Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 25; Anal soft rays: 35. This species of the subgenus Biradiostomias is distinguished by the following characters: a leaf-like terminal extension of the chin barbel, the distal third with a single oval bulb with a small papillary terminal appendage and with a patch of pigmentation at the base; ventral edge of the bulb is laterally compressed, sharp; inner trunk of the barbel with loose melanophoric pigmentation and disappearing at the border with terminal expansion; total vertebrae 68; absence of formed dorsal subcutaneous spots (Ref. 126203).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.8 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
