背棘 (總數) : 0; 背的軟條 (總數) : 10; 臀棘: 0; 臀鰭軟條: 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).
嘴新月形成。 沒有小瘤的, 不沒有自由邊緣的薄膜的發展良好的下巴。 唇發展良好的, 低的有兩個側面的部份與 1個中央的分成兩葉的部份。 喙葉無小齒的邊緣而不是發展良好的。 顎些微有角但是沒有刃口。 沒有鱗片背面在背鰭之前。 黑色的背面，有斑點的側邊, 清澈的腹面。 側線的前面鱗片, 深色或黑色的。 緊鄰, 在這一個鱗片之前在鰓裂的上面角落是一個小的紅色區域。 在基部部份上的 4個斜的標誌背部的。
At first sight this species resembles Barbus because of his non-denticulated rostral lobe and his small non-tuberculated disc (Ref. 2940).
與 Barbus 相似乍看之下由於無小齒的喙葉與小的沒有小瘤的下巴。
