Three new species of Syllis (Syllidae : Polychaeta) from Iberian coasts.

During the project "Fauna Iberica", established to develop a complete study of the Iberian fauna, several new polychaete species belonging to the fami ly Syllidae were found and we describe here three new species included in t he genus Syllis. Syllis parapari sp. nov. is characterized by the presence of both pseudospiniger and falciger compound chaetae, short and spindle-sha ped dorsal cirri on midbody parapodia and posterior aciculae with an obliqu e tip and a subdistal knob. S. pontxioi sp, nov, is characterized by very s hort antennae, tentacular and dorsal cirri; by the shape of midbody and pos terior chaetal blades, very short and with an enlarged distal tooth; by sto ut posterior aciculae, with a slightly curved tip. S. jorgei sp. nov. is ch aracterized by very long spines on the cutting edge of falciger blades, the distal ones longer than the terminal tooth, by the shape of aciculae with subdistal knobs and acute tips. These three species have been previously re ported for the Iberian fauna as Syllis cornuta, S. gerlachi, and S. lutea. However, after comparison with a recent re-description of these species, th e authors conclude that the species studied here are three new species.
