Genus Bradysia Winnertz, 1867

When mounted on slides it is easy to identify specimens as belonging to the genus Bradysia . The main character is the shape of the tibial organ on the fore tibia, consisting of a comb-like row of bristles on a united base, distinctly separated from the ground hair of the tibia. Additional characters are a 3-segmented palpus with at least 2 bristles on the basal segment, bare posterior wing veins and a rather long R1 (different from Scatopsciara ). The genus is distributed worldwide in all zoogeographic zones with plant growth and is likely to be the most species-rich sciarid genus of all.
