Dear Bill and Paul,
Concerning Paul's aeolid from West Africa, I would recommend you check carefully the following reference:
• Ortea, J. & Espinosa, J. 1998. Estudio de nueve especies del genero Flabellina Voigt, 1834 (Mollusca, Nudibranchia) colectadas en Angola, Cabo Verde, Costa Rica, Cuba y Portugal, con la descripcion de tres especies nuevas. Avicennia, 8/9: 135-148.

In this paper, Flabellina marcusorum is redescribed from Costa Rica, including a photo. However, in the same paper, a new species of Flabellina, F. arveloi, is described from Cape Verde Archipelago, which resembles (a photo is also included) Paul's animal much more than F. marcusorum. Nevertheless, details of the internal anatomy would help to confirm the ID.

Thanks Lucas,
I have a major problem with papers published in Avicennia as no library in Australia subscribes to it. Fortunately I have just received a message from Gonçalo Calado, with photos of F. arveloi, but I have no information on its anatomy. It is most likely Paul's animal is the same as F. arveloi. I guess what has to be investigated is whether F. arveloi and F. marcusorum are distinct. Ortea & Espinosa, 1998 may present convincing evidence in their Avicennia paper, but I have been unable to obtain a copy.
Best wishes,
Bill Rudman
