柳二十斑叶甲两亚种比较形态学研究(鞘翅目,叶甲科,叶甲亚科)

柳二十斑叶甲包括两个亚种,分别为指名亚种和高山亚种.两者可以通过头部、前胸背板、足和鞘翅的斑纹区分开来.本文对这两个亚种的外部和内部的形态结构进行了研究,主要包括触角、口器、中胸、后胸、后翅、足、雌雄外生殖器、成虫和幼虫的相关结构.并对确定亚种的形态特征进行了探讨.

COMPARATIVE MORPHOLOGY OF TWO SUBSPECIES OF CHRYSOMELA VIGINTIPUNCTATA ( SCOPOLI ) (COLEOPTERA,CHRYSOMELIDAE,CHRYSOMELINAE)

Chrysomela viginCh. Vigintipunctata alticola Wang. They can be distinguished by the color of head, pronotum, legs and markings of elytra.But it seems too simple to con firm the rank of two species. In present paper, the majority of external and internal morphological structures, including antennae, mouthparts, thorax with wings and legs, male genitalia, female genitalia, some larval and pupae structures are discussed in detail. Also the characters using to confirm subspecies are discussed.
