Determination of Crabronidae (Insecta:Hymenoptera) fauna of the Lower Kelkit river basin

In this study, the Crabronidae family (Insecta: Hymenoptera) was investigated faunistically in the Lower Kelkit Basin (Amasya, Sivas, Tokat). Totally, 1759 Crabronidae specimens were collected from their natural habitats in the region between 2012 and 2017. 155 species were identified. Results show that 42 species (3 species from Astatinae, 11 species form Bembicinae, 22 species from Crabroninae, 1 species from Dinetinae , 4 species from Pemphredoninae and 1 species from Philanthinae subfamily) were new for the studied region. Lindenius major de Beaumont, 1956; Mimesa bicolor (Jurine, 1804) and Stizus continuus (Klug, 1835) were new species records for Turkish fauna. A short description for these species were given by examining the specimens collected. For each taxon; material examined, distribution of the species in the World and Turkey is given in a table and also Turkey distributions were marked on a map. The results are discussed from the faunistical standpoint and the number of species that newly recorded from the region were compared that of literary data by a table.
