PROC. BIOL. SOC. WASH. 97(3), 1984, pp. 555-582 NEW SPECIES OF PHYLLODOCIDAE AND HESIONIDAE (POLYCHAETA), PRINCIPALLY FROM FLORIDA Thomas H. Perkins Abstract.— The following new species are described: Eumida (Eumida) parvi-cirrus, Eumida (Pirakia) hutchinsonensis, Paranaitis gardineri, Heteropodarke lyonsi, H. formalis, Kefersteinia haploseta, and Podarkeopsis levifuscina. Kefer-steinia sp. is informally described. Oxydromus arenicolus glabrus Hartman, pre-viously referred to Oxydromus brevipalpa Hartmann-Schroder, is a distinct species which, with O. brevipalpa, Oxydromus capensis Day, and Gyptis maraunibinae Gibbs, are species of Podarkeopsis Laubier, and new combinations. This report is one of several (Perkins 1979, 1980, 1981, 1984) based primarily on collections made between September 1971 and July 1973 in an environmental baseline study of marine biota near the Florida Power and Light Company nuclear power plant at Hutchinson Island, St. Lucie County, Florida. Additional speci-mens collected later at Hutchinson Island and specimens from North Carolina and the eastern Gulf of Mexico are included. A species of Hesionidae, Microph-thalmus hartmanae, has been described previously from these collections (Westh-eide 1977), and another Microphthalmus species awaits description (Wilfried Westheide, in litt.). The study area and methods were described by Gallagher and Hollinger (1977). Sediments were described by Gallagher (1977). Other aspects of the physical and chemical environment were reported by Worth and Hollinger (1977). Brief de-scriptions of benthic sampling stations and methods were also given by Perkins (1979). Types and other material available for study are deposited in the Allan Hancock Foundation, University of Southern California (AHF); British Museum (Natural History) (BMNH); Invertebrate Reference Collection of the Florida Department of Natural Resources Bureau of Marine Research (FSBC I); Marine Environmental Sciences Consortium, Dauphin Island, Alabama (MESC); Mote Marine Labora-tory, Sarasota, Florida (MML); U.S. National Museum of Natural History, Smith-sonian Institution (USNM); Universitetets Zoologiske Museum, Copenhagen (ZMC); and Zoologisches Institut und Zoologisches Museum, Hamburg Univer-sity (ZMH). Dr. Marian H. Pettibone (USNM), Dr. Thomas Hopkins (MESC), and Mr. Jay Leverone (MML) loaned specimens. Mr. Robert G. Ernest, Applied Biology, Inc., Jensen Beach, Florida, and Mr. Harvey Rudolph, Florida Department of Envi-ronmental Regulation, donated specimens. Specimens of Kefersteinia sp. loaned by Mr. Leverone were collected and identified by personnel of Mote Marine Laboratory for the Bureau of Land Management, contract no. AA815-CTO-50. James F. Quinn, Jr., of the Bureau of Marine Research helped with the Latin names. Kristian Fauchald (USNM) provided a copy of a description not available
