Derephysia longispina sp. n. is described from the steppe and forest-steppe zones of the USSR. It is closely related to D. cristata (Panz.) but differs from it by the presence of hairs on the lower surface of paranota, rather long and close to each other frontal spines, the elongate triangular process of pronotum with sharp apex, the median cari-na of pronotum slightly falling down behind hood, the glabrous anterior part of pronotal disk.
