Heterotrophic flagellates, centrohelid heliozoa and filose amoebae from marine and freshwater sites in the Antarctic

Abstract

Heterotrophic flagellates, centrohelid heliozoa and filose amoebae were recorded from cultures derived from water collected at marine and freshwater sites in the Antarctic. Marine samples were collected in the vicinity of Prydz Bay, southeast Antarctica and freshwater samples from Sombre Lake on Signy Island and Crooked and Druzhby Lakes in the Vestfold Hills. Thirty-five species were identified. One new species, Kiitoksia kaloista (Protista incertae sedis), is described. The other species have been previously reported from other geographic locations, providing no evidence for endemism in protozoan species found in Antarctica.
