The single specimen of this species so far found was on 21 September 2008 under an old concrete slab dumped as shoreline reinforcement along the middle of the lagoonside of Kwajalein Island. Depth was about 1m. The animal measured 12mm in length, and it was nestled on the rock among three white spiral egg masses. Although it doesn't exactly match Hallaxa paulinae, particularly in the lack of a subapical black spot on the rhinophores and the presence of scattered small white specks, we think it is pretty close in other characteristics. Internal anatomy would need to be examined for confirmation.
