贵州省关岭县叶蝉科昆虫区系分析

Faunal Analysis of Cicadellidae from Guanling,Guizhou Province

通过对贵州省关岭县66种叶蝉进行区系分析,结果表明:66种关岭叶蝉在世界动物地理区划中有10个区系型,其中以东洋界区系型为主体,种数为31种,所占比例46.97%;其次为东洋界—古北界区系型,种数为23种,占34.85%;按含特定地理区的跨区区系型复计种数和复计比例来看,纯东洋界区系型所占比例最大,其次为含古北界的跨区区系型.66种关岭叶蝉科昆虫在我国动物地理区划中的归属共计20种类型,其中以华中区特有种所占比例最高,计13种,占19.70%;其次为华中区—西南区—华南区种类,计9种,占13.64%.分析结果表明66种关岭叶蝉昆虫在世界动物地理区划中以东洋界为主,在中国动物地理区划中以华中区所占比例最大.

In the present paper with the leafhoppers,which were collected from Guanling in Guizhou Province,66 species belonging to 7 subfamilies of 43 genera were included.The faunal structures of the leafhoppers（66 species） were studied.It constituted 10 types of distribution in Zoogeographic regions in the world.Among them,31 species distributed in Oriental region,which made up 46.97%;23 species distributed in Oriental-Palaearctic region,which made up 34.85%.It was clear that Oriental species made up the majority of the Guanling leafhoppers at specific level.66 known species of the Guanling leafhoppers constituted 20 types of distribution in seven Chinese Zoogeographic sub-regions.Among them,13 species were present only in Central China sub-region,accounting for 19.70%;9 in Central China＋South China sub-region,accounting for 13.64%.It was obvious that Oriental species made up the majority of the Guanling leafhoppers at specific level and they distributed mainly in Central China Sub-region.
