Nautiliniellid polychaetes collected from the Hatsushima cold-seep site in Sagami Bay with descriptions of new genera and species
Polychaete species belonging to the family Nautiliniellidae were found in the mantle cavities of two bivalve species collected from the Hatsushima cold-seep site in Sagami Bay at a depth of 1170 m. As a result of the comparison with Nautiliniella calyptogenicola, new combination, two new genera and two new species are described. The new genus Shinkai differs from the type genus of the family in having only one pair of prostomial antennae instead of two pairs. Shinkai sagamiensis new species is parasitic on Calyptogena soyoae. Natsushima bifurcata, new genus and species, differs from all other species of the family by the presence of additional numerous bifurcate setae on each parapodium instead of the exclusive presence of simple hooks in tile others. This species is parasitic in the mantle cavity of an undescribed bivalve species of the genus Solemya. The position of the family Nautiliniellidae is discussed, after a reexamination of the type specimens of Antonbruunia viridis.
