Two new species of <i>Cirrophorus</i> (Polychaeta: Paraonidae) from the northern Gulf Of Mexico
Proceedings of the Biological Society of Washington
Two new species of paraonid polychaetes, Cirrophorus perdidoensis and C. perkinsi, are described from coastal waters off Perdido Key, Florida. The two species co-occur in moderately coarse sand substrate at depths from 1.6 to 7.0 m. Cirrophorus perdidoensis has slender, lyrate forked notosetae that are slightly asymmetrical; C. perkinsi has stout, acicular forked notosetae that are bayonet-shaped. The two new species and C. juvenalis (Hartmann-Schröder) are distinguished from other members of the genus by their small size, less than 4 mm, four or fewer pairs of branchiae, and by having two or more posterior segments reduced and represented only by dorsal podial lobes.
