Mycetophagids, the family of primitive tenebrionoid beetles, are commonly fugivorous. They mainly feed and inhabit in the fruiting bodies of higher fungi, fungus-grown bark, and moldy vegetative materials. Some species are associated with a large variety of moldy substances and are found both outdoors in natural environments and indoors in association with a variety of stored products. They are not serious pests, and their presence is usually indicative of poor storage conditions and moldy produce. There are only five Mycetophagidae species previously recorded for Korea, Mycetophagus antennatus (Reitter 1879), M. ater (Reitter, 1879), M. hillerianus Reitter, 1874, Typhaea pallidula Reitter, 1874, and T. stercorea (Linnaeus 1758). In the course of this study, 60 specimens from 12 sites of Korean Mycetophagidae were examined. We reviewed taxonomically four genera and nine species in Korea. Among them, four species including Eulagius ussuriensis Nikitsky, 1988, Litargus japonicus Reitter, 1877, Mycetophagus irroratus (Reitter,1879), and Mycetophagus pustulosus (Reitter,1889) are newly recorded in Korea. We also obtained additional bionomic data for the seven species including their host fungi and habitat based on field observations and laboratoryrearing data in part.
