Grows to about 30mm long. mantle pattern is essentially black with fine opaque white longitudinal lines, and a broad orange or yellow border. Characteristically there is a black line adjacent to the inner edge of the orange border. This enables the species to be readily distinguishable from the similarly coloured Chromodoris striatella in which there is a white line adjacent to the inner edge of the orange border. I have found it feeding on sponges of the genera Dysidea and Spongia.
