| 摘 要： | 以黄脊雷蓖蝗为外群，选择20个形态性状对竹蝗属10个种(亚种)的系统发育关系进行分析，并据此探讨了其区系形成．结果表明：竹蝗属可以分为长翅和短翅两个类群，短翅类群包括蒲氏竹蝗、黑翅竹蝗和思茅竹蝗；形态分类中归为短翅类群的贺氏竹蝗是长翅类群中的一个高度特化的种类；中国的西南地区是竹蝗属的分布中心，同时也是其起源和物种分化中心。

| Abstract: | Based on Twenty morphological characters, the phylogenetic relationship among 10 grasshopper species (subspecies) of the Genus Ceracris Walker were studied with the outgroup Rammeacris Kiangsu (Tsai). And the biogeography of the genus is also studied. The results suggested that: The grasshopper species of Ceracris Walker can be sorted into two groups, Short-wing group and Long-wing group. The short-wing group included Ceracris pui Liang, C. fasciata fasciata (Br.-W) and C. fasciata szemaoensis Zheng. C. hoffmanni Uv, which is usually thought to be a short-wing species in the morphological taxonomy, is a greatly specialized species the long-wing Group. The Southwest China is not only the distribution center of grasshopper genus Ceracris Walker, but also the original and speciation center of it. |
