See message #16239 suggesting it is F. affinis

Concerning message #16148:

Dear Marina and Bill,
I think that the specimen photographed by Marina could be Flabellina ischitana.

F. ischitana and F. affinis are sympatric species in southern Iberian Peninsula and you can find together on the same hydroid. On the other hand, in my knowledge with specimens of such area, the egg masses of both species are different in color, white and pink respectively.

I have no data about the possibility of a color change from white to pink for the F. ischitana 's egg masses. Maybe Marina has found specimens of F. ischitana close to a F. affinis' egg mass.

Marina, did you see the specimen of "F. ischitana" laying a pink egg mass? If you did, maybe your animal is F. affinis, with a very tiny deep violet surrounding area under the opaque white subapical ceratal area.

Sorry...
Regards.
Lucas.
