Hi Bill,
a Happy New Year to you!
At Wolfgang Seifarth's site is a photo labelled Reticulidia sp. from the Maldives, Ellaidhoo Island, which looks exactly like my Phyllidia sp. 1. Wolfgang says the ID Reticulidia sp. was made a long time ago by Bill what is it?
I attach a smaller version of the photo.

Dear Erwin,
I don't remember identifying the animal as Reticulidia for Wolfgang but I must have based my guess on the ridges on its back. Identifying unknowns from photographs is a very perilous occupation. Without specimens there is no way to be sure, but my feeling now is that it is not Reticulidia but probably closely related to Phyllidia polkadotsa, which is also yellow with back markings and has an identical ridge down each side of the mantle.

Best wishes,
Bill Rudman.
