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) .
