ABSTRACT. A new species, Bembecia fumi O. Gorbunov, sp.n., from the Khangai Mountains of Mongolia is described and illustrated. The type series was bred from larvae and pupae found in the roots of Oxytropis tragacanthoides Fisch. ex DC. (Fabaceae). Based on the structure of the male and female genitalia, this new species belongs to the high-mountain Central Asian group of B. senilis (Groum-Grshimailo, 1890) of the nominal subgenus and is apparently most closely related to B. ceiformis (Staudinger, 1881), from which it differs in the colouration of various body parts and wings, as well as in some details of the structure of the genitalia of both males and females. The types of the new species are deposited in the collection of the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences, Moscow, Russia (COGM).
