Based on abundant material collected recently mostly by Czech entomologists and on previously published data, a review of the genus Tachysphex Kohl, 1883 in Turkey is presented. Four new species are described: Tachysphex prismaticus sp. nov. [T. pompiliformis (Panzer, 1805) complex], T. bouceki sp. nov. [T. mongolicus Kohl, 1898 complex], T. humilis sp. nov. and T. karasi sp. nov. [both T. consocius Kohl, 1892 complex]. Male of T. punctipes Pulawski, 1967 [T. mongolicus complex] is described for the first time. T. grandii de Beaumont, 1965 is recognized as a valid species. Differential diagnosis is provided for T. punctipes, T. consocius and T. grandii. Variability of T. pompiliformis and T. opacus F. Morawitz, 1893 [both T. pompiliformis complex] is discussed. Six other species are recorded from Turkey for the first time. Fifty-two species of Tachysphex Kohl, 1883 are now known to occur in Turkey.
