soft rays: 10. Characterized by pale grey body color with numerous small white dots and larger brown spots on head and body; row of four large ovate blotches along side at level of pectoral fin base; base of caudal fin with additional spot; united pelvic fins, well developed frenum present; rounded caudal fin, slightly shorter than HL; longitudinal scale series 28-29; ctenoid scales on body and nape; cycloid scales on prepectoral area, breast, cheek and opercle; predorsal scales about 12; 1-2 small spines on preopercular margin just above angle; depth of body 4.2-4.7 in SL (Ref. 90102).
