Type locality: off Japan (34 ° 37 ’ N, 140 ° 32 ’ E), Pacific Ocean. See: Madsen (1961); A. M. Clark & Downey (1992: 98 – 99, figs. 18 g – i, 19 a – b, j, pIs. 26, figs. A – C). Occurrence: cosmopolitan, in the Atlantic, Pacific and Indian deep water (A. M. Clark & Downey 1992); from the Davis Strait and SW of Greenland (Madsen 1961), south to Caribbean waters (A. M. Clark & Downey 1992), eastwards in the Mid-Atlantic Ridge (Dilman 2013) and from the Rockall Trough to Angola (Sibuet 1975), including the Azores and Cape Verde archipelagos (Perrier 1894, Koehler 1909); recorded also from the Meteor seamounts (Madsen 1961, Howell et al. 2003). Depth: 1,444 – 5,430 m (Dilman 2013); AZO: 2,995 – 3,200 m (Perrier 1894, A. H. Clark 1948). Habitat: soft substrates, Globigerina ooze, mud to clay (Koehler 1909, Madsen 1961). Larval stage: lecithotrophic (Ramirez-Llodra et al. 2002). Remarks: Perrier (1885 c, 1894) described Hyphalaster antonii based on a single animal collected by Talisman in the Azores (sta 131, 1883: 38 ° 28 ’ 00 ” N, 25 ° 05 ’ 46 ” W, 2,995 m). In the report on the porcellanasterids collected by Danish-Ingolf expedition, Lieberkind (1935) reviewed the type material of H. antonii and established its synonymy with H. parfaiti, thus confirming previous suppositions that the Azorean species might represent a juvenile of the later species (e. g., Ludwig 1907). Later, A. H. Clark (1948) reported seven specimens of Hyphalaster parfaiti from the archipelago collected by Atlantis (sta 15: 35 ° 37 ’ N, 30 ° 51 ’ W, 3,200 m). In a review of the family Porcellanasteridae, Madsen (1961) placed both Hyphalaster species reported in the Azores in the synonymy of the cosmopolitan Hyphalaster inermis.
