简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 11; 臀鳍软条: 11. The presence of three conspicuous black blotches on the base of the dorsal, anal, and caudal fins separates this species from all characid species. Distinguished from all other species of the Cheirodontinae by two uniquely derived characters, the anteriormost proximal radial of the anal fin with an anteriorly extended lamina entering the abdominal cavity, between the distal portions of the 12th to 14th pleural ribs and by the extremely elongate caudal peduncle 27.3-30.2% SL. Can be further diagnosed by having ventral procurrent caudal-fin rays 7-9 and hemal spines of one, two or sometimes three posterior caudal vertebrae directly articulating with the ventral procurrent caudal-fin rays (Ref. 79887).
Body shape (shape guide): elongated.
The type locality has slow current, muddy substratum, and silty, turbid water with abundant riparian vegetation and with maximum depth of 1.3 m. Also collected in a perceptible current with some submerged vegetation, transparent water, sandy and muddy substratum and riparian vegetation (Ref. 79887).
