Chromodoris cavae from Reunion Island?

Concerning message #19782:
Dear Bill,
I found this chromodorid three weeks ago. It seemed to be a tropical western Pacific species. In the "Risbecia tryoni colour group" of Reunion Island we often saw Chromodoris geminus and Chromodoris cf geminus. Is it a Risbecia tryoni with pale blue rhinophore? or other species?
Locality: Rocky Coast Etang-Salé, 1 metre, Reunion Island, Indian Ocean, 5 April 2007. Length: 40 mm. Photographer: Hugues Flodrops.
Thanks for your help to identification.
Best regards.
Hugues.

Flodrops,H., 2007 (May 3) Chromodoris cavae from Reunion Island?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/19851Dear Hugues,
This is another one which should be considered part of the "Risbecia tryoni group" of similarly coloured species. From the relatively low profile of the body I am pretty sure it is not R. tryoni but a species of Chromodoris, and the most likely species is Chromodoris cavae. There are a number of species which have been described from the Indian Ocean - C. cavae, C.vicina and C. tennentana - which are still a bit confusing. Hopefully as we get more information - and photos like yours, we will b able to work out just how any species there are in this group.
You mention finding Chromodoris cf geminus at Reunion Is. I would like to see some photos of it from there.
Best wishes,
Bill Rudman
