Apystomyiidae is a small family of flies containing the living genus Apystomyia and the extinct genera Apystomimus and Hilarimorphites. The single living Apystomyiidae species, Apystomyia elinguis, is native to California. Species of Hilarimorphites have been described from Mid to late Cretaceous Burmese and New Jersey ambers, while the single Apystomimus species is from the Late Jurassic of Kazakhstan.

==Taxonomy== The genus Apystomyia was first collected in the 1940s, described in 1950 and long placed into the bee-fly family Bombyliidae. The first specimens seen after the 1940s type series were collected in 2005. A study in 1993 suggested the genus was a sister-group to Eremoneura, while placement of the genus into Hilarimorphidae or allied to Therevidae was suggested in 1994. Conversely a new family, Apystomyiidae, was erected for the genus by Nagatomi and Liu based on the distinct structure of the male and female terminalia. They suggested a closer relationship with Cyclorrhapha. This placement was solidified and refined via molecular phylogenetic studies in 2010 which placed the genus as a sister of the Cyclorrhapha within the clade Eremoneura.
