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.
Description
[edit]As nematoceran flies, sciaroid adults generally have long segmented antennae, while their larvae have a well-developed head and mouthparts.[1]
Aside from this, sciaroids vary in appearance. For example, Sciaridae adults have each eye extended dorsally to form an "eye bridge", a feature not found in related families.[2] Cecidomyiidae adults have a distinctive reduced wing venation, while their larvae are atypical for nematoceran larvae in having a very small head capsule.[3]
Ecology
[edit]Most fungus gnats (Sciaroidea excluding Cecidomyiidae) live in forests with their larvae occurring in fungi, dead wood and soil. There are some which live in wetlands such as fens.[4] Several genera of Sciaridae and Mycetophilidae may reach high abundances in damp buildings with wet organic matter.[5]
Some species of Sciaridae and Cecidomyiidae are among the rare Diptera that spend their entire lives in soil. These are wingless as adults.[6]
Sciaroid larvae typically feed on fungi but there are some which form plant galls (many Cecidomyiidae) or prey on other invertebrates (Keroplatidae).[7]
Phylogeny
[edit]A 2016 molecular phylogenetic analysis confirmed that Sciaroidea is a monophyletic group and should include both Cecidomyiidae and Ditomyiidae.[8]
Families
[edit]These 15 families belong to the superfamily Sciaroidea:[9]
- Bolitophilidae Meigen, 1818
- Cecidomyiidae Newman, 1835 – gall midges and wood midges, sometimes excluded from Sciaroidea
- Diadocidiidae Winnertz, 1863
- Ditomyiidae Kylin, 1919
- Keroplatidae Rondani (incl. Lygistorrhinidae Edwards, 1925) – long-beaked & predatory fungus gnats
- Mycetophilidae Newman, 1834
- Rangomaramidae Jaschhof and Didham, 2002 – long-winged fungus gnats[10]
- Sciaridae Billberg, 1820 – dark-winged fungus gnats
- † Antefungivoridae Rohdendorf, 1938
