Diagnosis: Differs from its congeners, except collettei, by its unique color pattern, red coloration at the upper half of a diffuse caudal fin ocellus. Further distinguished from other species of the subgenus Bryconops by the following characters: pored lateral scales 43-47, modally 44 or 45 (vs. >57 in alburnoides, <31 in disruptus and durbini, and 44-48, modally 47 in collettei); pored lateral scales extending 2-3 scales beyond end of hypural plate onto caudal fin rays (vs. caudomaculatus, it reaches end of hypural plate and not onto caudal fin rays); snout length 5.8-8% SL, mean 6.8% (vs. 4.2-5.4%, mean 4.7% in collettei); length of anal fin base 24.8-27.9%, mean 26.6% (vs. 27.3-29.8% SL, mean 28.8% in collettei); and total vertebrae 40-42, modally 41-42 (vs. 42-44, modally 42-43 in collettei) (Ref. 56366).
鉴别: 除了 collettei 以外，有别于它的同类, 用它的独特彩色斑纹, 在扩散尾鳍眼状斑的上半部的红色颜色。 进一步区分了其他种的亚属 Bryconops 藉由跟随特征: 有细孔的侧面鳞片 43-47, 典型地 44 或 45;(vs.>57 在 alburnoides 中, <31 在 disruptus 与 durbini 中, 与 44-48, 典型地 47 在 collettei 中) 有細孔的側面鱗片在尾鰭鰭條之上延伸 2-3個鱗片超過尾下碟的末端;(vs. caudomaculatus ，它在尾鰭鰭條之上達成尾下碟的末端而不是) 吻的長度 5.8-8% SL, 意謂 6.8%;(vs.4.2-5.4%, 平均的 4.7% 在 collettei 中) 臀鰭基底 24.8-27.9% 的長度, 意謂 26.6%;(vs.27.3-29.8% SL, 平均的 28.8% 在 collettei 中) 而且總脊椎骨 40-42, 典型地 41-42(vs.42-44, 典型地 42-43 在 collettei 中).(參考文獻 56366)
Collected from a morichal with fast moving waters over sandy bottoms; often in water from mid-depth to the surface, at the center of the main channel, where it schools with other characid species. Feeds at the surface and attracted to allotochtonus material that falls into the water; also on several groups of terrestrial insects (Ref. 56366).
用快速流动的水域沙质底部之上采集自 morichal了; 常见于水中从在-之中对表面的深度, 在主要峡道的中心, 在那里它与其他的脂鲤科鱼类种集结成群。 为食在水表面而且被掉入水中的 allotochtonus 材料吸引; 也在一些群体的陆栖昆虫身上.(参考文献 56366)
