简单描述
型态特徵 | 形态测量图
脊椎骨: 31 - 34. Diagnosis: This species can be distinguished from all congeners by the presence of a single well-defined, round to horizontally oval humeral spot, similar to the one found in species of the Astyanax bimaculatus (Linnaeus) complex (vs. humeral spot absent, double, or variously developed, never round to horizontally oval). It can also be distinguished from its congeners, except H. reticulatus Ellis, by the combination of a reticulate dark pigmentation pattern, a broad, horizontally-elongate caudal-peduncle blotch, a narrow dark stripe extending along the central caudal-fin rays, 5 or 6 horizontal scale rows between the dorsal-fin origin and the lateral line, 4 or 5 horizontal scale rows between the lateral line and the pelvic-fin origin, and 15-20 branched anal-fin rays. Hyphessobrycon langeanii can be distinguished from H. reticulatus by the possession of a conspicuous, dark round to oval humeral spot (vs. relatively faint, vertically-elongate humeral spot), a horizontally-elongate caudal peduncle blotch (vs. vertically-elongate caudal peduncle blotch), the midlateral dark stripe relatively wide and faint (vs. midlateral dark stripe extremely narrow and well-defined), and infraorbitals 3 and 4 co-ossified (vs. separated) (Ref. 52338).
鉴别: 这种能被与所有的同类区分藉由有一很清晰, 水平椭圆形的肩部斑点的圆, 类似 Astyanax bimaculatus(林奈) 复合体的这一个被发现于的种.(vs. 肩部的斑点不存在, 加倍, 或各种不同地发展的, 从不圆的到水平椭圆形) 除了 H. reticulatus 埃利斯以外,它也能被与它的同类区分, 藉由网状深色的颜色图案的组合 , 宽, 水平地-细长的尾柄斑块, 一条延伸的狭窄深色的斑纹沿着中央的尾鳍鳍条 , 背鳍起源和侧线之间的 5 或者 6 水平的鱗片列 , 側線和腹鰭起點之間的 4 或者 5 水平的鱗片列，而且 15-20 分枝了臀鰭棘條。 Hyphessobrycon langeanii 能被與 H. reticulatus 區分被擁有對橢圓形的肩部斑點 (vs. 相當模糊又細長垂直的肩部斑點) 的一個顯著又深色的圓, 一水平地-延長尾柄斑塊 (vs. 細長垂直的尾柄斑塊), 側面中央的深色斑紋相當寬而模糊的 (vs. 側面中央的深色斑紋非常狹窄而且很清晰), 與眶下骨 3 與 4個共鈣化了 (vs. 分開).(參考文獻 52338)
