Pterodontia is a genus of small-headed flies (insects in the family Acroceridae). There are at least 20 described species in Pterodontia.

 Pterodontia have eyes that are covered in hairs. Their antennae are attached below the middle of the head, and are small, short and inconspicuous. Their mouthparts are small and nearly imperceptible. The tibia have small, atypical spurs. The males have a tooth-like projection on the costal edge of the wing.
