背的软条 (总数) : 11; 臀鳍软条: 29 - 36; 脊椎骨: 40 - 44. Diagnosis: Differs from its congeners except B. magoi 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 44-48, modally 47 (vs. >57 in alburnoides, <31 in disruptus and durbini, and 43-47, modally 44 or 45 in magoi); 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 4.2-5.4%, mean 4.7% (vs. 5.8-8% SL, mean 6.8% in magoi); length of anal fin base 27.3-29.8% SL, mean 28.8% (vs. 24.8-27.9%, mean 26.6% in magoi); and total vertebrae 42-44, modally 43 (vs. 40-42, modally 41-42 in magoi) (Ref. 56366).
鉴别: 用它的独特彩色斑纹除了 B. magoi 以外有别于它的同类, 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 44-48, 典型地 47;(vs.>57 在 alburnoides 中, <31 在 disruptus 与 durbini 中, 与 43-47, 典型地 44 或 45 在 magoi 中) 有细孔的侧面鳞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 4.2-5.4%, 意謂 4.7%;(vs.5.8-8% SL, 平均的 6.8% 在 magoi 中) 臀鰭基底 27.3-29.8% SL 的長度, 意謂 28.8%;(vs.24.8-27.9%, 平均的 26.6% 在 magoi 中) 而且總脊椎骨 42-44, 典型地 43(vs.40-42, 典型地 41-42 在 magoi 中).(參考文獻 56366)
Found in habitats with moderate to fast moving waters over rocky and sandy bottoms; in both acidic, black waters, as well as in clear, but slightly acidic waters. In the Caura, it was found in rapids covered by vascular plants (Podostemonacae), as well as in small springs with sandy bottoms. Found in the upper part of the water column in the main channel, usually in schools with other characid species. Observed food items include several groups of terrestrial insects (Ref. 56366).
发现于栖息地在岩质与砂质底部上的有中等的到快速流动的水域了; 在酸性又黑色的水域中, 以及在清澈的, 但是些微酸性的水域。 在 Caura 中，它被发现于被维管束植物 (Podostemonacae) 盖着的急流, 以及在小的泉水且底部为沙地的地方。 在主要的峡道中发现于水团的上半部了, 通常成群聚集与其它的脂鲤科鱼类种在一起。 观察食物组成包括一些群体的陆栖昆虫。 (参考文献 56366)
