摘要
Alvinellid and nautiliniellid polychaetes from the deep-sea hydrothermal vents, the Izena Hole and the Iheya Ridge of the middle Okinawa Trough, were studied taxonomically. Paralvinella hessleri was newly recorded from the Izena Hole, about 2000 km apart from its type locality of the Mariana Back-Ark Basin. Another species was found in the mantle cavity of an unidentified species of the genus Calyptogena from the Iheya Ridge. This nautiliniellid polychaete is very close to Shinkai sagamiensis, however it differs from the latter in having very long notopodia instead of short ones. The description of this new species, Shinkai longipedata, was given.
