    Sinilar in colour to Glossodoris atromarginata it differs in having a much softer body and wider mantle skirt. The mantle glands are easily seen as an irregular opaque white band near the mantle edge. The mantle is bordered by a thin line which varies in colour from black and dark brown to a pale pinkish brown. The rhinophore stalj is translucent white and the club is black with a thin whitish line up the anterior midline. The simple gills are translucent white with a black dusting along the edges, especially in the upper half to one-third. In some animals the whole upper third of each gill is dusted with black. The gills move rhythmically. It grows up to 45mm long.
