Abstract: 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.
