中国5种常见宽广蜡蝉形态比较研究

为了给农林业生产中的宽广蜡蝉属Pochazia常见种类提供准确鉴别依据,补充广翅蜡蝉科Ricaniidae昆虫分类的形态学资料,对5种中国常见的宽广蜡蝉(眼斑宽广蜡蝉P.discreta、圆纹宽广蜡蝉P.guttifera、柿宽广蜡蝉P.sublimata、山东宽广蜡蝉P.shantungensis和阔带宽广蜡蝉P.confuse)的外部形态和雌雄外生殖器结构进行了比较研究。结果表明:这5种宽广蜡蝉在外部形态特征(体色、身体各部分比例及前、后翅斑纹)、雄性外生殖器构造(尾节、肛节、阳茎干)及雌性外生殖器构造(肛节、第一产卵瓣、第三产卵瓣)上既有相似性,又存在一定的种间差异,这些差异特征可作为种间鉴别的分类依据。5种宽广蜡蝉的雌性外生殖器构造均为首次报道,此外,还给出了这5种宽广蜡蝉的整体形态图、局部特征图和雌雄外生殖器特征图,以及在中国分布的10种宽广蜡蝉分种检索表。

Comparative Morphology of Five Common Pochazia Species from China

In order to provide characteristics for accurate species identification of common Pochazia pests and detailed morphological data for the taxonomy of Ricaniidae, the external morphology, male genitalia and female genitalia of 5 common species(P. discreta, P. guttifera, P. sublimata, P. shantungensis and P. confuse) of the genus Pochazia were collected from China were characterized and compared. The results showed that there were similarities and differences among the 5 species on both external morphological characters(body color, ratio in each section of body, markings of forewing and hindwing), male genitalia(pygofer, anal tube and phallobase) and female genitalia(anal tube, gonopophysys Ⅷ and gonoplac). These characteristics can be used to distinguish these species. The female genitalia of 5 Pochazia species was characterized for the first time. The morphological photographs, illustrations of forewing, hindwing, male and female genitalia of the 5 species, as well as a key to the 10 Pochazia species in China were provided.
