A very small juvenile. The mid-dorsal longitudinal line is usually unbroken in this species.

This chromodorid nudibranch is characterised by the dark blue mantle with a single, narrow, mid-dorsal white stripe from between the rhinophores to the gill pocket and also by a similarly-narrow white submarginal white band. There are no additional markings on the mantle. There is a narrow white stripe under the mantle where it meets the foot. The gills and rhinophores are uniformly blue.
