Dear Daco,
Thanks very much for the photo. In general shape, Bosellia looks quite like Elysiella pusilla which also feeds on species of Halimeda. They both have a very flattened body, probably as a form of camouflage. The late Eveline Marcus told me she considered Bosellia to be her favourite genus. I suspect this was because Bosellia looks quite like the outline of a cat, with which she often used to decorate her letters. She was very disappointed that I could never send her species of Bosellia from the Indo-West Pacific, but apart from unverified reports from South Africa and the Red Sea, I don't think any species of Bosellia has been found outside the Atlantic.

Best wishes,
Bill Rudman.
