我国及邻近地区斑腿蝗科区系及其起源研究

THE FAUNA OF CATANTOPIDAE AND ITS ORIGIN IN CHINA AND ADJACENT REGION

根据斑腿蝗科（Ｃａｔａｎｔｏｐｉｄａｅ）在我国各动物地理区的种类组成和区系特点，发现华中区和华北区的区系特点不明显，前者为南北成份的混交区，后者特有种可跨区分布，这与蝗虫有明显的区域和地带分布的特点不相符。为此，作者同意马世骏先生把江汉平原、秦阳山山地、辽黄淮平原划为古北区，成为东方区系。根据我国北方种类与前苏联西伯利亚区系关系密切，而极少数种类与前苏联欧洲部分甚至欧洲部分所共有这种事实，认为世界动物地理区划中应把西伯利亚单独作为一个亚区较合适。

According to species compositions and faunal characters of Catantopidae in different biogeographical subregions of China, we discovered that the faunal characters are indistinct both in the Central China subregion and the Northeastern China subregion. Both southern and northern species are distributed mixing with each other in the Central China subregion, and the endemic species in the Northeastern China subregion are also distributed in other subregions. These discoveries are inconsistent with the view grasshoppers have distinct regional distribution characters. So a view of Ma Shijun is accepted here that Jianghanhuai Plain, Huaiyang Mountains of Qinling, Liaohuanghuai Plain are regarded as a part of Palaeartic region, forming the oriental fauna. Based on the fact of that species composition in the Northeastern China subregion is closely related to that in Siberian subregion and a few species are the same as those in Europe, we suggest that it maybe better to deal with Siberia as an independent subregion in zoo geography.
