abstract = {Five strains of a hitherto undescribed diatom genus Psammoneis were established from Japanese and Senegalese marine benthic samples. Strains were analysed using nuclear-encoded sequence markers and morphometric parameters of their silica frustules. Valves of all strains show a sternum with striae perpendicular thereupon, typical for pennate diatoms. They possess apical pore fields and lack a raphe, typical for araphids, but also rimoportulae and areola occlusions. Sequence comparison of both the SSU rDNA and the D1/D2 region of the LSU rDNA revealed that the strains group into three markedly distinct genotypes. The strains from different genotypes are also distinguishable by a principal component analysis using four morphometric variables measured on the external valve surface. They are described as three new species in a new genus Psammoneis as P. japonica, P. pseudojaponica and P. senegalensis. Molecular phylogenies support placement of the genus Psammoneis as a member of the Plagiogrammaceae. However, this placement renders the family morphologically more heterogeneous, especially with regards to the areola structure. Therefore, we provide an emended description of the family.}
