中国瓢虫科昆虫的区系分析

ON THE FAUMAL ANALYSIS OF COCGINELLIDAE IN CHINA

中国瓢虫种类已记载有10个亚科22个族83个属530种,以东洋界分布种占绝对优势,共407种,占76.79%.在中国动物区划中,又以华南区种类最为丰富,共208种,占39.25%.在世界动物地理分布区划中,不同地理区的瓢虫科昆虫区系组成差异很大.在亚科级中,小艳瓢虫和小毛瓢虫是世界性分布的类群,但我国已知种类仅占4.53%和25.47%,低于美国和日本;食植瓢虫也是世界性分布的类群,我国已知种类占总数的20.94%,多分布于西南、华中和华南区,东洋界分布种共102种,占食植瓢虫的91.89%.在属级的类群中,大多数的属仅分布于一、二个动物地理区,在中国动物地理区划中也是如此,分布相当局限.一些世界性分布的属,如小毛瓢虫属、瓢虫属和食植瓢虫属,以及一些在我国广分布的,如盔唇瓢虫属、裸瓢虫属和红瓢虫属,其种类组成在各地理区中极不相同.

This paper dealt with the faunal analysis of 530 species of Chinese Coccinellids which were compiled in 'A Check list of the Coccinellidae of China' by the authors. The paper was divided into two parts. In the first part, the generic names of Coccinellids were listed and clearly indicated their distribution in China. In the second Part, the faunal characteristic of Chinese Coccinellids was explicated on the basis of the distribution and cmoparison was made among those in the United States and Japan. They are as follows: 1. The Chinese Coccinellid fauna of the Oriental species was fairly rich (about 43 genera,407 species, and 76.79%) and about 20 genera, 208 species (39.25%) only distributed in the region of Sou them China. 2. It was found that the genus group of Chinese Cocinellids mainly distributed in one or two regions.There were many differences in species composition, even if it belonged to the wide sptead genera.
