A recent survey of the non-marine diatoms from islands in the Atlantic sector of the Southern Ocean (King George Hand, Deception Island Livingston Island, James Ross Island, Signy Island, South Georgia and Beak Island) resulted in the description of four new diatom species Chamaepinnularia gerlacher Van de Vijver & Sterken sp nov , Craticula antarctica Van de Vijver & Sabbe sp nov Craticula subpampeana Van de Vijver & Sterken sp nov and Diadesmis australis Van de Vijver & Sabbe sp nov The morphology of each species is described on the basis of light and electron microscopy The new species are compared to similar taxa especially to those present in the Subantarctic and Antarctic Region Preliminary observations on the ecology and biogeography of each species are provided
