Systematic Study On Leafhopper Subfamily Stegelytrinae Of The World (Hemiptera: Auchenorrhyncha: Cicadellidae)

The present dissertation mainly deals with the morphology, taxonomy, phylogenetic analysis and biogeography of Stegelytrinae worldwide. The history and present situation of taxonomic research on Stegelytrinae both in China and abroad are outlined, the morphology and terminology of the subfamily, material and methods are introduced. Moreover, phylogenetic analysis and biogeography of Stegelytrinae are expatiated.3 tribes, 22 genera and 81 species are diagnosed and described in the taxonomic part, of which 2 tribes, 14 genera and 63 species are new to science (one genus and 17 species have been published); one new combination and 3 new synonyms are proposed as well. Meanwhile, several genera that could not be assigned previously to certain subfamily such as Cyrta Melichar, Placidus Distant, Doda Distant, Kunasia Distant, Placidellus Evans and Pachymetopius Matsumura, are arranged in Stegelytrinae in the present dissertation based on the phylongenetic analysis. The new taxa are listed as follows.New tribes: Temburocerini trib. nov. and Cyrtini, trib. nov.New genera: Daochia gen. nov., Wuchivuyia gen. nov., Pseudododa gen. nov., Aculescutellora gen. nov., Paradoxivena gen. nov., Platyvalva gen. nov., Minusculacellula gen. nov., Stenolora gen. nov., Truncatategminis gen. nov., Wenchinus gen. nov., Panxinia gen. nov., Qiongtuqia gen. nov., Guduxia gen. nov..
