New and little known species of soil mites of the family Oppiidae (Acari: Oribatida) from Korea.

The oribatid mite family Oppiidae is highly diverse in the northern hemisphere, but in Korea it is represented by only 16 species. Herein, we propose three new species, Moritzoppia coreanasp. nov., Medioxyoppia brevisetosasp. nov. and Medioxyoppia claviacuminatasp. nov., and provide a supplementary description of a little known species, Oxybrachioppia ctenifera, which is newly reported from Korea. All species are inhabitants of the litter and soil of mixed forests, and following the descriptions and comparisons, we discuss aspects of the distribution, diversity of each genus, and habitat ecology of species reported herein.
