Short description
Hình thái học | Sinh trắc học
Tia mềm vây hậu môn: 190 - 222. Distinguished from other congeners by having the following combinations of characters: length of the gape with the rictus falling short of the vertical through the posterior naris; the length of the coronomeckelian bone 50% or more the length of Meckel’s cartilage; the length of the posterior ceratohyal approximately the same length as the ventral hypohyal; 10-14 scales above the lateral line at the midbody; the form of the premaxilla with the anteroposterior length greater than the transverse width; the distribution of the teeth on the dentary restricted to anterior one-half or slightly more of the dorsal margin; five or six teeth arranged in single row on the internal surface of the endopterygoid; presence of a narrow dark stripe along the lateral line and a broad band of dusky to dark pigmentation overlying the basal pterygiophores of the anal fin; 18-21 pectoral-fin rays; 190-222 anal-fin rays (Ref. 93148).
The type locality, Rio Mucajaí, is characterized by rapid flowing water and a 20 m high waterfall. The species was encountered above these falls in an area with many rapids and no still backwaters (Ref. 93148).
