Annuloplatidia richeri sp. nov.

( Fig. 10 ; for a full systematic description see below)

This is the first record of the genus Annuloplatidia from the New Caledonian region including the Norfolk Ridge, although the genus is known from the western Pacific ( Zezina 1981b), Atlantic and eastern Pacific ( Atkins 1959; Bernard 1972; Lüter 2007). Annuloplatidia richeri was found only in sediment samples collected during Norfolk 1 cruise on 3 seamount cruises ( Tables 1, 2). Its bathymetric range is 200–967 m ( Fig. 14 ).
