Popis: This electron microscopy study of Achnanthes brevipes from mineralized tributaries (Solyanka, Chernavka, Khara) of the hyperhaline Lake Elton (Volgograd Region) provides new data on the variability of quantitative diagnostic characteristics (valve length, number of striae and areolae in 10 μm). Based on the original and published data, a refined diagnosis of A. brevipes is proposed. It is very similar to A. longipes in valve shape and quantitative characteristics, but striae are multi-row in the latter species and single-row in A. brevipes. A short note about the nomenclature status of A. brevipes is given.
