簡短描述
型態特徵 | 形態測量圖
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 與 H. erythrostigma(Fowler) 以外, Hyphessobrycon hamatus 被與本屬的所有種區分, 藉由在背部上有小的多骨鉤, 雄性的臀鰭、腹鰭、與胸鰭。 新種有別於在臀鰭棘條 (iii-v,16-18, 平均=17, n=28) 和 (iv,28-30 與 iv,27-29, 分別地) 比較的下面數字中的 H. socolofi 與 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。
