AU known specimens collected in the second half of June. Distribution. Known from Mongolia. Locus typicus: 100 km W from Ovot Chuural, 1250 m a. s. 1. Specific differences. Owing to its small stature and characteristic coloration, the new species differs immediately from its congeners. The female genitalia are especially characteristic. I should mention that the species had been considered by several authors to represent a Lithostege species. Holotype 6 : "MONGOLIA: Südgobi aimak 100 km W v. Grenzposten Ovot Chuural, 1250 m Exp.
