中国斑芫菁后翅形态比较

选取中国斑芫菁属11个代表种，对比分析了它们的后翅形态特征； 以苹斑芫菁Mylabris calida Pallas, 1782为模式，探讨了斑芫菁属后翅的翅脉名称，并对其性状进行了描述。研究结果将斑芫菁属翅脉归纳为3种类型：1）南方型：东洋种，翅深褐色，各脉粗大，骨化程度高，皱褶多而明显；2）高原型：青藏高原特有种，翅乳白色，半透明，仅前缘和MP_1＋2形成明显的大翅室，余脉淡而不显，骨化程度低；3）北方型：为以上两种类型的中间过渡，古北种，翅褐色，各脉清晰，中度骨化。根据研究结果，初步探讨了斑芫菁属翅脉的形态进化。

Hind-wing morphology of Mylabris Fabricius (Coleoptera:Meloidae) from China

We selected 11 representative species of Mylabris Fabricius from China,analyzed and compared their hind-wings,and described their morphological characteristics by taking M.calida Pallas,1782 as the mode.As a result,the venations of Mylabris Fabricius were tentatively classified into three types as follows:Southern type,represented by Oriental species,wing dark brown with a lot of folds,veins stout and highly sclerotic;Plateau type,represented by Qingzang Plateau endemic species,wing ivory-white and semitransparent,only the large cell enclosed by costal margin and MP_ 1 2 obvious;and Northern type,as the transition between the former two types,represented by Palearctic species,wing brown,veins clear and moderately sclerotic.At last,the vein morphological evolution of the genus was discussed.
