科昆虫地理分布研究初探

本文就科昆虫的起源，各亚科、族及属的分布特点进行了分析和总结；并根据各属的世界分布情况，将其分为８种类型。文中还就中国科昆虫的地理分布及特点作了初步的探讨，结果表明：在我国已知的２亚科４族２０个属中，东洋区分布的有１０个属，其中有３个属仅分布于我国；古北区分布的有１个属；东洋－古北区分布的有３个属；东洋－新北区分布的有１个属；东洋－古北－新北区分布的有４个属；东洋－古北－新北－非洲区分布的有１个属。此外，科昆虫在中国的一个主要分布特点就是多数种类集中分布于华中区、华南区和西南区；而华中区则很可能是科种类的分化中心，并以此为中心向其他区扩散。

A PRELIMINARY STUDY ON THE DISTRIBUTION OF THE FAMILY PERLIDAE (Plecoptera:Perloidea)

In the present paper,the origin of the fa mily Perlidae and the distribution cha racters of the tribe and the subfamily were summarized and analyzed.Based on the distribution of the genera in the world,the eight distribution types of the ge nera were divided.In addition,the distribution characters of the Perlidae in Ch ina were also probed preliminarily.So far two subfamilies,four tribe and twent y genera have been found in China.Ten of them,of which three genera are endemic to China,are the Oriental genera;one Palaearctic genus;three Oriental Palae arctic genera;one Oriental Nearctic genus;four Oriental Palaearctic Nearctic genera and one Oriental Palaearctic Nearctic Afrotropical genus.Moreover,t he main distribution character of Chinese Perlidae is that most of the species d istribute Central China region,South China region and Southwest China region.Th e Central China region centralizes the distribution and the break of the perlid species,and made the dispersal for the others regions.
