臀鳍软条: 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).

50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00172 - 0.00768), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
