Remarks. Rochinia fultoni was described from two males and four females from the east coast of Australia, with one measured male designated as type by Grant (1905). It was subsequently recorded from Western Australia ( Richer de Forges & Poore 2008), and the Solomon Islands and Vanuatu ( Richer de Forges & Ng 2013), and the depth range observed is 314– 456 m. This is a new record for PNG.
