ABSTRACT. Bembecia khovdensis sp.n. and Bembecia yakovlevi sp.n. from the western part of Mongolia is described and illustrated. The first new species is most similar to B. volgensis O. Gorbunov, 1994, but differs from it in the colour of the vertex, patagia, fore coxa and abdomen, and in the shape of the transparent areas of the forewing. The second new species seems to be close to B. sareptana (Bartel, 1912), but is separable from it by the colouration of the thorax laterally, forewing dorsally and abdomen. In addition, these two species have some differences in the male genitalia. The host plants of the larvae of these two new species remain unknown.

KEY WORDS. Lepidoptera, Synanthedonini, clearwing moths, Bembecia khovdensis, Bembecia yakovlevi, , systematics, new species, Palearctic Region, Mongolia.
