In the Australian EEZ, recorded from Hibernia Reef, Timor Sea, and the far northern Great Barrier Reef, Queensland; also at Cocos (Keeling) Islands and Christmas Island in the eastern Indian Ocean. Elsewhere the species occurs in the tropical, Indo-west Pacific. Inhabits mixed sandy & rubble areas near reefs at depths to 30 m.

Features

Dorsal fin VI + I, 9; Anal fin I, 8; Pectoral fin 17-19; Longitudinal scale series 24-25; Vertebrae 26. 
Body depth 4.4-4.8 in SL; snout short, 3.4-3.7 in SL; posterior nostril near edge of orbit; sensory canals and pores present on head (2 lateral pores above preopercle); reduced sensory-papillae rows on cheek. Head naked except for scales on side of nape reaching nearly to orbit. 
First dorsal fin not higher than second (longest soft dorsal-fin ray longer than longest dorsal-fin spine); second or third dorsal-fin spine longest, 5.35-5.8 in SL. Pelvic fins disc-like, fully united medially by membrane; pelvic frenum present. 

Colour

Body translucent with numerous small dusky orange-yellow spots on head and body, those on head in oblique rows; a round black spot as large or larger than pupil in humeral region just above base of pectoral fin, and a second black spot of about the same size at mid base of caudal fin.
