背棘 (总数) : 4 - 6; 背的软条 (总数) : 7 - 9; 臀棘: 1; 臀鳍软条: 16 - 20; 脊椎骨: 47 - 49. Scales in lateral series above lateral band 47-53; and predorsal scales 24-26 (Ref. 47314). Differs from O. bicudo and O. ledae by the following characters: thin fragile premaxilla, not projected anteriorly in its medialmost portion; ventral head profile usually split into two straight sections, forming an angle at the retroarticular joint; snout short, as long as wide in dorsal view; mouth slightly upturned in lateral view and positioned above a horizontal line crossing near the center of eye and above a horizontal line crossing near the middle of head depth (Ref. 47314).
Body shape (shape guide): elongated.
在侧面的条纹 47-53 上面的侧线列中的鳞片; 而且前背的鳞片 24-26.(参考文献 47314) 在特徵之后有别于 O. bicudo 与 O. ledae 藉由: 细的纤细前颌骨, 不在它的 medialmost 部分中前面地突出; 头部下面轮廓通常分割为二个直的部分,在 retroarticular 接合形成一个角; 吻短又长达广泛的在中背面; 嘴些微朝上在侧面中而且在上面在眼的中心附近的一个水平线横越而且在头部深度的中央附近的一个水平线横越之上放置.(参考文献 47314)
Occurs exclusively in freshwater (Ref. 47314).
专门地生存在淡水中。 (参考文献 47314)
