No Taxon ("Nematocera" (Non-Brachycera))
Infraorder Bibionomorpha (Gnats, Gall Midges, and March Flies)
Habitat
Generally terrestrial, in contrast to other Nematocera which are predominantly aquatic.

Probably not a monophyletic assemblage. Ordered this way for convenience, based on the Tree of Life.

Most of the species, genera, and families belong to superfamily Sciaroidea, the fungus gnats and gall midges, which probably is monophyletic.
