文摘

Diatom species Aulacoseira pardata English & Potapova, new for the flora of Russia, has been found in the course of studying samples from Lake Frolikha (Transbaikal region) by scanning electron microscopy. Numerical morphological features of the species in the studied population differ from the type population, which indicates their greater variability. It is shown that A. pardata is distinguished from the similar species A. septentrionalis (Camburn & Charles) Genkal & Kulikovskiy by the shape of spines and shape and size of areolae on the valve mantle. Species A. septentrionalis, new for the lake, as well as for Cis-Baikal and Transbaikal regions, has also been recorded in Lake Frolikha.
