Abstract. In this last paper in our planned series, we describe 25 new radiolarian species from the Antarctic Neogene: 6 spumellarians (Lithatractus? floridus, Spongopylidium? aerostatum, Haeckeliella hederacia, Larcopyle faustae, Excentrodiscus planangulus and E. lappaceus) and 19 nassellarians (Anthocyrtidium sp., Artostrobus? oganeae, Botryostrobus exstructus, Ceratospyris clarki, Cornutella burgundiensis, Cystophormis petrushevskayae, Dendrospyris quadripes, Enneaphormis tippula, Euscenarium funakawai, Lophophaena kamikurii, L. rhopalica, Lychnocanium andreae, Periarachnium pauliani, Peridium tortonianicum, Phormacantha garbela, Phormospyris punnulis, Rhodospyris? morleyi, Rhodospyris pulchra and Tholospyris tautessares). We also report the finding of fragments of an unknown Middle Miocene phaeodarian (Conchellium? sp.).
