Description
Dorsal spines (total): 7; Dorsal soft rays (total): 10-11; Anal spine: 1; Anal soft rays: 9-10 (usually: 9); Pectoral fin rays: 17-19; Longitudinal scale series: 21-24; Predorsal scales: 5, reaching to behind eyes; Transverse rows of scales backwards: 7; Ctenoid scales on body, becoming cycloid anterior to pelvic and pectoral fins. Depth of body: 3.7-4.0 in SL. Spines on rear edge of preopercle: 3-7, lowermost often larger than others; Rounded caudal fin; Pelvic fins united medially, disc-like; Fourth dorsal spine, forming long filament in adult. Cheek naked; Opercle with large ctenoid scales; Large spine on rear edge of preopercle, with 2-4 smaller spines above it. Max. length: 4.6 cm SL. Depth range: 1 - 30 m, usually: 3 - 15 m.
Color
Head and body translucent whitish, covered with pale orange blotches and small spots, several small dusky spots along midsides of body; Head with blackish vertical bar from eyes to just below corners of mouth; Blackish oblique blotch or streak behind eyes;A diffuse black spot (about size of pupil) usually present between first and second spines of first dorsal fin; Short dark vertical line at caudal fin base.

Asterropteryx: from Greek prefix, a- , an- = not, without, (having) no + from Greek, sterrhos, -a, -on = firm, solid + from Greek, pteryx = fin. Referring to slender and flexible dorsal fin spines.
spinosa: from Latin, spinosa = spiny. Referring to five bony, spine-like projections on preopercle.
