PINSEEL, E. , HEJDUKOVÁ, E., VANORMELINGEN, P., KOPALOVÁ, K., VYVERMAN, W. & VAN DE VIJVER, B. 2017. Pinnularia catenaborealis sp. nov . ( Bacillariophyceae ), a unique chain-forming diatom species form James Ross Island and Vega Island (Maritime Antarctica). Phycologia A recent detailed survey of the Maritime Antarctic diatom flora using a fine-grained taxonomy resulted in the description of many new species of Pinnularia in general and the section Distantes, including the P. borealis species complex, in particular. Moreover, DNA-based studies of P. borealis revealed that many more species need to be described within this complex. During a survey of the freshwater littoral diatom flora of James Ross Island (Ulu Peninsula) and Vega Island in Maritime Antarctica, a previously unknown chain-forming species in the P. borealis species complex of section Distantes was cultured from three different localities.
