Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10; Anal 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00299 - 0.01530), b=3.12 (2.93 - 3.31), 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.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
