soft rays: 8. Dark bands lacking a pale central area; width of pale bands clearly less than width of dark bands; pattern on cheek consisting of numerous spots between posterior end of maxillary and preopercular margin, spots often separated by lines of pigment in light areas between spots; pectoral-fin base with two spots, a larger spot on ventral portion of base and a smaller spot on dorsal portion of base; pectoral fin rays modally 15 (Ref. 34188).
Collected from large rocks covered with algae, sponges, and bryozoans on a sand bottom (Ref. 34188).

Estimates based on models
Preferred temperature (Ref. 115969
): 23.5 - 27.6, mean 27 °C (based on 161 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00415 - 0.01826), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
