Diagnosis |
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). |
