Similar in shape to Glossodoris atromarginata, with a high muscular body and narrow mantle skirt which is reduced on each each side to a sinuous ridge. It is bright white, except for a brown median dorsal band on the mantle running from in front of the rhinophores to just behind the gills. The band varies in width, widening to include the rhinophores, anteriorly, and the gills, posteriorly. The rhinphores stalk is white and the club is dark brown to black with a white line up the anterior and posterior midlines. The simple gills are translucent brown in colour. The mantle edge appears translucent greyish, apparently through the absence of opaque white pigment right at the edge of the mantle.

There is a single submarginal row of large discrete mantle glands, as found in G. atromarginata and other member of the Glossodoris atromarginata colour Group. The radular teeth are also similar in shape to those of G. atromarginata.
