(total): 15 - 17;
soft rays: 6 - 7;
Vertebrae: 26. Differs from all species of the genus by the following combination of characters: 5-6 anal-fin spines; 6-7 branched anal-fin rays; caudal peduncle length 8.9-11.8% of SL; lips not thickened; in preserved specimens lateral band formed by two series of scales, each scale bears a dark spot in the centrum, between both scales there is a light narrow area; dorsal, anal and caudal fins, and opercle without dark spots (Ref. 57794).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00598 - 0.04201), b=2.99 (2.76 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
