摘　　要：自1990～2004年在对云南省25县(市)现场调查所获取的数据资料和有关文献记录资料的基础上,从分类阶元、宿主种类、不同年龄分布、寄生部位等多角度揭示了云南省小兽体表革螨的物种多样性。到目前为止,整个云南省小兽体表革螨共有10科33属112种,以东洋界中印亚界西南山地亚区种类占明显优势;宿主(小兽)种类繁多,分为9科29属53种。革螨的年龄分布有幼虫、前若虫、后若虫和成虫4个阶段;寄生部位遍布全身。云南省小型哺乳动物(小兽)物种多样性特点决定了云南省小兽体表革螨物种的多样性,反映了小兽体表革螨与其寄生宿主(小兽)之间密切的协同进化关系,体现了云南省物种资源丰富。In the paper, the species diversity of gamaside mites on small mammals in Yurman Province, China, was studied. The data mainly came from the investigation of twenty-five counties （towns） in Yunnan Province and published literatures. The results showed that the species of gamaside mites on the small mammals in Yunnan Province are plentiful and 112 species belonging to 33 genera and 9 families have been found. In the known species, the oriental species are preponderating. Host small mammals are also abundant including 53 species, 29 genera, 9 families. There are four infesting instars observed： larva, protonymph, deutonymph and imago. Almost all parts of the body surface of host small mammals are infested. The high diversity of gamasid mite species in Yunnan Province is close to the abundant species of their small mammal hosts, which imply that there might exist a close coevolution between gamaside mites and their hosts （small mammals）. The results also reflect the fact that Yunnan Province is really a ＂kingdom of animals and plants＂ with abundant species resources.
