贵州5种药用豆芫菁形态比较研究

Comparative Morphological Study on Five Medicinal Epicauta Species from Guizhou Province

本文对贵州5种药用豆芫菁外部形态及其雌、雄外生殖器特征进行比较研究,旨在增补和完善该类昆虫的形态特征,为药用芫菁的分类及种类鉴定提供系统全面的参考资料。结果表明:所研究的5种药用豆芫菁的外部形态特征(体长、触角、头部、前胸背板、雄性前足胫节)及雌雄外生殖器构造(阳茎基、阳茎、产卵瓣)在种间既有共性,又存在明显差异,可作为该类药用昆虫物种准确鉴定的主要依据。此外,本文提供了这5种豆芫菁的整体照片、局部特征图及分种检索表。

In order to provide detail data for taxonomy and species identification of medicinal meloids,external morphological characters and genitalia of five Epicauta species from Guizhou province were studied by using comparative method.The results showed that there were similarities and differences among these five species on both external morphological characters（ body length,antenna,head,pronotum,male protibiae） and genitalia（ tegmen,aedeagus and valvifer） and those characters can be availably used in taxonomy and species identification of medicinal meloids. Moreover,photographs of habitus,illustrations of external characters and a key to these five species were given.
