Abstract

The analysis of the type material of Pinnularia divergentissima (Grunow in Van Heurck) Cleve revealed the presence of two distinct Pinnularia taxa in the same slide. Comparison with the original drawing of P. divergentissima by Grunow showed that recent taxonomic treatments of P. divergentissima are not in accordance with the original diagnosis. Both species in the type material are morphologically characterized and the correct identity of P. divergentissima is established whereas the second taxon is described as P. pseudodivergentissima sp. nov. Additionally, the type material of P. fottii J.Bílý et Marvan and P. martinii Krasske is likewise analysed and both taxa are separated from P. divergentissima. Finally, the morphological analysis of a fifth taxon from the subAntarctic Region resulted in the description of a new taxon, P. lindanedbalovae Van de Vijver et Moravcová sp. nov.
