Eremochaetidae

thumb|Zhenia burmensis Eremochaetidae is an extinct family of brachyceran flies known from the Jurassic and Cretaceous periods of Asia. It is part of the extinct superfamily Archisargoidea. The morphology of the ovipositor of the only 3 dimensionally preserved genus Zhenia was initially interpreted as evidence of being an endoparasitoid of arthropods, however a subsequent study suggested that the ovipositor was used to deposit its eggs in plant material, similar to members of Tephritoidea. In a phylogenetic analysis, Ermochaetidae was found to be monophyletic, surrounded by a paraphyletic Archisargidae.
