Diagnosis: outer teeth of jaws in females and young males bicuspid except a few lateral unicuspids, but mature males with many unicuspids, until at about 20cm SL nearly all outer teeth are unicuspid and the posterior are enlarged; pharyngeal teeth fine and dense, with blade of lower pharyngeal bone longer than toothed area; 21-26 gill-rakers on lower part of first arch; 29 vertebrae; 15-16, rarely 17 dorsal spines; total dorsal rays 27 or 28; caudal fin not scaly; genital papilla in both sexes complex, in the male elongate, bifid and tasselled; white spots on pelvic fins of mature males and on dorsal, anal and base of caudal in both sexes; dentition and coloration of mature males diagnostic (Ref. 2).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00707 - 0.03721), b=3.02 (2.82 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100) .
