The very characteristically coloured elysiid is known from both the east and west coasts of Australia (Wells & Bryce, 1993; personal observations). I have found it in New Caledonia, and Gosliner has recorded it from other parts of the western Pacific. It is characterised by the clusters of deep green marks on a dull cream background. The rhinophores are cream except for green patterning at the base and a brownish orange tip.
