(total): 6 - 7;
soft rays: 12. Characterized by white body color with numerous red-edged orange spots on head and body; head and anterior body with three narrow reddish bars; two additional, less distinct bars below second dorsal fin; separate pelvic fins, joined by low membrane at base on fins; scaled midline of nape, scales on side of nape extending forward to above operculum; longitudinal scale series 66-71; greatest depth of body 5.0-5.6 in SL; more or less pointed caudal fin, usually longer than head (Ref. 90102).
Found in outer reef slopes, inhabiting burrows made by alpheid prawns in sand and rubble (Ref. 26237). Also found in sand-rubble bottoms adjacent to seaward reefs in 30-45 m (Ref 90102).
