Richardia (fly)

Richardia is a genus of flies in the family Richardiidae. It was first described by French entomologist Jean-Baptiste Robineau-Desvoid in 1830. It occurs from Mexico to Central and South America.

Description
The genus includes species with strongly enlarged heads (hypercephalism) and "eyestalks" (eyes inserted in the lateral projection of the head) such as the males R. telescopica and R. stylops. Stalk-eyed flies in family Diopsidae have their antennae located on the stalk, rather than in the middle of the head as in Richardiidae.
