Two new species of oribatid mites, Dicastribates tenuisetosus sp. nov, and Liacarus unjangensis sp. nov. are described from Korea. Dicastribates tenuisetosus sp. nov. is easily distinguishable from a single known species, D. heterotrichus (Mahunka, 1984) from Paraguay by the presence of 14 pairs of distallv attenuate notogastral setae, the smooth rostral and lamellar setae, the relatively short and distally attenuating interlamellar setae, the relatively short sensilli with distinctly clavated head, and presence of two and six setae on epimeral region III and genital plate. Liacarus unjangensis sp. nov. can be easily distinguished from most other known species by the very wide lamellae which cover dorsally whole prodorsum, the presence of equal sized inner and outer teeth of lamellar cusps and the minute rostral, lamellar and interlamellar setae.

From the soil samples at Seonginbong in Ulleung Island, Gyeongbuk, Korea, Punctoribates hexagonus Berlese, 1908 is found for the first time in Korea. A diagnostic description of this species with detailed illustration and data on its geographical distribution are presented.

A specimen of the oribatid mite, Gustavia aominensis Fujikawa, 2008, was isolated from litter and soil samples of Sasa borealis at Cheongok Mountain Natural Recreation Forest in Bonghwa, Gyeongbuk, Korea. This is the first record of this species in Korea. We provide detailed illustrations of the diagnostic features of this species relative to the original description as well as a key for Korean Gustavia species along with illustrations.

The present work was dealt with the twelve species of orbatid mites from leaves, stems and stubbles of rice( Oryza sativa L). Among them six species, that is, Protoribates agricola, Scheloribates decarinatus, Scheloribates oryzae, Sacculozets filosus, Punctoribates manzanoensis, and Paralamellobates ceylanica are new ones in Korea. The other species are Epilohmannia palida pacifica, Podorbates cuspidatus, Tricogaulumna nipponica, Peloribate sp., Scheloribates sp., Galumna sp.

The purpose of this study is to investigate the response of the soil mesofauna and ground-dwelling arthropods to vegetation structure and composition in a mountain pasture. The pasture mainly comprised five types of plant communities; Agrostis alba - Phleum pratense community, Poa pratensis community, Festuca ovina community, Rumex acetosella community, and the shrub assemblage comprised Spiraea miyabei-Spiraea salicifolia community. Soil chemical properties including the pH, EC and nutrient levels were influenced by plant communities. Plant-specific responses were observed for bacteria-feeding and plant-feeding soil nematodes. Collembola and Oribatida having the same feeding habit were influenced differently by plants. nMDS showed that the community of ground-dwelling arthropods were separated by vegetation types. Species numbers of arthropods were different among different plant communities. Our results indicate that vegetation structure and composition can influence both abundance of diversity of terrestrial fauna.

This study was carried out from May 1993 to October 1994 to examine diversity of oribatid mites in Namsan and Kwangreung coniferous forests, which were considered to receive different degrees of environmental pressures. Also, environmental factors (pH of soil and rainfall, litter depth, organic matter) were recorded in the two forests. The pH of soil and rainfall were not different between the two forests, but litter depth and organic matter were significantly higher in Namsan than in Kwangreung (p<0.05). The dominant families (>5% of the total densities) were Scheloribatidae(27.3%), Galumnidae(13.4%), Oppiidae (9.9%), Hypochthonidae(7.6%), Suctobelbidae(6.6%), Euphthiracaridae(5.9%) in Namsan and Ceratozetidae(25.9%), Mycobatidae (14.2%), Oppiidae(14.2%), Galumnidae(11.4%), Astegistidae(8.7%) in Kwangreung. The numbers of species were significantly higher in Kwangreung (103 spp.) than in Namsan (74 spp.)(p<0.05). The total densities of oribatid mites were more abundant in Kwangreung (8,709 ind.) than in Namsan (5,899 ind.) and the difference was significant for density in litter layer (p<0.05).

This study was conducted to analyze oribatid mites communities in deciduous forests in Namsan and Kwangreung on which different levels of environmental stresses might press, and to select potential condidate of biological indicator species. In overall, pH was lower in soil than in litter layer. Also soil pH, total nitrate content and soluble sulfate content were significantly higher in Namsan than in Kwangreung (p<0.05). The flora in Namsan and Kwangreung deciduous forests were dominated by Quercus mongolica, and Carpinus laxiflora respectively. It indicated that Namsan was in the lower stage of the floral succession. The number of species of oribatid mites was significantly higher in Kwangreung (39 families, 65 genera and 114 species) than in Namsan (32 families, 53 genera and 89 species) (p<0.05). Common species found in two regions were 77 species. Mean density of oribatid mites was 1.8 times higher in Kwangreung than in Namsan and this difference came mainly from litter layer. Among correlation analyses between environmental factors and oribatid mites density and species number, only density was negatively correlated with fresh litter depth in Namsan litter layer (r=-0.89, p<0.05). The pH which was considered to affect distribution of oribatid mites didn't show significant results.

Hitherto, a total of 112 species of 88 genera under 55 families of oribatid mites were reported from Cheju island. Of these, 76 species were added newly recorded species as the faunal list of the island.
