A new species of Perinereis (Polychaeta, Nereididae) from Florida, USA, with a key to all Perinereis from the American continent by De León, Jesús, Goethel, Carrie

“…The genus Perinereis includes more than 70 species, of which, P. aibuhitensis (Grube, 1878), P. brevicirrata (Treadwell, 1920), P. camiguinoides (Augener, 1922), P. jascooki Gibbs, 1972, P. kuwaitensis Mohammad, 1970, P. singaporiensis (Grube, 1878), P. vancaurica (Ehlers, 1868) and the new species have two short bars on Area VI and notopodial dorsal ligules that are not greatly expanded. The most geographically close species is P. brevicirrata. The new species can be distinguished from P. brevicirrata by the absence of a notopodial prechaetal lobe, Area V with 3 cones in a triangle, and Area VII-VIII with two well-defined rows of 33 paragnaths, the basal row having longer paragnaths in relation to the distal ones. …”
