This is confusing because it seems to combine a ptilinal suture with complex wing venation. The first is unique to the Cyclorrhapha, but Cyclorrhapha have simplified wing veins relative to lower Brachycera. In North America we have similar wasp mimics in Syrphidae:Ceriodini and Conopidae:Conopinae. The long beak is consistent with Conopidae.
