Kristian Fauchald's Polychaeta DB

A new species of the genus Dentatisyllis Perkins, 1981 and another new species of the genus Branchiosyllis Ehlers, 1887 are described: Dentatisyllis morrocoyensis and Branchiosyllis lorenae. The specimens of both new species were collected during a study of the polychaetes from Thalassia testudinum beds in Morrocoy Park, Venezuela. One specimen of B. lorenae was previously collected and reported as Branchiosyllis sp., from Cuba by San Martín (1991), so this species could be distributed throughout the Caribbean area. Dentatisyllis morrocoyensis is distinguished from all other species of the genus by the high number and shape of teeth in the trepan and shape of the blades of the compound setae, unique in the genus. Branchiosyllis lorenae is very similar to B. exilis but differs by having, on the anterior and midbody parapodia, 1-2 compound setae, the bidentate blades of which are slightly curved and bear a distal tooth somewhat shorter than the proximal one. This latter characteristic is unique to the genus.
