TAXONOMY AND ECOLOGY OF ANNELIDA OF THE I BERIAN PENINSULA - POLYCHAETA FROM THE RIA-DE-FERROL

As a result of a wide project-guided to characterize the fauna and flo ra of the Ria de Ferrol (Galicia, NW Spain), we present in this work 1 2 species of polychaetous annelids from the intertidal area and sublit oral infaunal benthos of this ria. Phyllodoce longipes Kinberg, 1866 a nd Octobranchus lingulatus (Grube, 1866) are recorded for the first ti me in the littoral of the Iberian Peninsula. Harmothoe nigra Alaejos, 1905 tor the first time after its original description and Vermiliopsi s striaceps (Grube. 1862) for the first time in the atlantic coasts of Spain. The juvenile stages of Marphysa belli (Audouin & Milne-Edwards . 1833) and M. sanguinea (Montagu, 1815) often attributed to other eun icid species. are described. Finally, for six species with a scarce kn owledge in our waters, we make some precisions about their morphology and ecology : Phyllodoce groenlandica Oersted, 1843, Paranaitis koster iensis (Malmgren. 1867). Harmothoe antilopes McIntosh. 1876, H. ljungm ani (Malmgren, 1867), H. longisetis (Grube, 1863) and Gyptis capensis (Day. 1963).
