Distributed in south-eastern Australia (Kensley et al. 1987), Tasmania (Hanamura 1989); New Zealand, including the Chatham Islands (Yaldwyn 1960) and the sub-Antarctic Region, from the Campbell Plateau and between the Bounty and Antipodes Islands (Webber et al. 1990); 366–1700 m. The records from Australia and Tasmania might belong to a separate species, as published illustrations of specimens from that region (Hanamura 1989; Poore 2004) suggest differences with topotypical material from New Zealand (Yaldwyn 1960, Webber et al. 1990, Ahyong et al. 2011).
