Distribution England, Germany, Greece, Iran (Fig. 1 ), Italy, Kyrgyz Republic, Spain, Tajikistan, Uzbekistan ( Kehlmaier 2005a , Kazerani et al. 2017 , Skevington 2020 ). Notes Our single DNA barcode of Eudorylas auctus from Germany (JSS15405) overlaps with barcodes of E. obscurus from France (CNC464954) and E. longifrons from Iran (GB: LT671752). The genitalia of these species are different, so this is likely just a case of incomplete lineage sorting due to ancestral hybridisation or the fact that these are young species whose barcodes have not yet diverged, as seen in many other taxa (e.g. Skevington 2005 , Skevington et al. 2007 , Young et al. 2016 ). It does raise the possibility that these three taxa are part of a single variable species with polymorphic genitalia. Future work should explore population genetics within this cluster of species, perhaps using the rapidly evolving marker, ITS2.
