Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6-7; Anal soft rays: 10 - 11; Vertebrae: 34 - 36. Presence of 4-5 serrations along posterior edge of pectoral spine; iii-iv,7-8 anal-fin rays (total 10-11), and a more deeply forked caudal fin with regularly tapering lobes. Differs further from other Indochinese congeners in possessing fewer vertebrae (34-36 vs. 38-41); a deeper body (depth at anus 15.2-16.9% SL vs. 9.8-15.1) and equal upper and lower jaws (vs. longer and weakly-projecting lower jaw) (Ref. 37785).

Collected from a side arm of the main river in Xe Bangfai, among a gravel bed in the floodplain, in shallow water (less than 30 cm) and in Xe Pon, among stones and boulders in rapids (Ref. 37785).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00575 (0.00254 - 0.01302), b=3.05 (2.85 - 3.25), 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

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months ().

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