Data from COI suggest that the Nearctic species are a cluster of recently diverging species. This gene did not exhibit enough sequence diversity to explore species limits or phylogenetics of the genus (Skevington, unpublished data). More rapidly evolving genes or gene regions such as ITS (internal transcribed spacer) and parts of the genes coding for rudimentary (

is clearly an important next step to research on this group of flies. This phylogeny will be useful for interpreting the interesting biogeographical pattern (essentially restricted to the Palaearctic and Eastern Nearctic Regions) exhibited by this genus. It will also serve as an important tool for understanding host­parasitoid relationships as more of these flies are reared.
