Polycera quadrilineata or P. aurantiomarginata?

June 18, 2002
From: J-P. Bielecki

Hi Bill
Here is a photo of what I supposed to be Polycera quadrilineata with the two color variation and crawling together. But after seen the Polycera aurantiomarginata species from Baki Yokes, I am not sure about my first ID. Could you please give the keys characteristics to distinguish these two species.

Species seen in April 2000, Dive site: Sète, étang de Thau, [Mediterranean coast, France] Size: 2cm, Depth:6m.
Regards,
Jean-Pierre

Dear Jean-Pierre,
Thanks for the photo. I too am puzzled with these two species. I have asked Lucas Cervera for guidance
