Lophaster Verrill, 1878 Verrill, 1878: 214; Danielssen & Koren 1882: 440; Sladen 1889: 460; Ludwig 1900: 467; Fisher 1911: 334; Koehler 1921: 143; Djakonov 1950: 63; H.E.S. Clark 1963: 61; Bernasconi 1964: 258; Clark & Downey 1992: 299. Sarkaster Ludwig, 1905: 185. Diagnosis Arms five, cylindrical in cross-section, interradial arcs acute. Abactinal skeleton reticulate, papular areas with multiple pores. Abactinal plates paxillate. Marginal plates in two series, composed of distinct paxillae, larger than adjacent abactinal plates. One series of actinal plates, extending along arm in most species. Comments The re-discovery of Lophaster abbreviatus Koehler, 1908 brings the total number of high-latitude Lophaster species to four (A.M. Clark 1962) including L. gaini Koehler, 1912b, L. stellans Sladen, 1889 (with the subspecies L. stellans marionis ), and L. tenuis Koehler, 1920. Three species have now been recorded from the North Pacific, off the coast of Japan (Mah & Fujita 2020).
