簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 12 - 13; 臀鰭軟條: 9; 脊椎骨: 33. Belongs to a group of species, including Characidium xavante, distinguished uniquely by having high number (12-18) of dark, vertical bars on the body, each bar having the width of a scale. Differs from Characidium xavante by a greater number of scales
around the caudal peduncle (12 vs. 10), narrower interorbital region (interorbital distance 20.5-28.6 vs. 30.1-38.0% HL) and deeper caudal peduncle (caudal peduncle depth 46.2-57.8% vs. 35.4-44.9% HL). Additional conspicuous external characters which are not unique but are
useful in the identification of this species include absence of adipose fin, incomplete lateral line, and presence a dark blotch on the caudal peduncle (Ref. 75787).
