Short description Claves de identificación | Morfología | Morfometría

Vértebra: 35. Absence of dark stripes on body; absence of concentric bands on paired fins. Pelvic fin reaching 5-40% of distance between anus and anal-fin origin. No cavity around the mouth, skin-fold between oropectoral membrane and ventral surface of head running from pectoral-fin origin to second rostral barbel. Tubercles on dorsal part of head concentrated on tip of snout; 15-21 large tubercles on branched pectoral-fin rays. General appearance elongated. Lateral line with 58-64 scales (Ref. 40433).

Very rheophilous, caught in only in rapids with current velocity exceeding 1 m/sec together with other rheophilous fish such as species of Garra, Annamia, Hemimyzon, Homaloptera, Schistura and Nemacheilus. Feeds on aquatic invertebrates (Ref. 40433).

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=0.00617 (0.00268 - 0.01421), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.5 ±0.37 se; based on food items.

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