【Abstract】 The present paper deals with 11 species of Oribatid mites including 2 new species, collected from Mt. Bawangling(alt. 1000m) of Hainan province, China, 24. April. 1992. The types are deposited in Department of Biology, Norman Bethune University of Medical Sciences. 1. Metabelba sp. 2. Megeremaeus rameussp, nov. (figs. 1～4) Body length 686μ, width 412μ. This new species has following important character differences fron all known species of this genus (M. mountanus Higgins et Woolley, 1965 and M. ditrichosus Woolley et Higgins, 1968 from North America; M. expansus Aoki et Fujikawa, 1971 from Japan): 1) sensillus long and with 5—branches; 2) a strong neotrichy in the anogenital region (6—61—2—3); 3) one pair of tubercles excisted; along the anterior margin and posterior margin of apodemata sejugales ; 4)notogastral setae are simple and long. 3. Tectocepheus sarekensis Tragardh, 1910 4. Dolicheremaeus sp. 5. Megalotocepheus hainanensissp, nov. (figs. 5～8) Body length 1192μ, width 648μ. This new species has following characters and is clearly separable from M. Japonicus Aoki, 1965: 1) sensillus rather short, anterior end not reaching of the lateral margin of spd ; 2) co. nl short and rounded triangular in shape; 3) distance between lamella as 2.0×as mutual distance of interlamellar seta; 4) adanal fissures(iad) obliquely aligned. 6. Arcoppia sinensis (Mahunka, 1976) 7. Xylabates spl. 8. Xylobates sp2. 9. Peloribates sp. 10. Scheloribates latipes (Koch, 1844) 11. pergalumna intermedia Aoki, 1966更多还原
