Phyllidiopsis gemmata? from Reunion Is

December 18, 2006
From: Hugues Flodrops

Dear Bill,
Here are two specimens of Phyllidiopsis gemmata (Pruvot-Fol,1957) caracterised by three tuberculate rides and four narrow black lines. In Reunion Island and in Mauritius (next message), we can observe transverse black rays arund the mantle edge in the four specimens found.

Locality: Upper photos: Saint-Leu, 15 metres, Reunion Island, Indian Ocean, 1 december 2006. Length: 35 mm. Photographer: Hugues Flodrops. Lower photo: St-Gilles "Canyon" Indian Ocean Depth 14 metres, specimen lenght about 30 mm. Date observed: 28 november 2006. Photographer: Hugues Flodrops.

Thanks for your comments.
Best regards.

Dear Sandrine & Hugues,

Thanks for these interesting photos. In many ways this looks like a species of Phyllidiella but I know of none that looks like this. The transverse black lines are unusual, in fact I can find no record of them being observed before, so there si a chance it is a different species. However in all other features it appears to be P. gemmata so I think at this stage we will leave it there.
Best wishes,
Bill Rudman
