| 摘 要： | 通过比较中国分布的瘤锥蝗科Chrotogonidae和锥头蝗科Pyrgomorphidae10属蝗虫的形态学性状，选择了22个性状对10属蝗虫的系统发育关系进行支序系统学分析。结果表明：从支序图来看这10个属的关系相互交织在一起，不能区别为两个科。笔者建议在蝗虫分类系统中，把锥头蝗科和瘤锥蝗科合在一起作为一个科比较妥当。 |

| Abstract: | After a comparative study on the morphological characters of 10 grasshopper genera belonging to Chrotogonidae and Pyrgomorphidae,22 characters were used in the cladistcis analysis to illustrate the phylogeny among 10 grasshopper genera of Chrotogonidae and Pyrgomorphidae from China.The result shows that these 10 grasshopper genera can not be divided into 2 groups (Families).Based on two reasons:1) the cladistic analysis result shows that the shape of antennae (ensiform or filiform) has a weakly effect on the phylogeny of Chrotogonidae and Pyrgomorphidae;2) a paraphyly on the cladgram is consisted of six genera and five clades,which shows that these six genera have a close relationship,we suggest that Chrotogonidae and Pyrgomorphidae should be verged into one family. |
