New and little-known species of soil mites of the families Oppiidae and Suctobelbidae (Acari: Oribatida) from Korea

Both families studied here, Oppiidae and Suctobelbidae, are diversely represented in the northern hemisphere, but these groups are insufficiently studied in Korea. Herein, we propose two new species, Ramusella (Insculptoppiella) ermilovi sp. nov., Medioxyoppia jejudoensis sp. nov., and provide supplementary descriptions of 11 little known species, Graptoppia (Stenoppia) crista Ohkubo, 1996, Multioppia glabra (Mihel & ccaron;i & ccaron;, 1955), Ramusella curtipilus Hammer, 1971, Quadroppia (Coronoquadroppia) monstruosa Hammer, 1979, Suctobelbella amurica (Krivolutsky, 1966), Suctobelbella granifera Chinone, 2003, Suctobelbella nitida Chinone, 2003, Suctobelbella (Flagrosuctobelba) aokii Chinone, 2003, Suctobelbella (Flagrosuctobelba) chabarica Rjabinin, 1975, Suctobelbella (Ussuribata) chinonei Subias, 2017, and Suctobelbella (Ussuribata) variosetosa (Hammer, 1961), which are newly reported from Korea. All species are inhabitants of litter and soil from various types of forests in Korea.
