Philinopsis speciosa

Distribution. Widespread across the Indo-Pacific including Mozambique (Tibirica and Malaquias 2016), Maldives (Yonow 1994), Vietnam (Martynov and Korshunova 2012), Australia (Nimbs and Smith 2016), Guam, Hawaii, the Galapagos Islands (Zamora-Silva and Malaquias 2018), South Africa, Tanzania, the Philippines, Indonesia, Papua New Guinea, Japan, Panama (Gosliner et al. 2008), and Red Sea (Yonow 1990). Previously documented from Thai waters (Nabhitabhata 2009) but a specific location was not given. Here confirmed from the Gulf waters of Thailand.

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.
