简单描述
型态特徵 | 形态测量图
Diagnosis: Distinguished from its trans-Andean congeners by the following: unmodified, completely pored lateral line-scales; absence of a distinct patch of dark pigmentation on the basal portions of the caudal fin; absence of a stripe of dark pigmentation along the middle rays of the caudal fin; relatively wide third infraorbital; straight to slightly convex predorsal profile; caudal peduncle depth 11.31-13.42% of SL; possess 10 to 12 branched anal-fin rays and 36 to 38 lateral-lines scales. This species differs from its congeners by the following: distance from the dorsal-fin origin to the pelvic-fin origin 26.7-34.1% of SL; rotund or somewhat vertically-elongate humeral mark; reticulate pattern of dark pigmentation on the dorsal portion of body; maxilla with a thick anterior process; robust posterior portion and a distinct flexion in the region where it extends past the posterior limit of the premaxilla; absence of a bony plate on the dorsal surface of fourth basibranchial; presence of one or more teeth on the third infrapharyngobranchial; dorsolateral portion of the dilatator groove that is roofed to varying degrees by processes from the frontal and pterotic; and, absence of a narrow ring-like process of the scapula forming the anterior border of scapular foramen (Ref. 55562).
鉴别: 与它的 trans-安第斯山脉的同类区分了藉由跟随: 不变异的, 完全地有孔的侧线-鳞片; 在尾鳍的基部部分上缺乏一个深色颜色的明显小区块; 缺乏一条深色颜色的斑纹沿着尾鳍的中央鳍条; 相当宽的第三眶下的; 对些微中凸前背的轮廓直线; 尾柄深度 11.31-13.42% 的 SL; 持有 10 到 12个分枝的臀鳍棘条与 36 到 38个侧线鳞片。 这种有别于它的同类藉由跟随: 来自背鳍起源到腹鳍起点的距离 26.7-34.1% 的 SL; 圆的或略微细长垂直的肱骨标志; 在身体的背部部分上的深色顏色的網狀圖案; 顎骨具有一個厚的前面突起; 在區域中的結實在後部的部分與一個明顯的彎曲在那裡它越過前頜骨的後面的限制延伸; 在第四個基鰓骨的背部表面上缺乏一個多骨的碟; 有一個或多個牙齒在第三個下咽鰓骨; dilatator 凹槽的背外側部分，那是蓋屋頂到改變突起從額骨與 pterotic 的程度; 並且, 缺乏形成肩胛孔的前緣的肩胛的一個狹窄像環一樣突起.(參考文獻 55562)
