Sciaroidea

The Diadocidiidae are a family of flies (Diptera), containing one extant genus with over 20 species and one extinct genus. Diadocidiidae are found worldwide, except in Africa and Antarctica. They are usually considered close to the Keroplatidae, Bolitophilidae, and Ditomyiidae, and used to be included in the Mycetophilidae. They are woodland flies, found in shaded places in forests or near streams. The larvae spin silken tubes under bark or in dead logs, and feed on hymenium of Polyporaceae fungi. The average body length for adults is around 2.5–5.6 mm.

Lygistorrhininae, commonly called long-beaked fungus gnats is a subfamily of flies in the Diptera family Keroplatidae. The groups was long treated as a separate family, but molecular phylogenetic analysis has shown it to belong to Keroplatidae. There are about 7 genera and at least 30 described species in Lygistorrhininae.

Rangomaramidae is a family of flies in the infraorder Bibionomorpha. The family, members of which are known as long-winged fungus gnats, was erected in 2002 by Jaschhof and Didham to include five new species of flies in the genus Rangomarama from New Zealand. The family was then expanded to include several other genera from across the world which were formerly classified as Sciaroidea incertae sedis, but preliminary studies show that the broad family is non-monophyletic.

Sciaroidea is a superfamily in the infraorder Bibionomorpha. There are about 16 families and more than 15,000 described species in Sciaroidea. Most of its constituent families are various gnats (e.g. fungus gnats).

Bolitophila is the sole living genus in the Bolitophilidae, a family of Diptera in the superfamily Sciaroidea, with around 40 Palaearctic and about 20 Nearctic species, and three species from the Oriental region (Taiwan). They are small (6–9 mm).
