中国疏广蜡蝉属比较形态学研究

Comparative Morphology of Euricania Species from China

对中国7种疏广蜡蝉(眼纹疏广蜡蝉Euricania ocellus、长刺疏广蜡蝉E.longa、短刺疏广蜡蝉E.brevicula、带纹疏广蜡蝉E.facialis、西藏疏广蜡蝉E.xizangensis、类透疏广蜡蝉E.paraclara透明疏广蜡蝉E.clara)的外部形态和雌雄外生殖器进行较深入的形态比较研究。结果表明7种疏广蜡蝉在外部形态(前翅斑纹、后翅色泽),雄虫外生殖器(肛节形状、阳茎干背刺突长度与阳茎干长度比),雌虫外生殖器(肛节形状、侧面观第三产卵瓣长宽比)方面差异较大。这些特征可用于该类群的物种鉴定与农林害虫防治。另外,还给出了现有标本的6种疏广蜡蝉的整体照片、局部特征照片、雌雄外生殖器特征图,并提供中国7种疏广蜡蝉的分种检索表。

The external morphology,male genitalia and female genitalia of 7 species of the genus Euricania from China,E.ocellus,E.longa,E.brevicula,E.facialis,E.xizangensis,E.paraclara and E.clara were characterized and compared in this study.The results showed that there were obvious differences among these 7 species on external morphology(markings of forewing,color depth of hindwing),male genitalia(shape of anal tube,ratio of dorsal processes to aedeagus),female genitalia(shape of anal tube,aspect ratio of gonoplac in lateral view).These characteristics can be used to species identification and agriculture and forestry control.Moreover,photographs of habitus and part body,illustrations of forewing,hindwing,male and female genitalia of these 6 existing specimens species and a key to 7 Euricania species from China.
