The family Limnorhyphidae was proposed by Hong (1983) for the single genus Limnorhyphus Hong from the Middle Jurassic Haifanggou deposits of Liaoning, China. Hong (1983) placed it near the Olbiogastridae [= Anisopodidae] based on the wing venation. The antennae and wing venation are similar to Scatopsidae and Anisopodidae.
