Cave-dwelling springtail studies in Korea initiated during 1960s by the Japanese Collembola researcher, R. Yosii, and comprehensive taxonomic studies on Korean Collembola were conducted by B. H. Lee during 1970-1990s wherein the new family Gulgastruridae was established using the type species Gulgastrura reticulosa from the Gossidonggul cave in Gangwon-do, South Korea. Eight families of cave-dwelling Collembola are known in Korea, and the family Tomoceridae is the most abundant and diverse group of cave-dwelling Collembola with 11 known species belonging to 4 genera in Korea. In this study, 12 species of Korean Tomoceridae are reviewed, and 1 new species from the genus Plutomurus and 2 new species from the genus Tomocerus are described.
