ABSTRACT

Phylogenetic relationships among genera and species of the leafhopper tribe Deltocephalini, with particular focus on the large genus Maiestas, were reconstructed using a data set of 32 species representing eight genera plus five outgroups, three nuclear gene fragments (28S rDNA, Wingless, H3) and one mitochondrial (COI) gene fragment using maximum likelihood (ML) and Bayesian inference (BI). The ML and BI results are well resolved with areas of incongruence restricted to a few branches receiving low support in one or both analyses within a large clade comprising species of Maiestas. The results consistently support the monophyly of Deltocephalini, but indicate that some genera previously defined based on morphology, including Deltocephalus, Maiestas and Polyamia, are paraphyletic.

摘要

叶蝉部落 Deltocephalini 的属和种之间的系统发育关系，特别关注大属Maiestas，使用代表八个属的 32 个物种的数据集和五个外群，三个核基因片段（28S rDNA，Wingless，H3）和使用最大似然法 (ML) 和贝叶斯推理 (BI) 分析一个线粒体 ( COI ) 基因片段。ML 和 BI 结果得到很好的解决，不一致的区域仅限于少数分支，在包含Maiesta物种的大型进化枝中的一个或两个分析中获得低支持。结果一致支持 Deltocephalini 的单系，但表明以前根据形态学定义的一些属，包括Deltocephalus、Maestas和Polyamia是并系群。
