简单描述
检索表 | 型态特徵 | 形态测量图
Hyphessobrycon hamatus is distinguished from all species of the genus, except H. socolofi Weitzman and H. erythrostigma (Fowler), by the presence of small bony hooks on the dorsal, anal, pelvic, and pectoral fins of males. The new species differs from H. socolofi and H. erythrostigma in the lower number of anal-fin rays (iii-v, 16-18, average=17, n=28) versus (iv, 28-30 and iv, 27-29, respectively), and by the absence of a black spot on dorsal fin versus the presence of such pigmentation.
除了 H. socolofi Weitzman 与 H. erythrostigma(Fowler) 以外, Hyphessobrycon hamatus 被与本属的所有种区分, 藉由在背部上有小的多骨钩, 雄性的臀鳍、腹鳍、与胸鳍。 新种有别于在臀鳍棘条 (iii-v, 16-18, 平均=17, n=28) 和 (iv, 28-30 与 iv, 27-29, 分别地) 比较的下面数字中的 H. socolofi 与 H. erythrostigma, 與藉由缺少一個黑色的斑點在背鰭 和 比較上那有如此的顏色。
