The rotifers collected from various terrestrial habitats such as mosses, lichens and mushrooms on tree trunks at four different locations in Korea were investigated. Five species and one subspecies belonging to four genera in three families of monogonont and bdelloid rotifers were identified: Adineta cuneata Milne, 1916, Macrotrachela insolita De Koning, 1947, Macrotrachela musculosa Milne, 1886, Macrotrachela nana nana (Bryce, 1912), Mniobia bredensis De Koning, 1947 and Bryceella stylata (Milne, 1886). All these rotifers are new to Korea, and A. cuneata, M. bredensis and B. stylata are new to Asia as well. Here diagnostic characteristics and illustrations are provided for each Korean new record.
