Description
Summary:Artemisina arcigera var. spiceps Rezvoi, 1925 Artemisina arcigera var. spiceps Rezvoi, 1925: 197. The variety was described by Rezvoi from the White Sea, Arctic Russia, 66.7°N 33.3667°E, depth 141 m (type material not identified) for the occurrence of fine spination in about half of its choanosomal subtylostyles. This presumedly would not be the case in the typical variety Artemisina arcigera (Schmidt, 1870: 47 as Suberites , from Prøven, West Greenland, approximate coordinates 72.38°N 55.6°W, holotype ZMUC DEM 213). According to Hentschel (1929: 938) this spination is common in many other specimens of the typical variety and he synonymized the two. This was followed by Koltun (1959: 141). I propose to merge the varieties into the species Artemisina arcigera (Schmidt, 1870). Published as part of Van Soest, Rob W.
