Acroceridae Nemestrinidae †Rhagionemestriidae Nemestrinoidea is a small, monophyletic superfamily of flies, whose relationship to the other Brachycera is uncertain; they are sometimes grouped with the Tabanomorpha rather than the Asilomorpha.

They are presently considered to be the sister taxon to the Asiloidea.

One extinct family, Rhagionemestriidae, is also included in Nemestrinoidea.

Both families have unusual and distinctive wing venation by which they can be easily recognized, in addition to other features.
