Phyllidiopsis gemmata? from Mauritius

December 18, 2006
From: Hugues Flodrops

Dear Bill,
Here are two others specimens of Phyllidiopsis gemmata found under the same rock in Mauritius. The characteristics are similar to P. gemmata from Reunion,  also with transverse black rays around the mantle edge [see message #19024 ].

Locality: Ilot Tamarin, Flic and Flac, 16 metres, Mauritius, Indian Ocean, 20 November 2006. Length: First 40 mm, Second 35 mm. Photographer: Hugues Flodrops.

All the specimen from "Mascareignes" seems to have these rays. Another species has three median longitudinal ridges and black spot around, it's Phyllidiopsis striata. But P. striata have usually lemon yellow rhinophore.
We think that this is a new characteristic for the species.
Thanks for your comments and for your forum.
Best regards.
Sandrine and Hugues Flodrops

Thanks Sandrine & Hugues,

It certainly seems to have a distinctive colour pattern. I have looked at the various publications of Brunckhorst, Yonow and Schroedl and can find nothing similar, so as I said in your earlier message, I'll leave it as P. gemmatafor the time being.

Best wishes,
Bill Rudman
