Rhagionemestriidae
Rhagionemestriidae is an extinct family of brachyceran flies known from the Jurassic and Cretaceous periods. It was first named as a subfamily of the Nemestrinidae by Ussatchov (1968), and was raised to full family status by Nagatomi and Yang (1998). They are considered to be closely related to the family Acroceridae. Similar to Acroceridae, members of the family possess a large hemispherical head, with eyes covering nearly all of the area.
