Hesperinus is a genus of flies and the sole genus in the relict family Hesperinidae belonging to the nematoceran infraorder Bibionomorpha. There are about 8 known species, nearly all from the Palaearctic region with one each from the Nearctic and Neotropical regions. Three fossil species from Eocene Baltic amber have been described. These flies have long 12-segmented antennae, legs and abdomen and males have well-developed wings while females have a short one.
