Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10 - 11; Anal soft rays: 2 - 5. Short but high caudal fin. Cone-shaped head. Three pairs of barbels. Body covered by small round scales, no scale on the cheeks. Green gray in the body, yellowish stomach. A prominent black spot in the middle of the origin of caudal fin (Ref. 33389).

Adults inhabit streams on sand and gravel bottom (Ref. 26563). Length type refers to body length, assumed in TL.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00689 - 0.01912), b=3.08 (2.94 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

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. 59153): Low vulnerability (10 of 100).
