记述了采自云南省昆明和西双版纳的土壤甲螨31种,其中包括4新种,圆软肛甲螨Chaunoproclus orbiculalus sp.nov.多毛阳甲螨Sund azeles mulliselus sp.nov.,胀圆单翼甲螨Peloribaleslurg idus sp.nov.,宽翼爪甲螨Unguizeles curyplerus sp.nov.和2中国新纪录种:爪哇隆奥甲螨Condylop pia condylifer(Hammer,1979)、散小盾珠甲螨Suclobelbella dispersoselosa Hammer,1979.

The present paper deals with 31 species of oribatid mites including 4 new species and 2 newly recorded species from Kunming and Xishuangbanna of Yunnan Province,China.The types are deposited in the Department of Biology,Norman Bethune University of Medical Sciences.1.

Pergalumna sp.Chaunoproctus orbiculatu sp. nov. (figs. 7-12)Body length 668(685)716tim,width 516(550)604μm.The present new species is closely related to C. minor (Balogh, 1958) from Angola, but Chaunoproctus orbiculatus readily distinguished from C. minor by: 1 ) sensillus comparatively short,its head capitate;2)notogastral setae p2and p3 narrow phylliform in shape;3)the large body size(685μm,in average length).Holotype and 4 paratypes (92-1790), 17. V . 1992,Xishan,Kunming. Sundazetes multisetus sp. nov. (figs. 13-19)Body length 430(439)456μm,width 312(329)344μm.This new species is simillar to S. crispus Hammer,1979 from Indonesia, but distinguished from the latter by: l)sensillus with barbation unlaterally and a pointed tip;2)with one pair sac-culi;3)all notogastral setae barbed ; 4)setal formula of epimerata seemingy:3-1 -5-6(5).Holotype and 3 paratypes (92-1791) ,20. V . 1992,Xishuangbanna. Peloribates lurgidussp. nov. (figs. 20-24)Body length 250(278)300μm ,width 192(202)216nm.This new species somewhat resembles Peloribates nishinoi Aoki,1977 from Japan in notogastral and interlamellar setae distinctly swollen at tip,but can be distinguished from latter by:1)notogastral and interlamellar setae weakly barbed ;2)sensillus is barbed and long;3)the smaller in total length.Holotype and 10 paratypes (92-1799) ,20. V . 1992,Xishuangbanna. Unguizetes curypterussp. nov. (figs. 25-29)Body length 910(944)960μm.width 736(766)800μm.This new species very near to Unguizetes clavatus Aoki,1967 from Thailands ,but easily distinguished from latter by:l)Pteromorphae comparatively spacious liguliform,which anteriolateri-or margin streches to the front ;2)setal formula of eoimerata seemingy:3-1-3-3;3)large in total length :4)differs in the arrangement of genital setae.
