New data on distribution of 48 species of Megahilidae in Siberia and neigh­boring regions of Kazakhstan are given. Among them, Anthidium kashgarense (Cockerell, 1911) is a new to Russia and Kazakhstan and Coelioxys latefasciatus Morawitz, 1886 is new to Russia. These two and five more species, namely Anthidium cingulatum Latreille, 1809, Megachile rubrimana Morawitz, 1894, M. pyrenaea Pérez, 1890, Osmia bicornis (Linnaeus, 1758), and O. mustelina Gerstäcker, 1869, are new to Siberia. Regional faunistic lists have been significantly supplemented: Republic of Tyva – 29 new species, Krasnoyarsk Territory – 24, Republic of Khakassia – 19, Altai Territory and Republic of Buryatia – 4 each, Kurgan, Novosibirsk, and Kemerovo provinces – 3 each, and Tyumen Province – 1. There are 109 species of Megachilidae currently known in Siberia.
