N2 - Though most common in coastal sandy bottoms, nerillid annelids have been found in a broad variety of habitatsaround the world and two genera have previously been reported from the deep sea. During a cruise to the southernEast Pacific Rise and northern Pacific Antarctic Ridge (near Easter Island) in 2005, six specimens of a new speciesof Mesonerilla were collected at depths of 2234-2649 m. Samples were taken via DSV Alvin with a slurp guncollecting fine silt and volcanic glass shards in cracks, fissures, and mussel beds from 5-20 m away from activeventing areas. As well as being the first deep-sea hydrothermal vent associated nerillid, this is the first record of anadult meiofaunal annelid from deep-sea hydrothermal vent areas and the first record of Mesonerilla from the deepsea. Based on the new material we here describe a new species of Mesonerilla, M. neridae sp. nov., with ninechaetigerous segments, three antennae, long chaetae, and almost no ciliation. It resembles the subtidal, interstitialM. roscovita in the shared presence of a short median antenna and M. fagei and M. lüderitzi by presence of chaetaein the shared presence of a short median antenna and and by presence of chaetae in segment one and relatively short parapodial cirri.
