In the present study, new data about the distribution of 27 species of digger wasps (Hymenoptera: Spheciformes: Crabronidae) collected from different regions of province (southeast Iran) are presented. The specimens were collected at 21 localities using Malaise traps during March to September 2017. The identified species belong to three subfamilies: Bembicinae (three genera, seven species), Crabroninae (seven genera, 18 species) and Philanthinae (single genus, two species). Among them, two species, Gastrosericus moricei E. Saunders, 1910 and G. sabulosus Pulawski, 1995 are newly recorded for the Iranian fauna. Photographic illustrations of morphological characteristics of the newly recorded species are presented.
