This species has recently been described from the Ryukyu Islands in southern Japan. The mantle is translucent white with many large white patches, and the head tentacles [rhinophores] are tipped with orange. There is an orange band around the posterior `spout', and there can be an orange band at the anterior end of the mantle. Specimens from New Caledonia are very similar in colour, but lack the anterior orange band. It is apparently a  small species, largest animal with a 5 mm long shell.
