The faunal feature of Guizhou Cercopoidea shows that there are 3 distribution patterns in Zoogeographic Region of the world. 37 species(56.92%) are the Oriental, 27 species (41.54%) are both the Oriental and Palaearctic and 1 species (1.54%) is the Oriental-Australian. This means that the Cercopoidea fauna of Guizhou is the Oriental in general. In the Zoogeographic of China, the fauna can be divided into 13 distribution patterns. There are 15 species known from Huazhong (the Central) Region, which is 23.08%. Species known from both Huazhong and Xinan (the Southwest) are 11 (16.92%) and that from Huazhong, Xinan and Huanan (the South) same as former (11 species, 16.92%).These indicate that species composition of Huazhong, Xinan and Huanan is the faunal feature of Guizhou Cercopoidea in the Zoogeographic of China, in which the Huazhong fauna acts a primary part. In the view of the Zoogeographic of Guizhou, the species of the North Region are 13(20.00%), the South Region 10 (15.38%) ,species known from South,Central and North are 5(7.69%).
