Nothorhaphium is a genus of flies belonging to the family Dolichopodidae.

[2][3] It includes four species from Australia and a single species from New Guinea.

[1] Nothorhaphium superficially resembles the genus Rhaphium, but it belongs in the subfamily Sympycninae and is thought to be closely related to the genera Syntormon, Parasyntormon and Ceratopos.

The name of the genus is derived from the Greek νόθος (nóthos, "false"), and Rhaphium.
