简单描述

背的软条 (总数) : 11; 臀鳍软条: 21 - 24; 脊椎骨: 37 - 38. Distinguished from all Hyphessobrycon species by the following characters: 7-8 tricuspid teeth in the inner premaxillary tooth row; 5-9 tricuspid teeth in maxilla; 18-21 anal-fin branched rays; small dark spot centered on the basal portion of the median caudal-fin rays, sometimes extending to their distal portions; humeral spot and longitudinal stripe absent; male pelvic fins with hooks; hooks sometimes present in the anal fin (Ref. 54770).
与所有的 Hyphessobrycon 种区分了藉由跟随特征: 在内部的上颌骨前的齿列中的 7-8 三尖齿; 在颚骨中的 5-9个三尖齿; 18-21个臀鳍分支条; 小的深色斑点在中央尾鳍鳍条的基部部分上集中了, 有时延伸至他们的远程部份; 肩部的斑点与纵向的斑纹不存在; 雄鱼腹鳍有钩; 钩在臀鳍中有时候有。 (参考文献 54770)
