Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 7; Rayons mous anaux: 6; Vertèbres: 26 - 27. Distinguished from other species of the genus by having the following characters: middle series of lateral plates truncated two plates before the caudal fin; inner margin of the pectoral-fin spine smooth, with no serrae; distal margin of the accessory flange of the first ceratobranchial pointed; mid-dorsal lateral series with 17-18 plates and continuous; abdomen usually with unplated areas anteriorly in adults; and males with preanal length 63.0-66.8% HL and 19-20 middle lateral plates (Ref. 87312).

Found on marginal vegetation (Ref. 87312).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.5 ±0.1 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
