| description | A new diatom genus <i>Cymbosellaphora</i> Kulikovskiy, Glushchenko, Genkal and Kociolek gen. nov., was described with species <i>Cymbosellaphora vietnamensis</i> Glushchenko, Kulikovskiy and Kociolek sp. nov. <i>C. vietnamensis</i> sp. nov. was described from Vietnam and characterized by the presence of morphological features such as valves with naviculoid symmetry, slight dorsiventrality, the presence of tectula as pore occlusions, uniseriate striae, and a very broad mantle. Four species were transferred to the new genus. These are <i>C. absoluta</i> comb. nov., <i>C. circumborealis</i> comb. nov., <i>C. geisslerae</i> comb. nov., and <i>C. laterostrata</i> comb. nov. Previously, these species were members of genera <i>Navicula</i> Bory, <i>Sellaphora</i> Mereschkowsky, and <i>Naviculadicta</i> Lange-Bertalot. The taxonomic history of these species and genera are discussed. The tectulum is known only from the cymbelloid diatoms, and our new genus is placed within the Cymbellaceae. The presence of a tectulum demonstrates that these species cannot be placed in <i>Sellaphora</i>, as indicated in the literature. The recent proposal to transfer a large number of species with different morphologies to the genus <i>Sellaphora</i> is also discussed. Additionally, we compare pore occlusions with tectula between different genera of the Cymbellaceae with naviculoid symmetry. |
