The distribution of 72 Colletidae (Colletes -34; Hylaeus - 38) species in biomes of Mongolia is analyzed. Alpine zone is inhabited by eleven species, mountain-taiga zone by 18 species, mountain steppes and forests zone by 47 species, steppe zone by 35 species, desert steppe zone by 49 species, desert zone by 40 species. Almost a third of the species (21) occur only in one of the zones, mainly in the steppe, semidesert or desert. The remaining species (51) are distributed in two or more zones, with only three species known from all six zones. Endemism is inherent in all zones, however, the true number of narrow endemics (10 species), with further study of the fauna of adjacent territories, is likely to decline.
