Lophaster stellans Sladen, 1889 FIGURE 17A–F, 25C Lophaster stellans Sladen, 1889: 460; Ludwig 1903: 27; Koehler 1920: 151; Fisher 1940: 170; A.M. Clark 1962: 50; Bernasconi 1966: 165; 1973b: 310; Clark & Downey 1992: 300 Diagnosis Species showing paxillar spinelets with three or more prongs and marginal paxillae with equal sized spinelets. Comments This species has not historically been recorded from this far north or from the South Pacific region, with most species recorded from the region adjacent to the Antarctic Peninsula and the South Pacific Patagonian region. However A.M. Clark (1962) does record this species from Knox Land in the Victoria Quadrant. Danis et al. (2012) documented this species from 4752 m but without description or imagery, verification of this record was not possible.
