Brachystomatinae is a subfamily of flies belonging to the family Empididae.[1]
Until 2006, Brachystomatinae was classified as a subfamily within Empididae, at which point a new phylogeny was proposed in which the lineage was raised to family rank,[2] though other contemporaneous studies did not support this conclusion,[3][4] and in 2018 a new analysis indicated that the treatment of Brachystomatinae as a family rendered Empididae paraphyletic, and restored it to the rank of subfamily.[1]
