Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 10; Anale stekels: 1; Anale zachte stralen: 8 - 10. Body whitish with orange spots covering both body and head; a black spot at the base of dorsal-fin spines and another at base of caudal. Preopercle spines, 4-7. Well-developed basal membrane of pelvic fin, extending for most of length of innermost ray. Caudal fin rounded to lanceolate. Cycloid scales on head, cheek and opercle, also on pectoral base and prepelvic region; ctenoid scales on predorsal and the rest of the body (Ref. 31115).
Found in sand and rubble patches, located on ledges of steep seaward or lagoon reef slopes or at the base of these slopes. The fish lies on the bottom, retreating into crevices when threatened (Ref. 31115). Solitary (Ref 90102).
