An additional study of the morphological features of the frustule of Eolimna aboensis was carried out. Images of the valves from the author's icon library obtained during the study of phytoplankton of Karelian lakes using scanning electron microscopy were used as the material. A comparative analysis of a number of qu-alitative features (the structure of the areolae and the raphe-sternum) made it possible to clarify the systematic position of this species and transfer it to a genus Sellaphora.
