Originally the Therevidae "sensu lato", were polyphyletic. It required the reassignment of some subfamilies to other families, together with adjustments to closely related families in the Asiloidea, to establish consistent phylogenetic relationships. The Therevidae now constitute a monophyletic clade that English-speaking dipterologists call the therevoid clade (clade of "Terevoidi"). This group has not been assigned a ranking at any taxonomic level above the rank of family, but for the present is recognised as a group of families within the superfamily Asiloidea.
