簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 10; 臀鰭軟條: 14 - 16; 脊椎骨: 35. Bryconamericus pinnavittatus is distinguisged from all congeners, except B. bolivianus, B. cismontanus, B. deuterodonoides, B. grosvenori, B. hyphesson, B. lambari, B. macrophthalmus, B. ornaticeps, B. patriciae, B. rubropictus, B. tenuis, and B. thomasi, by having 11-13 branched anal-fin rays (vs. 15 or more). It can be diagnosed from B. bolivianus, B. deuterodonoides, B. grosvenori, B. hyphesson, B. lambari, B. ornaticeps, B. patriciae, B. rubropictus, B. tenuis, and B. thomasi by having two maxillary teeth (vs. three or more), from B. cismontanus by having four outer premaxillary teeth (vs. 5 or 6), and from B. macrophthalmus by having 34-38 perforated lateral-line scales (vs. 40-41) (Ref. 99308).
