Spionidae (Annelida: Polychaeta) from the Galápagos Rift Geothermal Vents
Proceedings of the Biological Society of Washington
Three new species of spionid polychaetes have been collected from biological communities associated with geothermal vents along the Galápagos Rift. Each species belongs to a separate genus, 2 of which are new. Xandaros acanthodes, new genus and species, has branchial and neurosetal features unique to the family. A new genus, Laubieriellus, is erected for L. grasslei, new species, and Prionospio salzi Laubier, 1970. A new species, Prionospio {Minuspio) sandersi, is also described from vent communities. Samples taken as part of a study of the infaunal diversity in sediments near vent areas contained Aurospio dibranchiata Maciolek, 1981, recently described from several Atlantic locations. This is the first Pacific record for A. dibranchiata.
