Description of four new terrestrial diatom species from Luticola and Microcostatus genera from South Africa

The knowledge about terrestrial diatom assemblages in southern Africa is rather limited, despite a long history of diatom research in this area. Terrestrial habitats are places of characteristic diatom floras, dominated by species resistant to desiccation which are able to thrive in conditions of li...

description The knowledge about terrestrial diatom assemblages in southern Africa is rather limited, despite a long history of diatom research in this area. Terrestrial habitats are places of characteristic diatom floras, dominated by species resistant to desiccation which are able to thrive in conditions of limited water availability. The presented work expands the knowledge about these unique habitats. During the study on terrestrial moss-inhabiting diatoms from Western Cape Province (South Africa), four taxa with a unique set of valve features have been found and described herein as new species, based on light and scanning electron microscopy. These new species are: Luticolamicrocephala M. Rybak, Peszek & Kochman-Kędziora, sp. nov., Luticolaasymmetrica M. Rybak, Kochman-Kędziora & Peszek, sp. nov., Luticolaterrestris Kochman-Kędziora, M. Rybak & Peszek, sp. nov. and Microcostatusmeridionalis Peszek, M. Rybak & Kochman-Kędziora, sp. nov. Algal community composition had low species richness (9–15 taxa per sample) and samples were dominated by: Humidophilacontenta, Nitzschiabrevissima and Eunotiaaff.pseudominor. The three new Luticola species formed numerous populations, exceeding 10% of the share, whereas Microcostatusmeridionalis reached 5.4%. Basic morphological data of associated diatom flora together with detailed micrographs are also provided.
