New data on the digger wasps fauna of families Pemphredonidae, Psenidae and Philanthidae (Hymenoptera: Apoidea) in Iran

The digger wasps fauna (Hymenoptera: Apoidea) of Fars province in southern Iran was partly investigated. Members of three families: Pemphredonidae (5 species of 3 genera), Psenidae (3 species of 2 genera) and Philanthidae (2 species of 2 genera) were collected and documented. The following eight species: Diodontus brevilabris de Beaumont, 1967, D. crassicornis Gribodo, 1894, D. insidiosus Spooner, 1938, Passaloecus corniger Shuckard, 1837, Pemphredon inornata Say, 1824, Mimesa punctipleuris (Gussakovskij, 1937), Psenulus laevigatus (Schenck, 1857) and Cerceris spinifera haladai K. Schmidt, 2000, are new to the Iranian wasp fauna. In addition, two species: Psenulus schencki (Tournier, 1889) and Philanthus variegatus Spinola, 1839, are new records for Fars province. For each species, we include available distributional data as well as comments on its taxonomy and geographical distribution.
