Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 11; Anal soft rays: 8. One barbel-shaped papilla at the corner of mouth; pelvic fins not fused; distance between last pelvic-fin rays 2.7-4.0 times in body width at pelvic-fin origin; 13-14/10-12 pectoral-fin rays; 6-7/10-13 pelvic-rays and 59-64+1-2 lateral line scales (Ref. 42935).

Collected from a small river about 60 m wide, with a succession of rapids over rocks and deep pools over sandy bottom. Caught in rapids with a current velocity exceeding 1 m/s with other rheophilous fish (species of Garra, Annamia, Hemimyzon, Homaloptera, Schistura, and Nemacheilus (Ref. 42935).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00631 (0.00265 - 0.01501), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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