Here are two images of what I think is Costasiella kuroshimae. There are bright blue spots on the cerata ... and one has orange rings. Their tips of cerata are translucent ... which differ from Ichikawa's original description.
They are 3.5 mm long, on the rope of a fish preserve in Kerama Is. Okinawa.

Thanks for these photos. They are much closer to Ichikawa's description of C. kuroskimae than Erwin Koehler's photos. The differences in your two photos well illustrate the problems of describing species from very few animals. Clearly some animals of this species have a yellow-orange ring on the cerata.
