Dark winged fungus gnats (Diptera: Sciaridae) collected from shiitake mushroom in Korea

Seven species of sciarid flies were collected in shiitake mushroom farm in Korea. Among them, Lycoriella ingenua (Dufour 1839) and Bradysia difformis Frey 1948 were dominant as possible pests of the shiitake mushroom because the larvae were found on both oak bed logs and in the artificial sawdust beds for shiitake cultivation. Five other species, which were collected in lower numbers, are reported for the first time in Korea: Bradysia longimentula (Sasakawa 1994), Bradysia trispinifera Mohrig & Krivosheina 1979, Leptosciarella (Leptospina) subdentata (Mohrig and Menzel 1992), Scatopsciara camptospina Mohrig and Mamaev 1990, and Xylosciara inornata Mohrig and Krivosheina 1979.
