Belongs within: Sciaroidea.
Contains: Sciara (Sciara).

The Sciaridae, fungus gnats, are a group of small flies that mostly feed on decaying organic matter.

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 R5 and M1; Sc weak, ending free; CuP, A1, and A2 poorly developed; crossvein r-m in line with R5; 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.
