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.

More Info


Offshore reefs of north Western Australia, Ashmore and Cartier Reefs in the Timor Sea, and the Great Barrier Reef and reefs in the Coral Sea, Queensland, to the Solitary Islands, New South Wales, with juveniles south to Montague Island; also Christmas Island in the eastern Indian Ocean. Elsewhere the species occurs in the tropical, east-Indo-west-central 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





Feeds mostly on benthic molluscs and crustaceans.





Juveniles regularly remove parasites from other fishes.

Similar Species


The species name dictynna, is from the Latin, Dictynna, another name for Diana “the goddess of the chase and the moon”, in recognition of the extreme similarity and close relationship between this species and Bodianus diana.
