Distribution and area of endemism of Catantopidae grasshopper species endemic to China

China was divided into a geographic grids of 150 km×150 km cells and distribution information of 237 Chinese endemic Catantopidae grasshopper species was gathered to construct a data matrix of species×grids.Based on the data matrix,the distributions of Chinese endemic Catantopidae grasshopper species were analyzed.Parsimony analysis of endemicity(PAE) was used to identify areas of endemism.Except a few species in the Tianshan Mountains,most Catantopids endemic to China were distributed in the region of Southwest-Northeast China.In this region,density in the south is higher than in the north.Both South China and Southwest China hold high density of endemic grasshopper species.Qinling Mountains,the Southeast Tibet and the highland in Zhejiang-Fujian have areas of higher density endemic grasshopper species.Eleven areas of endemism were identified.Among them,five were located in the Oriental realm,two in the borderline between the Oriental realm and the Palaearctic realm,one scattered in the Tianshan Mountains and two in Northeast China.The regions and the distribution of these areas of endemism are mostly in congruence with the Chinese zoogeographical region division and fauna,except for several special areas.Taiwan is close to the Middle China region.Most grids of Qinling Mountains and Hengduanshan Mountains formed unresolved units in the cladogram so it was difficult to identify the area of endemism in these two regions.The clades of South and Middle China consisted of several small clades.They can be divided into small areas of endemism.A narrow area,which covers Tengchong,Baoshan,the South of Guizhou extending to Guilin,is an area of endemism which has not been identified in former studies.
