背棘 (总数) : 1; 背的软条 (总数) : 6; 臀鳍软条: 15; 脊椎骨: 41. Differs from all members of the genus by the unique combination of the following characters: posterior edge of adipose fin rounded; body depth at anus 11.5% SL; head depth 8.3% SL; eyes small, dorsolaterally situated and subcutaneous, diameter 4.8% HL; 41 vertebrae, lower jaw strongly projecting; forked caudal fin. Distinguished from all Indochinese congeners in having a strongly depressed head (depth 8.3% SL vs. 8.8-15.8) with lower jaw strongly- projecting (vs. non- or weakly-projecting); and 20 principal caudal-fin rays (vs. 17). Can be differentiated from A. mucronatum, A. foratum, and A. variegatum in having a smaller eye diameter (4.8% HL vs. 5.1-8.5% HL) (Ref. 37785).
脂鳍的后缘圆的; 长的脂鳍基底 (28.9% SL), 与尾鳍的最初几前流鳍条接触。 在肛门 11.5% SL 的体高; 头部深度 8.3% SL; 眼小的, 背外侧地位于与皮下的, 直径 4.8% 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。 具有下颌的嘴与口裂终点略长于上面的而且强烈地向前突出; 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;(对 8.8-15.8% SL) 强烈地-突出的下颌;(对非或弱-突出的颌) 20个主要的尾鳍鳍条.(对 17) 在有一个方面有别于 A. mucronatum ， A. foratum 与 A. variegatum 较小的眼直径 (对 5.1-8.5% HL) 。 (参考文献 37785)
Specimens were obtained from villagers fishing with cast-nets and harpoons among large boulders; thus, actual habitat unknown. However, the stream in the area of occurrence is with swift to fast current among large boulders, or small cascades, and further downriver, current is quieter, over large stones and gravel (Ref. 37785).
标本用在大圆石之中的抛网与鱼叉被从钓鱼的村民获得; 因此, 真实的栖息地未知。 然而，在发生的区域的水流是对在大圆石, 或小的小瀑布, 与进一步的下游河川之中的快速水流有迅急的, 水流比较安静, 在大的石头与砾石之上.(参考文献 37785)
