The Sciaridae, fungus gnats, are a group of small flies that mostly feed on decaying organic matter. They are characterised by wings with a short costa, a single short crossvein r-m near the base of the wing, two strongly sclerotised R veins and weakly sclerotised forked M and Cu veins (Mohrig & Menzel 2009).
Characters (from Steffan 1981): Small flies, 1.0–11 mm long, usually blackish, brownish, or yellowish. Compound eyes usually forming dorsal bridge above antennal bases. Wings hyaline or fumose, sometimes reduced or absent. C ending between apices of R
5 and M
1; Sc weak, ending free; CuP, A
1, and A
2 poorly developed; crossvein r-m in line with R
5; M and CuA forked; crossvein m-cu absent. R and its branches setose above; most other veins sometimes setose above; some veins sometimes setose below. Halter absent in wingless females. Tibiae with one or two apical spurs. Abdomen cylindrical and usually strongly tapering in female.
