Microdon (Chrysidimyia) chrysidimimus (Hull)  

Chrysidimyia was described for a small, metallic green fly with dense punctation that had an "astonishing resemblance" to chrysidid wasps (Hymenoptera: Chrysididae). Thompson et alia (1976: 59) treated it as a synonym of Microdon as it is only one of a couple of species groups of metallic green chrysidid mimics (from Cheng and Thompson 2008).
