The Opetiidae is a family of true flies of the superfamily Platypezoidea, one of two families commonly called flat-footed flies. The family contains only five extant species in two genera, Opetia from the Palearctic region and Puyehuemyia from Chile in South America. Several fossil genera have been assigned to the family, but many of these are likely to belong elsewhere in the Platypezoidea. Lonchopterites from the Early Cretaceous Lebanese amber and Electrosania from the Late Cretaceous New Jersey amber seem likely to be closely related to modern opetiids.
