Hybotidae, the typical dance flies, are a family of true flies. They belong to the superfamily Empidoidea and were formerly included in the Empididae as a subfamily.

Hybos culiciformis (Hybotinae)
Ocydromia glabricula (Ocydromiinae: Ocydromiini)
Tachydromia arrogans or closely related species (Tachydromiinae: Tachydromiini)
The Empidoidea are a large monophyletic superfamily of true flies, the sister taxon to the Muscomorpha (Cyclorrhapha). These two groups are sometimes united in the unranked taxon Eremoneura. There are some 10,000 known species within Empidoidea, which are represented on all continents except Antarctica. They are known to have existed since the Jurassic period.
