Hi Jerome,
Did you try to use the key for Nephtyidae in the book "Fauna Iberica,
Annelida Polychaeta I"? Maybe that could help. The full reference is:
Viéitez, J.M., Alos, C., Parapar, J., Besteiro, C., Moreira, J., Núñez,
J., Laborda, A.J., San Martín, G. (2004) Annelida, Polychaeta I. In:
Ramos, M.A. i sur. (Eds.) Fauna Ibérica, vol. 25. Museo Nacional de
Ciencias Naturales, CSIC, Madrid: 1- 530.
Good luck,
Barbara
