摘要:【目的】横纹叶蝉亚属[Pediopsoides (Glaphyropsis)]为半翅目(Hemiptera)叶蝉科(Cicadellidae)宽头叶蝉亚科(Eurymelinae)中的一个小类群,该亚属全世界已知5种,主要分布在东洋区,中国记录4种。对其中两种的形态进行再描述,以进一步理清横纹叶蝉亚属的物种组成。【方法】基于检视标本,采用比较形态学方法结合文献资料,对横纹叶蝉亚属中的薄膜横纹叶蝉[P. (G.) membrana (Zhang, 2010)]和三叉横纹叶蝉[P. (G.) trifurcata (Li, Dai & Li, 2013)]进行了形态学研究。【结果】重新描述了两种叶蝉成虫的形态特征及其雄虫外生殖器的结构特点,并提供了相应的特征图。通过形态学比较发现:薄膜横纹叶蝉特征与前人描述相比,除阳茎侧缘薄膜状突起略有不同外,其余均无差异;三叉横纹叶蝉与山纹横纹叶蝉[P. (G.) montaninversa (Yang & Zhang, 2013)]除阳茎干末端有无一对薄膜状的刺状突起不同外,其余特征无差异。【结论】提议山纹横纹叶蝉为三叉横纹叶蝉的次同物异名。
Abstract: 【Objective】 The leafhopper subgenus Pediopsoides (Glaphyropsis) is a small group belonging to the subfamily of Eurymelinae (Hemiptera: Cicadellidae). The subgenus is distributed in the Oriental region and includes 5 species in the world, of which 4 are known in China. The two species of Pediopsoides (Glaphyropsis) were redescribed in morphylogy to further clarify the species composition of the subgenus. 【Method】 Based on the morphological examination of specimens, the method of comparative morphology combined with literature research was adopted, morphology of P. (G.) membrana (Zhang, 2010) and P. (G.) trifurcata (Li, Dai & Li, 2013) in this subgenus was investigated. 【Result】 The two species of Pediopsoides (Glaphyropsis) were redescribed in the current paper, and their illustrations of the habitus and the male genitalia are also given. According to the comparison of the morphological characteristics: compared with previous descriptions, there were no differences in the characteristics of P. (G.) membrana except that the slightly different shaped membranous processes on both lateral margins of aedeagal shaft; P. (G.) trifurcata and P. (G.) montaninversa (Yang & Zhang, 2013) showed no difference except for whether there were paired membranous spine-like processes at the apex of aedeagus. 【Conclusion】 P. (G.) montaninversa (Yang & Zhang, 2013) is proposed as a junior synonym of P. (G.) trifurcata.
