congeners in possessing fewer vertebrae (34-36 vs. 38-41); a deeper body (depth at anus 15.2-16.9% SL vs. 9.8-15.1) and equal upper and lower jaws (vs. longer and weakly-projecting lower jaw) (Ref. 37785).
Body shape (shape guide): elongated; Cross section: circular.
脂鳍的后缘圆的; 脂鳍基底 (18.5-20% SL), 与尾鳍的最初几前流鳍条接触。 在肛门 15.2-16.9% SL 的体高; 头部深度 11.9-15.8% SL; 眼小的, 背外侧地位于与皮下的, 直径 4.3-6.6% HL; 背鳍到脂鳍距离 20.6% SL; 尾柄 13% SL 的深度。 尾鳍叶略微在后部地圆的, 藉由上叶长度超过低的。 具有上颌与下颌的嘴与口裂终点等于; 唇肉质的而且些微地有毛缘的, 在用下叶被包含在嘴角被参加的大而膜状的上叶的眼的前缘之下有发展良好的 rictal 摺层。 此鱼种在有一个方面有别于它的同类强烈扁平的头部;(vs.8.8-15.8% SL) 强烈地-突出的下颌;(vs. 非或弱-突出的颌) 20个主要的尾鳍鳍条.(vs.17) 在有一个方面有别于它的同类较小的大小 (4.53 公分 SL 和至少比较的极大 6 公分) 。 (参考文献 37785)
Collected from a side arm of the main river in Xe Bangfai, among a gravel bed in the floodplain, in shallow water (less than 30 cm) and in Xe Pon, among stones and boulders in rapids (Ref. 37785).
在 Xe Bangfai 采集自主要河的一个支流了, 存在一个砾石床在洪泛区中, 在浅水区 (少于 30 公分) 与 Xe Pon 中, 在石头与大圆石之中在急流中.(参考文献 37785)
