• Resumen

  • Ninety-eight species of polycystine Radiolaria are recorded in 47 plankton samples collected in an area defined by 36°10.5' S, 39°45.9' S, 54°59.8' W and 49°27.4' W. New names for two actinommid species are proposed and a new species, Acanthosphaera pinchuda n. sp., is established. Most of the species were present in low densities and the spumellarians were dominant over the nassellarians.
