Three species of the soil inhabiting pseudoscorpions of the genus Allochthonius [A. buanensis Lee. 1982, A. coreanus (Morikawa, 1970), A. opticus (Ellingsen, 1907)l from Korea. Of these, A. opticus is new for Korean fauna. A. buanensis differs from A. opticus and is confirmed as a valid species based on the carapal chaetotaxy, which is proposed as a considerably stable and useful taxonomic character in genus Allochthonius. The most common species in Korea is A. buanensis, while the other species are relatively rare.
