摘　　要：对8种麻蜥外部形态进行主成分分析,可分为4个种组:1)丽斑麻蜥Eremias argus与山地麻蜥Eremiasbrenchleyi;2)快步麻蜥Eremias velox与虫纹麻蜥Eremias vermiculata;3)密点麻蜥Eremias multiocellata、荒漠麻蜥Eremias przewalskii与敏麻蜥Eremias arguta;4)网纹麻蜥Eremias grammica。研究表明丽斑麻蜥前额鳞数不稳定;密点麻蜥莎车亚种Eremias multiocellata yarkandensis可能为独立物种;荒漠麻蜥物种有效性值得怀疑。This paper analyzed the morphological differences among the 8 Eremias species distributed in China. 258 specimens were collected and measured. 15 countable characters were selected to principal component analysis of data reduction. Based on the loudings of the first three principal components, scatterplots were figured out for further analysis. The results showed that 8 species located in three different regions in the scatterplots. They were E. argus species group （E. argus and E. brenchleyi ）, E. velox species group （ E. velox and E. vermiculata ）, and E. multiocellata species group （ E. multiocellata , E. arguta , E. przewalskii and E. grammica ）. The main differences between E. argus species group and other two species groups were presented on fn, pfa, scc, nvll and fprs, and it indicated that E. argus and E. brenchleyi were distinctly different from other species of Eremias. E. velox species group could be distinguished from E. multiocellata species group mainly by the character vbfp. The character pfa was found unstable in E. argus, and in 107 specimens there are five types on the numbers of prefrontal and most of them have 4 prefrontals. This article suggested that the character of prefrontal in E. argus was in the stage of intensive evolution, which indicated the formatting of new subspecies of E. argus. This research also agreed that E. quadrifrons Strauch （1876） was an invalid species. The character sisl could be used to distinguish E. argus from E. brenchleyi, which was regarded as a valid species and this character was treated as the difference to classify different species. E. velox and E. vermiculata could be easily distinguished by the characters nvll and cloy. The character oa indicated E. grammica should be a group independent among all 8 species. The research showed that the difference between E . m . yarkandensis and E. m. multiocellata was sisl and larger than the differences in E. m . multiocellata , E . arguta and E. przewalskii. We speculated that E. m. yarkandensis sh
