It is a marine gastropod mollusc in the family Dendrodorididae.

This species has so far only been found around the southern African coast off the Atlantic side of the Cape Peninsula in 10–30 m. It is probably endemic.

[1] The white-spotted nudibranch has a translucent white- to tan-coloured body, which may have a bluish tinge.

The body is covered with white protuberances.

The perfoliate rhinophores are cream-coloured as is the gill rosette.
