After receiving Nishina Masayoshi's message on Eubranchus misakiensis it seems the animal from Hong Kong in Bernard Picton's photos is not that species. E. misakiensis has far fewer brown spots, and lacks the yellow and blue colour markings. The only species I can find with a similar colour pattern is Malcolm Edmunds' Eubranchus rubropunctatus, which was described from a single specimen from East Africa. The Hong Kong animal lacks the red spots in the subapical blue band on the cerata of the type specimen but until further material is available we will be unable to say whether they fit within the colour range of a single species.
