توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 11; شعاع نرم باله مخرجي: 29 - 36; مهره ها: 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).
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).
