Remarks: Miranda et al. (2009) redescribed the species and proposed that the specimens identified as Haliclystus auricula Clark, 1863 in Chile (Kramp 1952; Quezada 1969b; Zagal 2004a, 2004b, 2008) and Argentina (Amor 1962; Mianzan 1989a) should be classified as Haliclystus antarcticus (Pfeffer, 1889) . Miranda et al. (2010) used molecular data to propose the life cycle of the species. Distribution in South America: Pacific Ocean, southern Chile , at 37.03°S 73.55°W , at 39.78°S 73.34°W , at 52.65°S 71.45°W (Kramp 1952; Quezada 1969b; Zagal 2004a, 2004b; Miranda et al. 2009); Atlantic Ocean, Argentina , at 42.76°S 65.03°W , at 47.75°S 65.91°W , and at South Georgia Island (Pfeffer 1889; Thiel 1928; Carlgren 1930; Kramp 1961; Amor 1962; Mianzan 1989a; Davenport 1998; Miranda et al. 2009, 2010). Habitat: coastal, found in tide pools on rock and on algae (Kramp 1952; Amor 1962; Quezada 1969b; Mianzan 1989a; Zagal 2004a, 2004b; Miranda et al. 2009).
