Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 7; Anal soft rays: 4. This species is distinguished from its congeners by the following characters: vertebrae 12-14 from first neural spine not including hypural plate (vs. 8-11); it differs from all (except murinus) by having yellowish bars on tip of dorsal and caudal fins; differs from immaculatus and zuanoni by the small yellowish dots covering the body (vs. color pattern uniform, without dots or large white spots, respectively); differs from tocantinensis by having the rounded dorsal profile of snout (vs. snout pointed); differs from murinus by the presence of a bar-shaped eversible opercle with conspicuous
odontodes (vs. triangle-shaped opercle not eversible, no conspicuous odontodes) and by the presence of 4 unbranched anal-fin rays (vs. 3) (Ref. 95496).

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00719 - 0.03336), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
