Taxonomic Study Of The Eupteryx Complex From China (Hemiptera:Cicadellidae:Typhlocybinae:Typhlocybini)

This thesis deals with the taxonomy and geographic distribution of the Eupteryx complex in China.The studying history,economic significance,materials and methods,taxonomic characteristics,geographic distribution in China and identification of the Eupteryx complex are introduced in detail.In the part of taxonomy,6 genera,4 subgenera and 103 species from China are recorded,including 19 new species,2 new records,1 new combination and 1 new generic synonym,with proposing key to genera and keys to species in each genus,providing habitus photographs of 21 species and illustrating male genitalic characteristics of 22 species.Zoogeographical analysis indicates that the species in Oriental Region are far more than in Palaearctic Region,in terms of Oriental Region,most species were found in South China,especially in Southern Yunnan and Fujian,followed by Central and Southwest China.Relatively most species in Palaearctic Region were distributed in North China,so far any species has not recorded in Northeast China,and few species were reported in Qinghai-Tibetan and Mongolia-Xinjiang.The analysis above shows that the distribution of the Eupteryx complex in China is unbalanced,in order to perfect its geographic distribution,we need to increase the extent of survey to the species of different Subregion.The results of taxonomic identification as follows:New species: Aguriahana multiserriformis sp.nov.,Aguriahana Tibetensis sp.nov.,Eupteryx(Eupteryx)brunneus sp.nov.,Eurhadina(Eurhadina)nigbrunneus sp.nov.,Eurhadina(Eurhadina)octomaculata sp.nov.,Eurhadina(Eurhadina)longia sp.nov.,Eurhadina(Singhardina)curvlunaris sp.nov.,Eurhadina(Singhardina)simplicissimus sp.nov.,Eurhadina(Singhardina)foliolata sp.nov.,Eurhadina(Singhardina)flaviscutella sp.nov.,Eurhadina(Singhardina)digitiformis sp.nov.,Eurhadina(Singhardina)thallodialis sp.nov.,Eurhadina(Singhardina)mitis sp.nov.,Eurhadina(Singhardina)pararubra sp.nov.,Eurhadina(Singhardina)coralliformis sp.nov.,Eurhadina(Singhardina)uappenda sp.nov.,Eurhadina(Singhardina)denpendsaliciata sp.nov.,Eurhadina(Singhardina)furca sp.nov.,Eurhadina(Singhardina)uncinata sp.nov.New records: Aguriahana nepalensis Thapa,1989 rec.nov.,Eurhadina(Singhardina)zadyma Dworakowska,2002 rec.nov.New combination: Aguriahana meifengensis(Chiang,Hsu & Knight,1989)comb.nov.transferred from Bellpenna.New synonym: Bellpenna Chiang,Hsu & Knight,1989(= Aguriahana Distant,1918)syn.n.The type specimens of the new species are deposited in the collections of the Entomological Museum,Northwest A & F University,Yangling,China.
