Rayons mous anaux: 192 - 213. Distinguished by having the following combination of characters: depth of the caudal filament 3.3-4.8% CL; length of the caudal filament 28.6-46.1% LEA; length of the coronomeckelian bone 50% or more the length of Meckel’s cartilage; length of the posterior ceratohyal approximately the same length as the ventral hypohyal; gape relatively long and the rictus extending posteriorly beyond the vertical through the posterior naris; teeth between seven and ten irregularly distributed on the internal surface of the endopterygoid; anteroposterior length of premaxilla greater than the transverse width; teeth on the dentary restricted to the anterior one-half or slightly more of the dorsal margin; 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; 19-21 pectoral-fin rays; and 192-213 anal-fin rays (Ref. 93148).
Occurs in swift-flowing water habitats. Also found in main stream of shallow rapids and
small waterfalls, always over a rocky bottom (Ref. 93418).
