Haplopharyngomyia is a genus of flies in the family Dolichopodidae. It is known from Thailand.
It was originally named Haplopharynx by H.J.G. Grootaert and Patrick Meuffels in 1998. Later, the same two authors found this name to be preoccupied by the flatworm genus Haplopharynx (Meixner, 1938), so it was renamed to Haplopharyngomyia in 1999.
The generic name is derived from the Greek words (, 'simple'), (, 'digestive tube') and (, 'fly').
