中国颖蜡蝉科(半翅目:蜡蝉总科)昆虫区系研究

Fauna of Achilidae(Hemiptera: Fulgoroidea) in China

为了解我国颖蜡蝉科29属123种昆虫的区系分布情况,探讨其起源和演化原因,依据中国颖蜡蝉科地理分布数据,研究其区系组成特点,并运用SPSS 20.0软件进行聚类分析.结果表明,中国颖蜡蝉科昆虫属级、种级阶元在世界动物地理区划中以东洋区所占比例最高(属级占96.55%,种级占91.86%),在中国动物地理区划中以华南区和华中区分布为主(属级分别占89.65%和68.96%,种级分别占54.47%和49.59%).此外,聚类分析显示华南区和华中区物种相似性最高,区间联系最为密切,推测这两个区为我国现生颖蜡蝉科昆虫分化中心和汇集中心.中国颖蜡蝉科区系起源和演化的基础主要归因于地质构造,而我国现生颖蜡蝉科目前的分布格局则主要受植被分布、复杂的地理环境和诸如第四纪冰期活动等气候因素的影响.

To study the distribution of Chinese Achilidae which consists of 29 genera and 123 species, and the reason of faunal ori-gin and evolution, the characteristics of its faunal structure was analyzed using fauna method based on geographical distribution dataof Chinese Achilidae, and the region′s dendrogram using SPSS 20.0. The results showed that Chinese Achilidae was mostly distribu-ted in the Oriental region in zoogeographic region worldwide in generic and specific level, which occupied about 96. 55% and91.86% of the total number of genera and species, respectively. In all zoogeographic regions within China, southern China and cen-tral China were 2 dominant regions for Chinese Achilidae, occupied about 89.65% and 68.96% of the total number of genera and a-bout 54.47% and 49.59% of the total number of species for 2 regions. In addition, cluster analysis showed that southern China andcentral China were the differentiation and assembling center for extant Chinese Achilidae with the highest specific similarity and thestrongest connection. Geological structure was the basal factor for the origin and evolution of Chinese Achilidae. And current distribu-tion pattern of Achilidae in China was mainly developed by vegetation distribution, complex geographical conditions and climaticcondition such as Quaternary glacier movement, etc.
