Several well-preserved theoperid species previously described under the genera Calocyclas, Cyrtocapsella or Theocorys are now grouped into Theocorys, and their phylogenetic relationships are discussed. Five species are described, of which three are proposed as new. They are: T. kerguelensis sp. nov., T. minuta sp. nov., T. saginata sp. nov., T. robusta comb. nov. and T. semipolita comb. nov. In addition, another new species, Calocyclas (?) nakasekoi, is described.completedInvertebrate paleontologyAtlantic OceanbiostratigraphyCenozoicCircum-Antarctic regioncorrelationEoceneIndian OceanInvertebrataLeg 114Leg 120new taxaOcean Drilling ProgramOligocenePaleogenephylogenyProtistaRadiolariarangerevisiontaxonomyTertiaryTheocorysTheocorys kerguelensisTheocorys minutaTheocorys robustaTheocorys saginataTheocorys semipolitaurn:org.iodp:exp:114urnlargerWorkCitationcampaignurn:org.iodp:exp:120urnlargerWorkCitationcampaignEnglishgeoscientificInformation-80.0000147.0000-60.000075.0000Atlantic OceanIndian Ocean
