Septicollarina zezinae sp. nov.

( Fig. 8 ; for a full systematic description see below)

This is the first record of the genus Septicollarina from the New Caledonian region, including the Norfolk Ridge. The species was found on Jumeau East, Porthos and Zorro seamounts at a depth range of 670– 950 m. It occurs in the Fiji area (Bitner 2008) but, because of very limited material (one specimen), was at the time ascribed only to genus level. Two other species of Septicollarina ― S. hemiechinata Zezina, 1981a from off Java and S. oceanica Zezina, 1990 from the Eastern Pacific ― are known from shallower water (240–485 m).
