Diagnosis: Dorsal rays VI-I, 13; anal rays 1, 13; pectoral rays 19-20 (usually 19); pelvic fins joined by a short membrane at base, with no frenum; fifth pelvic ray longest, branched once, the branches not separated. Longitudinal scale series 80-89; no median predorsal or prepectoral scales; scales on side of nape extending to above middle of opercle. Gill opening extending forward to below middle of preopercle. Body depth 5.55-6.15 in SL; head length (HL) 3.25-3.45 in SL; caudal fin rounded and moderately long, 2.8-3.1 in SL. Pale yellow dorsally, white ventrally, densely spotted with small pale blue spots; three broad dusky red bars on body, and a narrower darker one from nape across opercle and throat, broadly bordered by yellow containing small blue spots; a faint brown bar across posterior caudal peduncle, merging with brownish red of caudal fin base; second dorsal and anal fins with a broad longitudinal dusky band, the second dorsal yellow at base with dark-edged blue markings, the anal white at base with a broad yellow margin containing dark-edged blue markings; caudal fin with a large blue-edged elliptical mark that varies in zones from brownish orange to orange red, yellow, and black (Ref. 57552).
Inhabits sandy areas, near reefs, and lives symbiotically in a burrow with an alpheid shrimp (Ref. 57552).
