During the SEM study of diatoms in phytoplankton of aquatic ecosystems of the Mordyyakha River basin (Yamal Peninsula, Russia) interesting record was observed. Gomphosphenia stoermeri is a new species for the flora of Russia. Until now, G. stoermeri was known only from a type location in the USA and few rivers in northern Sweden. Morphological observations of the Mordyyakha population of the species revealed the coincidence of the valve dimensions and difference in the number of striae in 10 µm comparing to published data. The paper presents supplemented description of G. stoermeri illustrated by SEM micrographs.
