簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 4 - 7; 背的軟條 (總數): 8-10; 臀棘 1; 臀鰭軟條: 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).
在側面的條紋 48-52 上面的側線系列中的鱗片; 前背的鱗片 23-26. 超過 10.0 的標本公分 SL 被辨識特徵為細長的頭部，小的眼，狹窄的眼間骨, 長的吻與厚的尖前頜骨。 容易地與一些頭部形狀特徵的 O. piquava 與 O. mirinensis 區分了。 頭部下面輪廓幾乎是直的, 在 retroarticular 接合有時有一個輕微的中凸; 眼清楚地比吻的長度更小; 在頰部鱗片與身體鱗片上面與下面側面的條紋邊緣的網狀著色的圖案.(參考文獻 47314)
Occurs in exclusively freshwater lakes of the coastal laguna system (Ref. 47314).
