内蒙古合垫盲蝽亚科昆虫生物地理初探

Preliminary study on the biogeography of Orthotylinae (Hemiptera,Miridae) in Inner Mongolia

对内蒙古合垫盲蝽亚科的生物地理学进行了初步研究。内蒙古已知该亚科昆虫20属40种。聚类分析结果表明，内蒙古合垫盲蝽亚科区系可分成3个区域（A，B，C）：区域A仅包括亚区Ⅰ；区域B几乎覆盖了内蒙古大部分的草原和平原地带，它由亚区Ⅱ，Ⅲ和Ⅳ组成；区域C包括亚区Ⅴ和Ⅵ。另外，在38-40°N范围内，内蒙古合垫盲蝽亚科物种最为丰富。

The Orthotylinae biogeography of Inner Mongolia was studied. This subfamily consisted of 20 genera and 40 species in Inner Mongolia. The result of cluster analysis showed that the fauna of Orthotylinae was divided into three regions （A, B, C）. Region A only included sub-region I. Region B almost covered most of Inner Mongolia＇s prairies and plains, which was composed of sub-regions II , III and IV. And region C included sub-regions V and VI. In addition, within the range of 38 ° -40 ° N, Orthotylinae species of Inner Mongolia is most abundant.
