Dexiinae

Uramya halisidotae, copyright Phil Huntley-Franck.

Belongs within: Tachinidae.
Contains: Dufouriini, Dexiini.

The Dexiinae are a group of tachinid flies united by the presence of a hinge in the phallus together with close association of the postgonites with the base of the phallus. Females possess a uterus and deposit eggs containing a developed embryo (Wood & Zumbado 2010). The majority of species parasitise Lepidoptera though certain subgroups attack Coleoptera or Heteroptera. Parasitoids of adult Heteroptera form a clade including the Epigrimyiini and Euthera (Stireman et al. 2019).
