Prionospio cirrobranchiata Polychaetes of Greece: an updated and annotated checklist Faulwetter, Sarah Simboura, Nomiki Katsiaras, Nikolaos Chatzigeorgiou, Giorgos Arvanitidis, Christos Biodiversity Data Journal 2017 5 20997 20997 67KS8 Day, 1961 Day 1961 Polychaeta Spionidae Aonidella CoL Animalia Aonidella cirrobranchiata Spionida 0 20997 Annelida species cirrobranchiata   Prionospio cirrobranchiataDay, 1961  Notes Questionable status. In the Mediterranean only reported from Greece ( Bogdanos and Satsmadjis 1983). Commonly distributed in West Atlantic and South-West Africa. Arvanitidis (1994)regards its presence in the Mediterranean as doubtful. Day (1961)and Day (1967)include it in the subgroup of Prionospiospecies with apinnate branchiae. Maciolek in her unpublished dissertation ( Maciolek Blake 1983) and Lopez-Jamar (1989)moved it to a new genus ( Aonidella) on the basis of other unique diagnostic characters (for more information see Maciolek 2000). Re-examination of the material would be required to investigate the possible assignment of the Greek record to a Prionospio (Minuspio)species with apinnate branchiae.
