A list of 208 digger-wasp species (Hymenoptera, Apoidea: Ampulicidae, Sphecidae, Crabronidae) from the Black Sea coast and adjacent areas within Krasnodar Territory, Abkhazia, and Adygea is given. Gorytes schmiedeknechti Handlirsch, 1888, Miscophus albufeirae Andrade, 1952, Psenulus fulvicornis (Schenck, 1857), and Passaloecus pictus Ribaut, 1952) are new to the Russian fauna, and 47 species are recorded for the first time from Abkhazia. Ectemnius guttatus (Vander Linden, 1829) does not occur in the Western Caucasus; the record of the species from this region was based on a misidentified female of E. lituratus Pz. Tachysphex gibbus Kohl, 1885, stat. n. is considered a distinct species based on its ecological and morphological features.
