The family is contained in Brachycera infraorder Tabanomorpha, and several of its constituent groups have been recently elevated to family rank.
Atherix (and related genera) now comprise the Athericidae, Vermileo (and related genera) now comprise the Vermileonidae, and the genera Austroleptis and Bolbomyia are each now the sole members of their own families (Austroleptidae and Bolbomyiidae).
The subfamily Spaniinae was sometimes accorded family rank, but this is not accepted in the most recent revisionary classification.
