Characters
Teeth are small and arranged in narrow bands in jaws, palatine, and vomer. Preorbital bone has two spinous points over maxilla, with first rounded and second broadly pointed. Suborbital ridge has five to eight spinous points. Nasal, preocular, supraocular, postocular, frontal, anterior and posterior parietal, postorbital, pterotic, lower posttemporal, supracleithral, cleithral, suborbital, and preopercular spines are present. Preoperculum has 5 spines, with first the longest and bearing supplemental spine, and third, fourth, and fifth well developed. Measurements are expressed as percent of SL: head length 46%–48%, snout length 12%–14%, orbit diameter 13%–14%, interorbital width 4%–6%, jaw length 22%–23%, body depth 35%–40%. Gill rakers on first arch number 5 or 6 on upper limb and 14 or 15 on lower limb. Slit behind fourth gill arch is very small. Pectoral fin rays number 16 or 17, with upper 1 or 2 unbranched, adjacent 3 to 6 branched, and remaining unbranched. Dorsal fin has 12 spines and nine rays. Anal fin has 3 spines and five rays. Scales on body are ctenoid. Lateral line consists of several tubed scales behind head. Vertebrae number 25, and gas bladder is present.
Pinkish red, with saddle-shaped patches of dark pigment at dorsal fin origin, below center of spinous section of dorsal fin, between dorsal insertion and anal fin, and at base of caudal fin. Dark patch is present between fifth and ninth dorsal fin spines.
