Presently the Family Fionidae includes Eubranchus, Abronica, Tergipossa, Fiona and Tenellia. Nudibranch and Sea Slug Identification presents 83 undescribed species of Tenellia. Jim's critter here makes 84. While is has similar coloration to several Tenellia and Abronica species, it seems distinct. The smooth rhinophores and head tentacles are opaque white. The body is covered with large white spots. The cerata have a purplish tip (cnidosac) followed by a dark red band, followed by a wide orange band, and a wide white band midway down. The base of the cerata is light orange. While wild ceratal bands like these are not uncommon in this family, but none that I am aware of match this arrangement.
Those of you diving the Lembeh region, let's keep our eyes open for this beauty, so we can learn more about it!

Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
