背棘 (总数) : 0; 背的软条 (总数) : 10; 臀棘: 0; 臀鳍软条: 8. Diagnosis: Garra allostoma is an insectivorous Garra with a terminal or subterminal mouth and curved or crescentic mouth opening superficially resembling a generalized Barbus; cheek below eye laterally expanded; rostral cap reduced, smooth; mental disc smooth, non tuberculate, posterior border bound to isthmus; upper and lower lips well developed; lower lip non-tuberculate, divided into distinct, lateral and medial portions by a constriction; medial portion of lower lip constricted near symphysis, so that it is bilobate; horny sheaths of upper and lower jaws not greatly enlarged, without trenchant cutting edge; pharyngeal teeth in two rows, 2 or 3,5 (Ref. 96454). Absence of rostral fimbriae distinguished Garra allostoma from all other Garra, and having only two instead of three pharyngeal tooth rows distinguished it from all others for which the number of rows has been reported (Ref. 96454).
Body shape (shape guide): elongated.
嘴新月形成。 没有小瘤的, 不没有自由边缘的薄膜的发展良好的下巴。 唇发展良好的, 低的有两个侧面的部份与 1个中央的分成两叶的部份。 喙叶无小齿的边缘而不是发展良好的。 颚些微有角但是没有刃口。 没有鳞片背面在背鳍之前。 黑色的背面，有斑点的侧边, 清澈的腹面。 侧线的前面鳞片, 深色或黑色的。 紧邻, 在这一个鳞片之前在鳃裂的上面角落是一个小的红色区域。 在基部部份上的 4个斜的标志背部的。
At first sight this species resembles Barbus because of his non-denticulated rostral lobe and his small non-tuberculated disc (Ref. 2940).
与 Barbus 相似乍看之下由于无小齿的喙叶与小的没有小瘤的下巴。
