This species is distinguished with the following characters: short head, nearly as broad as long; blunt snout, well-rounded in lateral profile and dorsally; palatal tooth patches posterior to premaxillary tooth band meet at midline; rounded caudal-fin lobes, of near equal length, fin not deeply forked; short and thick caudal peduncle; underside of body (both head and belly) covered with fine brown specks; anterior gill-rakers on first arch 10-13 (5 + 5); pectoral fin rays 9-12; fatty growth along pectoral fin spines of breeding females not present outside spawning season. Dimorphism present with posterior (humeral) process of cleithrum obvious externally, fan-shaped in females, triangular in males; smooth and shallow dorsomedian cranial depression on exposed skull not reaching supraoccipital process (Ref. 85159 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00427 (0.00167 - 0.01091), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.6   ±0.48 se; based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (35 of 100). Price category (Ref. 80766 ):   Medium .
