Empidoidea

Dance Flies, Long-legged Flies, and Allies

is a large superfamily of () comprising approximately 10,000 described across all continents except Antarctica. As the sister to Muscomorpha (), these two groups are sometimes united in the unranked taxon . The superfamily includes several well-known : (dagger and ), (), and Hybotidae (). The group has existed since the period and has been subject to extensive phylogenetic revision, particularly following molecular studies in 2018 that reshaped relationships among constituent families.
