Campages mariae (Adams, 1860)

( Fig. 11 )

This is a long-looped brachiopod, characterized externally by very prominent growth lines ( Cooper 1970; Fig. 11 A–C, F). In the studied material it was found on six seamounts and the slope of the Isle of Pines ( Tables 1, 2), with a bathymetric range of 237–852 m ( Fig. 14 ). This is the first record of the genus Campages from the Norfolk Ridge. It has not been found in the vicinity of New Caledonia, and New Caledonian specimens ascribed to its congener Campages furcifera Hedley, 1905 by d’Hondt (1987) belonged to Falax neocaledonensis based on an examination of internal morphology (see Bitner 2008: 437).

Campages mariae was originally described from off Japan and is also known from China and Kei Island ( Hatai 1940; Richardson et al. 1989; Logan 2007). The new finding extends its biogeographical range by about 3000 km to the south.
