Re: Polycera aurantiomarginata? from Turkey

Hi Bill,
I'm not sure if this species is P. aurantiomarginata. I am not sure if there are some orange marks along the edge of the foot of the upper animal, but it's not clear. This feature give the specific ethymology. I have seen also some specimens of P. quadrilineata with a colour pattern quite similar to Baki's animals.

Dear Lucas,
Any help you can give will be welcome. I am afraid I am unable to quickly get hold of a copy of the original description of P. aurantiomarginata. Is a yellow line along the edge of the foot the only external character separating P. aurantiomarginata from the blue colour form of P. quadrilineata? I note that in Alma Sánchez's photo of Polycera aurantiomarginata there is dark blue on the rhinophore club and on the gills. What about the papillae on the anterior mantle veil. I see P. quadrilineata have 4 and Alma's specimen of P. aurantiomarginata has 6. Is this a good character?

It is puzzling that what seems to be a very similar animal is identified in Ocaña Martin et al, 2000 as P. quadrilineata.
Thanks,
Bill
