Recent Brachiopoda from the Norfolk Ridge, New Caledonia, with description of four new species Author Bitner, Maria Aleksandra text Zootaxa 2009 2235 1 39 journal article 10.5281/zenodo.190398 5781f612-65d4-4817-8aa7-5091a042a326 1175-5326 190398 Dyscolia johannisdavisi (Alcock, 1894) ( Fig. 6 E, F) This rare species was represented only by a single dorsal valve from Éponge seamount ( Tables 1 , 2) at 707– 777 m ( Fig. 14 ) ( Norfolk 2 cruise). This constitutes the first record from the Norfolk Ridge. Dyscolia johannisdavisi is one of the largest extant brachiopods ― the present valve is 52.7 mm long. In addition to its characteristic large size, the lateral and anterior valve margins are strongly incurved ( Fig. 6 F) and the loop is very short. Dyscolia johannisdavisi was considered to be restricted to the Indian Ocean ( Helmcke 1940 ; Muir-Wood 1959 ; Cooper 1983 ; Hiller 1986 , 1994 ; Zezina 1994 ) until Laurin (1997) recognized it in the area of New Caledonia and the Chesterfield Islands.
