Abstract:

Up to now, 3 families, 14 subfamilies, 92 genera, 225 species（subspecies）of Acridoidea and Pyrgomorphoidea, and in which 20 endemic genera（accounting for 21.74%）and 138 endemic species（61.33%）are known in Yunnan, while 4 families, 20 subfamilies, 158 genera, 337 species（subspecies）, 37 endemic genera（23.42%）and 127 endemic species（37.69%）in India. The fact indicates that the two regions have a special and complex fauna composition, and the specificity of Yunnan is more obvious. Richness analysis shows that grasshopper richness of Yunnan is larger than those of India in genus and species levels. Faunistic similarity analysis shows that the two regions have a certain relationship, while retaining their own uniqueness; the fauna components in common are mainly Oriental, then the Ethiopian, while the minimum is Palaearctic component. The species exchange at genus level between Yunnan and India was mainly through the following three routes: the Indo-Malayan subrealm + Indo-Chinese subrealm - Indian subrealm,the Ethiopian realm - Indian block（or Cimmerian block）- Indo-Malayan subrealm + Indo-Chinese subrealm, and the Ethiopian realm - Eurasia - Oriental realm.
