In the family Sciaridae, only 3 species have been recorded in Korea, as the pests on various crops and mushrooms in glasshouse (Bradysia difformis Frey, 1948, Bradysia procera (Winnertz, 1868), Lycoriella ingenua (Dufour, 1839)), even though Sciaridae is one of the species-rich families in the order Diptera. There are plenty of species unknown in Korea which are very hard to identify by morphological characters in the larval, pupal stages and also female adults as well. Therefore, using the sequences of cytochrome oxidase I gene (COI) from adult male, we tested the utilities of DNA barcode to identify the species of sciarid flies.
