soft rays: 8;
Vertebrae: 25 - 26. This species is distinguished from its congeners by the following set of characters: predorsal scales 6; first dorsal fin without elongate and filamentous spine; fifth pelvic-fin ray unbranched, the basal membrane reduced; interorbital groove is shallow; interorbital space wide and bony width 75-77% of pupil diameter; absence of opercle scales; when fresh scale pockets with deep orange margins; when alive, 8 yellowish orange saddles over the dorsal midline and 6 saddles on the ventral midline (Ref. 91085).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00267 - 0.01297), b=3.10 (2.91 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
