简单描述
型态特徵 | 形态测量图
背棘 (总数): 4 - 7; 背的软条 (总数): 8-10; 臀棘 1; 臀鳍软条: 15 - 18; 脊椎骨: 47 - 49. Scales in lateral line series above lateral band 48-52; predorsal scales 23-26. Specimens over 10.0 cm SL are recognized by the elongate head, small eyes, narrow interorbital, long snout and thick pointed premaxilla. Easily distinguished from O. piquava and O. mirinensis by several head shape characters. Ventral head profile nearly straight, sometimes with a slight convexity at the retroarticular joint; eyes clearly smaller than snout length; reticulate pigmented pattern in the border of check scales and body scales above and below lateral band (Ref. 47314).
在侧面的条纹 48-52 上面的侧线系列中的鳞片; 前背的鳞片 23-26. 超过 10.0 的标本公分 SL 被辨识特徵为细长的头部，小的眼，狭窄的眼间骨, 长的吻与厚的尖前颌骨。 容易地与一些头部形状特徵的 O. piquava 与 O. mirinensis 区分了。 头部下面轮廓几乎是直的, 在 retroarticular 接合有时有一个轻微的中凸; 眼清楚地比吻的长度更小; 在颊部鳞片与身体鳞片上面与下面侧面的条纹边缘的网状着色的图案.(参考文献 47314)
Occurs in exclusively freshwater lakes of the coastal laguna system (Ref. 47314).
