The Embolemidae of Russia and Ukraine are revised. Five species of Embolemus Westwood and one species of Ampulicormorpha Ashmead are recognized in these countries. A new species Embolemus tauricus sp. nov. is described from Ukraine (Crimea Peninsula). Two species of Embolemus, E. pecki Olmi and E. sensitivus Xu, Olmi et Guglielmino, are recorded for the first time in the fauna of Russia (Primorskiy Territory), and E. ruddii Westwood is only known from the European part of Russia and Eastern Siberia (Irkutsk Province).
