soft rays: 9;
Vertebrae: 27. Body red with a very narrow darker red stripe separating longitudinal scale rows; spinous part of dorsal fin red; mottled faintly with white, the outer part of each membrane deeper red; remaining fins with red rays and clear membranes. 4-5 oblique rows of scales on cheek. Body depth 2.3-2.6 in SL; head length 2.5-2.6 in SL. Rounded anterior end of nasal bone; moderately large and spineless nasal fossa; surface of nasal bone between fossa and edge of premaxillary groove with a prominent retrorse spine; median edge of nasal bone (margin of premaxillary groove) with a small recumbent retrorse spine; longest dorsal spine 2.05-2.75 in head length; third anal spine 1.5-1.6 in head length; broadly rounded caudal fin lobes (Ref. 27370). Strongly serrated scales (Ref. 37816).

Estimates based on models
Preferred temperature (Ref. 123201
): 24.7 - 29, mean 27.1 °C (based on 617 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00756 - 0.03322), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.6 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.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
