External morphology. Living animals 12–18 mm in length. Body oval with three marginal bands on the mantle edge. Notum smooth with no apparent spots. Six to ten unipinnate gill branches. Eleven or twelve lamellae on rhinophores. The color pattern exhibits two distinct morphotypes. Morphotype A (Fig. 4a–c) has a creamy opaque white body. The outermost portion of the mantle edge is tinged an opaque bluish white, followed by a deep red band, followed by a yellow submarginal band, and then an opaque white band, with all bands having similar widths. Gill branches and rhinophores are reddish purple with white edges. Morphotype B (Fig. 4d) has an opaque creamy white body. The outermost portion of the mantle edge is surrounded by a speckled opaque white band, followed by a deep red band, a yellow submarginal band, and then an innermost opaque white band. The gill and rhinophores are reddish purple with white edges and opaque white speckles.
