【摘要】 对蒙古高原合垫盲蝽的物种多样性组成和区系分布进行了研究。结果表明:1.目前,蒙古高原共记录合垫盲蝽23属60种,特有种5种,合垫盲蝽属(Orthotylus Fieber)为优势属17种,占总种数的28.3%;2.从分布的国家看,蒙古20属36种,俄罗斯(图瓦、布里亚特与赤塔州)21属47种,中国(内蒙古和新疆部分地区)20属42种;3.蒙古高原合垫盲蝽区系以古北界成分占主体,仅分布于古北界的13属47种,各占总数的56.5%和78.3%;4.中国蒙古高原合垫盲蝽区系的主体为蒙新区成分,其中单独分布于蒙新区的物种27种,占总种数的64.3%;5.在区域分布上,内蒙古合垫盲蝽的分布特征是内蒙古高原亚区27种>华北亚区26种>阿拉善荒漠亚区23种>嫩江—西辽河平原亚区15种>大兴安岭山地亚区13种>鄂尔多斯高原亚区12种。更多还原

【Abstract】 The diversity composition and faunal distribution of Orthotylinae from the Mongolian plateau were studied in the paper. The results showed that there were 60 species belonging to 23 genera at present. Among of them, five species was endemic species and Orthotylus Fieber was the dominant genus, 17 species, accounting for28.3% of the total species. From the distributional countries, there were 20 genera and 36 species in Mongolia, 21 genera 47 species in Russia(Tuva, Buryatia and Chita), 20 genera 42 species in China(Inner Mongolia and some areas of Xinjiang). In the Orthotylinae fauna of Mongolian plateau, the composition of Palaearctic realm was dominant, 13 genera 47 species distributed there, which accounts for 56.5% and 78.3% of the total known. In China, the main faunal composition of Orthotylinae from Mongolian plateau was the member of Inner Mongolia and Xinjiang region, 27 species was known to be distributed there, accounting for 64.3 %. At the regional distribution, the characteristics of Orthotylinae from Inner Mongolia was the Inner Mongolia Plateau sub-region 27 species > North China sub-region 26 species > Alashan Desert sub-region 23 species > Nen River- West Liaohe Plain sub-region 15 species > Daxinganling Mountains sub-region 13 species > Ordos Plateau sub-region 12 species.更多还原
