I have doubts about this yellow Berthella I found in the Etang de Thau (april 2004). Could it be Berthellina citrina? What is the difference between Berthella and Berthellina?

I am afraid this could be one of a number of yellowish pleurobranchs known from Europe. There is quite a correspondence on the Forum about this [see Lucas Cervera's message #8145 for an idea of the problem]. The only simple difference is the size of the fragile internal shell - large in Berthella, small in Berthellina - but that is not obvious in photos or live animals. So unfortunately in this case I have to admit total defeat
