Morphology | Morphometrics
soft rays: 8. Distinguished from other congeners by the following unique combination of characters: last simple ray of dorsal fin flexible and unserrated; squamation: lateral-line scales always 41-44 (modally 42) and predorsal scales 12-14 (modally 12); maxillary barbels 9.7-12.4 % (mean 11.2 %) in head length; rostral cap with thick upper lip and lower part of upper lip exposed; and coloration of young individuals (<75 mm SL) with random grayish-black spots near lateral-line scales (Ref. 92993).
This species occurs in small tributaries in mountain areas where it inhabits running brooks with large rocks as well as slow-flowing pool with pool bed consisting of mud and aquatic plants (Ref. 92993).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00249 - 0.01394), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
