The animal has a flattened elongate oval shape with a wide mantle margin overhanging the head and foot. The mantle is heavily spiculate, and has a well developed median posterior notch in which are found the gills and anal papilla. The background colour of the animal is translucent white, covered with dense chocolate brown spots, except at the anterior and posterior ends. The rhinophores are pale yellow and the gills are white. At the base of the two outer gills are shiny white, paired branchial glands. The ventral surface is unpigmented. The largest specimen in the original description was 6.5mm long.
