Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 14; Anal spines: 0; Anal soft rays: 9. 2-3 small black spots on last simple dorsal-fin ray; dark blotch at base of simple and first two branched dorsal-fin rays; head spotted; color pattern with 8-13 dark blotches along lateral line, reaching venter in most specimens; no conspicuous black stripe along lateral line or along mid-dorsal longitudinal line; caudal peduncle elongated, 1.9-2.4 times longer than deep; no acuminate scales on caudal peduncle; distinct median incision in upper lip.
Adult specimens have been collected in fast-flowing rivers with rock or large-sized gravel substratum; juveniles from sandy substratum in moderate current.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00347 - 0.01512), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 2.7 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
