In the course of the taxonomic study on onbatid mites from Korea, the author obtained one nau genus, 5 new species, 1 new subspecies, and 5 species unrecorded in Korea for th first time. They are Koreonbates foliatus gen. n, sp. n., Hermannio neotricha sp. n., Xyiobates geonjiensis sp. n., Defectamems sungohi sp. n., Protoripoda flagellato sp. n., Liocarus gommatus coreanus ssp. n., Liocarus polychoihomus Wen, 1991, Tectodamoeus armatus Aok, 1984, T striatus Enami et Aoki, 1988. Oripoda trilabiata Hammer, 1961, and Dometorino tuberculata Aoki, 1984. And keys to the species and subspec~es of genera Liacorus, Defectamems, and Protoripoda are present All the specimens are deposited at the Lab of Plant Protection, Coli, ot Agr, Won Kwang Univ., hi, Korea.

An oribatid mite, Incabates barbatus sp. nov. in the family Haplozetidae is described herein from Korea. This new species is very similar to 1. major reported in Japan. However, prodorsal setae (ro & la) and head of sensillus are smooth in 1. major while barbs are found on the outer margin in the middle of rostral seta (ro) and lamellar seta (la) in addition to the presence of spinulae making the surface of head of sensillus rough in the new species. There are altogether 9 species described in the genus Incubates at present including the new species reported herein and keys to these 9 species are presented.

Two years-study with litter bag (mesh size : 0.4 mm, 1.7 m) was carried out from Nov., 1996 to Sept., 1998 to investigate the soil microarthropod community in the process of needle leaf secomposition of Korean pine (Pinus koraiensis) forest in Namsan and Kwangreung, where were supposed to be under different environmental selective pressures. Soil arthropoda collected from litter bags were sorted into suborders or higher taxa. Acari and Collembola were dominant groups, which were 61-68% and 27-35% of total soil arthropod in their numbers, respectively. Among Acari, Oribatida was major group, and Gamasida and Actinedida were minor groups. Abundance of Acari was a little higher in Kwangreng than in Namsan. But there was not significant difference between the arthropod community structure of Namsan and Kwangreng forest. And the different mesh sizes (0.4 mm and 1.7 mm) of litter bags could not make significantly different community structures in the litter bags. One taxon showed different pattern of population dynalics from another. But Oribatida, Gamasida and Collembola showed peak density in July, 1997. All taxa showed lower population densities in cold season i.e. Nov., Jan. and March. There was not significant difference in decomposition rate between Namsan and Kwangreng forest, and between mesh sizes of litter bags. % residual mass of needle leaf was about 40% at 22 months after litter fall.
