First record of Scalibregma celticum (Annelida: Polychaeta: Scalibregmatidae) in Italian marine waters.

The polychaete Scalibregma celticum was recorded for the first time along the western Italian coast (Mediterranean Sea). A survey was carried out in February 2009 off the Sardinia north-east coast. Six individuals of S. celticum were collected at 40 m depth on a sandy substratum. In the present study they are described, pointing out the difference between S. celticum and S. inflatum a species more common along the Italian coast. [ABSTRACT FROM AUTHOR]
