Abstract: [Objectives]  To further clarify the classification of green tea leafhopper species. [Methods]  Specimens were collected by netting in Guizhou, Chongqing, Hainan and Fujian provinces, and identified on the basis of differences in male genitalia under a stereomicroscope. [Results]  2 988 specimens from 44 tea shrubs were examined and seven species identified; Empoasca (Matsumurasca) onukii MatsudaEmpoasca (Empoasca) limbifera (Matsumura)Empoasca (Empoasca) paraparvipenis Zhang & LiuEmpoasca (Empoasca) hiromichii (Matsumura)Alebroides shirakiellus (Matsumura)Alebroides similis Dworakowska and Asymmetrasca rybiogon Dworakowska. The largest taxa were, in order of abundance, Empoasca (Matsumurasca) onukii Matsuda, 1952 (98.90%), Alebroides shirakiellus (Matsumura, 1931) (0.57%) and Empoasca (Empoasca) paraparvipenis Zhang & Liu, 2008 (0.335%). Other species comprised only a small fraction of the total samples and had a narrow distribution. [Conclusion]  In terms of abundance and distribution, Empoasca (Matsumurasca) onukii Matsuda, Empoasca (Empoasca) paraparvipenis Zhang & Liu and Alebroides shirakiellus (Matsumura) are the most important pest species among the seven species identified. The dominant species on tea plants in Guizhou was Empoasca (Matsumurasca) onukii Matsuda, 1952, it is not certain if the other species were feeding on tea or not. Records of Empoasca (Empoasca) vitis (Göthe) are probably a case of misidentification rather than a change in the dominant species.
