	abstract = {Darwin {\{}[{\}}1] hypothesized that sexes in a species should be similar unless sexual selection, fecundity selection, or resource partitioning has driven them apart. Male dwarfism has evolved multiple times in a range of animals, raising questions about factors that drive such extreme size dimorphism {\{}[{\}}2-4]. Ghiselin {\{}[{\}}5] noted that dwarf males are more common among smaller marine animals, and especially among sedentary and sessile species living at low densities, where mates are difficult to find, or in deep-sea environments with limited energy sources. These benefits of male dwarfism apply well to Osedax (Annelida: Siboglinidae), bone-eating marine worms {\{}[{\}}6]. Osedax males, notable for extreme sexual size dimorphism (SSD), are developmentally arrested larvae that produce sperm from yolk reserves. Harems of dwarf males reside in the lumen of the tube surrounding a female. Herein, we describe Osedax priapus n. sp., a species that deviates remarkably by producing males that anchor into, and feed on, bone via symbiont-containing {\textquoteleft}{\textquoteleft}roots,{\{}{\textquoteright}{\textquoteright}{\}} just like female Osedax. Phylogenetic analyses revealed O. priapus n. sp. as a derived species, and the absence of dwarf males represents a character reversal for this genus. Some dwarf male features are retained due to functional and morphological constraints. Since O. priapus n. sp. males are anchored in bone, they possess an extensible trunk that allows them to roam across the bone to contact and inseminate females. Evolutionary and ecological implications of a loss of male dwarfism are discussed.},

	abstract = {Four genera and five species of Nautiliniellidae (Phyllodocida; Annelida), representing four new species and one new record, were found in association with bivalves belonging to Mytilidae (Bathymodiolus spp.), Solemyidae (Acharax sp.) and Vesicomyidae (Calyptogena and Vesicomya) from hydrothermal vents of the western Pacific (Lau back-arc basin) and cold seeps of the eastern Pacific (Costa Rica). Iheyomytilidicola lauensis n. sp. is characterized by the presence of unidentate hooks; Laubierus alvini n. sp. has long dorsal cirri and notoacicula not protruding in any segment; Natsushima sashai n. sp has bifurcate chaetae with distal teeth markedly different in length and width between each other; and Shinkai fontefridae n. sp. differs in having posterior hooks with subdistal spines. Sexual dimorphism is described for Shinkai and Natsushima species and confirmed by DNA sequencing (Cytochrome c oxidase subunit I sequences). In addition, one specimen of N. bifurcata Miura {\&} Laubier, 1990 from the Gulf of Cadiz has been studied to compare it morphologically and genetically with N. sashai n. sp. Scanning electron and optical microscopy images are provided for each species, as well as pictures of live animals. Morphological features described and documented for the first time include the presence of internal longitudinal chambers within chaetae and possible evidence that the simple chaetae, characteristic of nautiliniellids, may be derived from compound chaetae.},
