Additions to the knowledge of the digger wasp (Hymenoptera: Spheciformes: Crabronidae) fauna in the Fars Province of Iran

The current paper presents new data on the distribution of 51 species of crabronid wasp (Hymenoptera: Spheciformes: Crabronidae) from the subfamilies Crabroninae (42 species of 15 genera and 5 tribes) and Pemphredoninae (9 species of 6 genera and two tribes) collected at 21 sampling sites in the Fars Province of Iran. Three species, Tachysphex nitidus (Spinola, 1806), Liris memnonius (F. Smith, 1856), and Spilomena mocsaryi Kohl, 1898 are newly added to the Iranian insect fauna. General distribution and Iranian localities are given for each species. The biogeographic affinities of the collected species are also discussed
