摘　　要：对螟黄足盘绒茧蜂复合群Cotesiaflavipescomplex (膜翅目 :茧蜂科 :小腹茧蜂亚科 )分布全世界的 5个种和外群侧沟茧蜂Microplitis及荻茧蜂Diolcogaster的 2 5个性状 ,以及复合群 5个种和外群螟蛉盘绒茧蜂Cotesiaruficrus、粘虫盘绒茧蜂Cotesiakariyai、粉蝶盘绒茧蜂Cotesiaglomerata的 2 4个性状 ,分别进行比较研究 ,并运用支序分析的方法探讨该复合群内 5个种种间的系统发育关系。支序分析表明螟黄足盘绒茧蜂复合群是一单系群 ,二化螟盘绒茧蜂C .chilonis和大螟盘绒茧蜂C .sesamiae近缘 ,芦螟盘绒茧蜂C .chiloluteelli和汉寿盘绒茧蜂C .hanshouensis近缘 ,螟黄足盘绒茧蜂C .flavipes相对独立。以上研究表明无论是以近缘属作外群还是以同属其它种作外群 ,所得结果基本上都能反映螟黄足盘绒茧蜂复合群各种之间的分类地位。Based on morphological studies, 25 characters of 5 species of Cotesia flavipes complex (as ingroup) and two genera Microplitis and Diolcogaster (as outgroup), and 24 characters of 5 species of Cotesia flavipes complex(as ingroup) and 3 species of the same genera (outgroup) were separately selected for cladistic analysis in an attempt to assess the phylogenetic relationships among the Cotesia flavipes complex. The results of cladistic analysis indicate that C. flavipes complex are a monophyletic group; C. chilonis and C. sesamiae are more closely related compared with other 3 species; C. chiloluteelli and C. hanshouensis is closely related with one another; C. flavipes is recognized as the independent placement. Whether using the related genera as outgroup or the congeneric species as outgroup in the cladistic analysis, the basically same scheme for classification of the five species of Cotesia flavipes complex was concluded.
