is a brachyceran infraorder of Diptera comprising primarily two large —Tabanidae (horse and deer flies) and Rhagionidae (snipe flies)—along with several smaller affiliated families including Athericidae, Vermileonidae, Austroleptidae, Oreoleptidae, Spaniidae, and Pelecorhynchidae. The group is notable as one of only two brachyceran lineages outside Hippoboscoidea containing blood-feeding () , though they are not significant . Phylogenetic relationships among constituent families remain unresolved.

Distribution

Global distribution across all major biogeographic regions. Neotropical region shows highest diversity with 13 identified areas of comprising five main components: Northern South America, Southeastern South America, Central America, Brazilian Savannah, and Central Andes. Additional consensus areas include six in the Nearctic, two in the Palearctic, three in the Oriental, three in the Australian, and three in the African regions. The Andean region of South America and southern South America (Chile and Argentina) support distinct Austroleptidae and Pelecorhynchidae faunas.

Diet

Feeding habits vary by . Tabanidae includes that blood-feed on vertebrates. Rhagionidae and most other families are predatory or feed on other organic materials. Specific dietary habits for many smaller families remain undocumented.

Human Relevance

Tabanidae (horse and deer flies) are the most medically and economically significant , causing nuisance biting and livestock irritation. Unlike mosquitoes, tabanomorphs are not important of human . Vermileonidae larvae construct pitfall traps in sandy substrates. The group has been used as a model system for global biogeographic analysis and identifying areas of for conservation planning.

Taxonomic Uncertainty

The phylogenetic placement of Oreoleptidae, Austroleptidae, and Spaniidae within remains controversial with no current consensus. -level classification has been historically fluid, with several small families alternatively treated as of Rhagionidae.

Biogeographic Utility

has proven particularly valuable for biogeographic analysis due to its global distribution, substantial (over 1,300 ), and well-documented collection records. Results from endemicity analyses show strong congruence with bioregionalisation schemes derived from vertebrates and plants, supporting the use of insects in conservation planning.
