This sand dwelling aeolid has a wide tropical Indo-West Pacific distribution with published records from New Guinea (Quoy & Gaimard) and Tahiti (Bergh). I have found it in Zanzibar, Tanzania and New Caledonia. It is characterised by the relatively long cerata, white body and cerata, and yellow (upper) and black (lower) band near the ceratal tip.
