Upper: CASIZ 140334, Tulamben, Bali, Indonesia, 7 mm. Photo: T. Gosliner. Lower: CASIZ 140334. Radular morphology. Scale =10 µm. [From Gosliner & Fahey 2008: Fig. 22C].

The background colour of the body is white but most of that is obscured by a dull orange-yellow pigment which covers most of the dorsum except for areas where elongate grey-black patches are clustered to form a symmetrical pattern. Anteriorly, these black marks form a band around the edge of the head and cover the bottom half of the oral tentacles. Between the rhinophores and the gills they form a Y shaped pattern which expands just in front of the gills to encircle the gills and then forms a median band behind the gills. The dorso-lateral processes are white with an orange-yellow streak along the dorsal surface. The rhinophores and gills are transparent with opaque yellowish markings.

There are raised rounded tubercles of irregular size on the dorsum, most of which are found just in front, or just behind the gills. The living animals grow to at least 7 mm in length.
