简单描述
型态特徵 | 形态测量图
脊椎骨: 32 - 34. Diagnosis: Hyphessobrycon eilyos is distinguished from its congeners by the absence of humeral and caudal spots; by the presence of numerous dark chromatophores on the lateral surface of the body, with the chromatophores intensely concentrated on the ventral region from the pelvic-fin origin to the end of the caudal-fin base; dorsal, adipose, and caudal fins with carmine red pigmentation in life; the presence of 7-11 maxillary teeth; 6 or 7 horizontal scale rows between the dorsal fin origin and the lateral line; and 15 to 19 branched anal-fin rays. Detailed comparisons between H. eilyos and congeners sharing a general dark color pattern are presented in the "Discussion" (Ref. 52338).
鉴别: Hyphessobrycon eilyos 被与它的同类藉由缺少肱骨而尾部的斑点区分; 藉由有在身体的侧面表面上的很多深色的色素胞,与色素胞密集专注于尾鳍基底的腹区域从腹鳍起点到末端; 背部的, 用洋红色红色的颜色活着时的脂肪 , 与尾鳍; 那有 7-11 上颚齿; 在背鳍起源与侧线之间的 6 或 7 水平的鳞片列; 而且 15 到 19个分枝的臀鳍棘条。 在 H. eilyos 与分享一个一般的深色彩色斑纹的同类之间的详细比较在 " 讨论 " 出现。 (参考文献 52338)
