Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 6 - 7; Anal soft rays: 4 - 6; Vertebrae: 36 - 38. Belongs to the Oreoglanis siamensis species group as it possesses a distinct median notch on the posterior margin of the lower lip. Can be distinguished from other members of the genus in having a combination of the following characters: short nasal barbel reaching to midway between its base and anterior orbital margin, maxillary barbel with rounded tip, length of adipose-fin base 30.7-38.1 % SL, caudal peduncle length 19.2-24.9 % SL, eye diameter 8.9-15.3 % HL, and a lunate caudal fin having upper and lower first principal rays of approximately equal length (Ref. 83406).

Occurs in rocky, fast-flowing streams (Ref. 83406).

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=0.00589 (0.00264 - 0.01315), b=3.08 (2.88 - 3.28), 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).
