中文摘要：
【目的】 进一步明确中国主产茶区茶树小绿叶蝉种类。【方法】 通过网捕法采集了全国14个省（市）109个地区的茶树小绿叶蝉成虫标本。根据外部形态并结合雄性外生殖器进行种类鉴定。【结果】 共检视5 589号叶蝉雄成虫标本，发现8种小绿叶蝉。其中包括：小贯小绿叶蝉Empoasca (Matsumurasca) onukii Matsuda、锐偏茎叶蝉Asymmetrasca rybiogon (Dworakowska)、拟小茎小绿叶蝉 Empoasca (Empoasca) paraparvipenis Zhang & Liu、波宁雅氏叶蝉Jacobiasca boninensis (Matsumura)、匀突长柄叶蝉Alebroides shirakiellus (Matsumura)等。小贯小绿叶蝉发生最普遍且数量最多，占总检视样品的98.53%。各地小贯小绿叶蝉样品数量占当地样品数量的55.56%-100.00%。锐偏茎叶蝉在重庆市采样点发生较多，占当地检视样品的36.96%-44.44%。其余种类，个体数量极少且分布狭窄。【结论】 我国茶树小绿叶蝉有多个种。除云南、广东、海南、台湾和西藏5个产茶省本研究未涉及外，全国绝大部分茶区的优势种为小贯小绿叶蝉。
英文摘要：
[Objectives] To further clarify the species of green tea leafhopper in the main tea production area of China. [Methods] Specimens of green tea leafhopper in 109 regions of 14 provinces were collected by netting and identified on the basis of differences in external morphology and male genitalia. [Results] A total of 5 589 specimens were collected and classified into 8 species, including Empoasca (Matsumurasca) onukii Matsuda, Asymmetrasca rybiogon (Dworakowska), Empoasca (Empoasca) paraparvipenis Zhang & Liu, Jacobiasca boninensis (Matsumura), Alebroides shirakiellus (Matsumura), etc. The most abundant species was E. onukii, accounting for 98.53% of all specimens collected. E. onukii accounted for 55.56%-100.00% of local samples whereas E. rybiogon mostly occurred in Chongqing city, accounting for 36.96%-44.44% of local samples. Other species comprised only a small fraction of the total sample and had a restricted distribution. [Conclusion] There are several species of green tea leafhopper in China. The dominant species in the main tea producing area (excluding Yunnan Province, Hainan Province, Guangdong Province, and Taiwan Province which were not covered in this study) was E. onukii.
