Distribution / Remarks. The photographs on the La Reunion website show mating, egg laying, and egg development during the breeding season, November. This common Indo-West Pacific species known as Philinopsis cyanea, with an extremely variable colour pattern, has an older name, Philinopsis speciosa, which was previously considered as endemic to Hawaii. Rudman (http: // www. seaslugforum. net / find / philspec) states that there are no anatomical differences between the two, and Gosliner et al. (2008) have combined them under the older name with no discussion or comment. Pease (1860) described the habit of stressed slugs vomiting perfect shells of Bulla, as recorded for specimens from the Red Sea (Yonow 1992) and Zanzibar (Rudman, Sea Slug Forum). Philinopsis cyanea is formally synonymised with Philinopsis speciosa in this work.
