Resumo

A new species of diatoms, Hippodonta makarovae sp. nov., is described using scanning electron microscopy. The new species has a valve shape similar to other species of the genus, Hippodonta hungarica Grunow and Hippodonta pumila Lange-Bertalot, Hofmann & Metzeltin, but differs from them in the main diagnostic quantitative features: the length and width of the valve, the number of striae and lineolae in 10 µm.
