摘　　要：运用支序分析法探讨了中国隐脉叶蝉亚科Nirvaninae15属的系统发育关系。支序分析选用了41个形态学特征和1个生物学特征。结果表明,在15个属中,薄扁叶蝉属因其前翅革片基部翅脉明显、前缘域具横脉等祖征,为最原始的类群。隐脉叶蝉属+内突叶蝉属与凹片叶蝉属+扁头叶蝉属是最进化的一对姐妹群。从族级水平上看,在现有的4族(隐脉叶蝉族、额垠叶蝉族、棱头叶蝉族及缺缘叶蝉族)中,缺缘叶蝉族与其余3族先构成姐妹群,隐脉叶蝉族与棱头叶蝉族+额垠叶蝉族为姐妹群。依据支序分析的树形图,建议将缺缘叶蝉族、棱头叶蝉族从隐脉叶蝉亚科中移出。The cladistics method is used to analyze the phylogenetic relationships of 15 genera of Nirvaninae (Homoptera: Cicadellidae) from China. The analysis were made using 41 morphological characters and 1 biological character. Results show that: in 15 genera, Stenotortor Baker is the most primitive group and its primitive characters are forewing with veins distinct, costal margin with cross veins; Nirvana+Extensus and Concaveplana+Ophiuchus is the most evolutive sister groups. Balbillini is a sister group of the other 3 tribes, while Nirvanini and Stenometopiini+Mukariini are regarded as a sister group in four tribes of Nirvanae; Based on the cladogram, Balbillini and Stenometopiini should be transferred from Nirvanae, and the systematic position of Kana, Chudania and Convexfronta need to be further studied.
