Mantle translucent clear with a diffuse opaque white medial band down the mantle. At the mantle edge there is a diffuse creamy yellow submarginal band and a white marginal border. Along the edge is a thin golden yellow line (see inset on top photo). The gills and rhinophore clubs are edged with reddish brown. There is a wide line up the posterior midline of the rhinophores. The gills have a fast flickering movement when the animal is crawling. There are about 20 chromodorids with a white mantle and gold or yellow border which I have discussed previously as the Chromodoris aureomarginata colour-group. These colour groups are just a convenient way of comparing similarly coloured species and have no phylogenetic significance.
