New species of Neogene radiolarians from the Southern Ocean – part II

Renaudie, Johan; Lazarus, David B.

Antarctic Neogene radiolarians are well preserved and offer great potential for biostratigraphical, palaeooceanographical and evolutionary studies. Most of the species, however, have not yet been fully documented. In this paper, the second of a planned series, we describe 21 new species of Antarctic Neogene radiolarians: six spumellarians ( Actinomma eldredgei, Actinomma cocles, Anomalacantha? jeapica, Lonchosphaera? suzukii, Pentactinosphaera codonia and Sethodiscus? pravus) and fifteen nassellarians ( Antarctissa evanida, Botryopera chippewa, Botryopera? daleki, Clathrocorys? sugiyamai, Clathromitra lemi, Clathromitra? fulgureanubes, Enneaphormis? sp., Lamprocyrtis? datureacornis, Lophocyrtis pallantae, Lithomelissa? kozoi, Phormospyris loliguncula, Platybursa harpoi, Saccospyris victoria, Protoscenium pantarhei and Trisulcus halipleumon). Most of these species are fairly rare but some can be locally common, and most have restricted stratigraphical ranges within the Miocene or Early Pliocene.
