Dear Yves,
This is most probably a species which I have identified as Glossodoris sibogae, but it is very similar to G. atromarginata so the only sure way to identify it is to look at its radular teeth! However from the general shape of the body, the bright yellowish background colour, and the broad white mantle border are all good signs that it is G. sibogae. It seems quite common in French Polynesiaa swe already have a record on the Forum from there, and Pruvot-Fol described it from the Tuamotu Archipelago as G. undulata.

Best wishes,
