The plants of Actinidia are of great economic importance. And the taxonomy of Actinidia was very difficult and confusing. The genus Actinidia was established by Lindley in 1836 based on the specimen Wallich 6634 collected by N. Wallich in Nepal in 1821. Comprehensive studied on the taxonomy of the genus were carried out by Dunn, H. L. Li, and C. F. Liang.

The members of the same genus and family were grouped together. The polyogenetic relationships of 8 families were Pyrgomorphidae →Chrotogonidae→Pamphagidae→Oedipodidae→Acrididae→Arcypteridae→Gomphoceridae→Cantantopidae.Pygomorphidae had closer relationships with Chrotogonidae as well as being the most ancestral group. Arcypteridae and Gomphoceridae were the sister groups and had closer relationships with most evolutionary Catantopidae. Tridactylidae was divided firstly as a suborder,which differs from the recent taxonomy distinctly. Haglidae and Gryllidae were grouped into suborder Ensifera, Tetrigidae and 8 families of Acridoidea were grouped into suborder Caelifera, as same as recent taxonomy.

Therefore we had some taxonomic research by molecular means in order to supply traditional taxonomy.
