   Description

   This nudibranch has a blue-white dorsum with four longitudinal black lines interspersed with raised ridges. It is a small Phyllidiid, growing to about 20 mm in length. There are sometimes black spots in the region between the outer black lines and the edge of the mantle. The rhinophores are lemon coloured or white. It is similar to Phyllidiopsis annae except for the colour of the rhinophores, which are black in that species. Phyllidiopsis phiphiensis is also similar but has three instead of four longitudinal black lines on the mantle.

   Diet

   This species feeds on a sponge.
