Summary:
Very similar to and easily confused with Bodianus diana, a species found only in the Indian Ocean.

Juveniles are brown with few white spots on the head above the level of the mouth, and no spots on the snout; the white spots on top of the head are sparse and usually large, and those below and behind the eye often join to form irregular stripes. 

Males (terminal phase adults) have a large prominent black spot on the rear of the dorsal fin, and on the middle of the anal and pelvic fins.

Distribution

Found in the tropical western Pacific from the eastern coasts of the Indo-Malaysian Archipelago to Japan, Palau, western Micronesia, Samoa, Tonga and southeastern Australia. It is excluded from the Indian Ocean, except for offshore islands of northwestern Western Australia and the southern coasts of eastern Indonesia, west to about Java.

Individuals inhabit coral reefs, mostly at depths of  9–30 m. Juveniles often shelter in caves or near gorgonians and black corals, and also among the tentacles of the free-living mushroom coral Heliofungia actiniformis
