This is a 22mm individual found at Enewetak Atoll, under dead coral at a depth of 6 meters on a southeastern lagoon pinnacle. We have also seen at least three specimens on lagoon reefs at Kwajalein Atoll, and John and Lynette Flynn report additional specimens from Rongelap Atoll.
The specimen in the two photos below were found on a Kwajalein Atoll lagoon pinnacle on 26 June 2010. It looks intermediate with specimens we are tentatively calling Discodoris ylva, so it is possible that all ours are D. coerulescens.
