چکیده

During the BIOACCESS Japanese cruises (1996 & 1998), active hydrothermalism and associated vent fauna were studied on the South-eastern Rift of Manus Basin (South-western Pacific). In the PACMANUS vent field, a conspicuous vent fauna was sampled, including an actinostolid sea anemone (Actiniaria) belonging to an undescribed genus and species. Pacmanactis hashimotoi gen. et spec. nov. is here described, and represents the 9th sea anemone reported from hydrothermal vents.
