摘　　要：对中国6种圆瓢蜡蝉Gergithus的外部形态及其雄性外生殖器进行了形态比较研究。结果表明:6种雄性圆瓢蜡蝉体色存在差异,雄虫尾节可分为有刺和无刺2种类型;肛节可根据其端缘凹凸情况分为凹入、近平直和凸出3种类型;6种雄性圆瓢蜡蝉阳茎的结构特征差异最为突出,尤其在其端部的结构上,可作为区别种间的最佳分类依据。此外,本文根据不同形态特征给出了这6种圆瓢蜡蝉的分类检索表,并建议将中胸背板长宽比(2∶1)作为圆瓢蜡蝉属的属征之一。The genitalia and external morphology of 6 male species of the genus Gergithus from China were characterized and compared in this study. The results indicated that ： the body colours of 6 species were different, and the male pygefer can be classified as with thron and without thron ; anal segments was divided into recessed, fiat and bulge on the base of api- cal margin form; the most typical difference of the 6 Gergithus species was the characteristics of aedeagus, especially the structure of apex of aedeagus, and this can be considered as the best basis for distinguishing the species. In addition, the ratio of length to width in mesonotum （2：1 ） can be used as a new characteristic of the genus C-ergithus.
