Eremochaetidae
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.

Archisargoidea
} Archisargoidea is an extinct superfamily of brachyceran flies known from the late Middle Jurassic (Callovian) to early Late Cretaceous (Turonian). Most flies in the superfamily have large eyes and an elongated abdomen, preserved females have a sharp, piercing oviscapt used for injecting eggs into host matter. Their relationships with other members of Brachycera is controversial, they are usually considered close relatives of either Stratiomyomorpha or Muscomorpha. Internal relationships between the families are uncertain and the topology of the only cladistic analysis of the family was weakly supported, finding that Archisargidae was paraphyletic with respect to Eremochaetidae and miniaturized Tethepomyiidae. The sharp piercing oviscaps possessed by the group had alternatively been suggested to represent evidence of being parasitoids, injecting their eggs into hosts similar to parasitic wasps Parasitoid wasps are a large group of hymenopteran superfamilies, with ...
