摘　　要：对蝉次目3个总科(蝉总科,沫蝉总科,角蝉总科)代表类群(12种成虫)的足、消化道和马氏管的形态结构及其分化进行了比较形态学研究,提出蝉次目昆虫消化道及马氏管整体结构可被划分为两种类型的观点(蝉总科和沫蝉总科消化道及马氏管整体结构为同一种类型,角蝉总科消化道及马氏管整体结构为另一种类型),并分别绘制了两种类型的模式结构图;基于成虫的马氏管比较形态学研究,提出蝉次目昆虫成虫马氏管可被划分为6部分的观点,并分别绘制了角蝉科、叶蝉科、蝉科和沫蝉科成虫的马氏管区域分化模式结构图。研究结果表明,蝉次目昆虫的足、消化道、马氏管的形态、功能分化与其生物学、行为生态学特性等密切相关,其形态学特征既为蝉次目各类群的单系性提供了重要支持证据,也为进一步从行为学、生态学、生物学等方面探讨蝉次目的系统演化历史提供了新的信息;研究结果支持"蝉总科和沫蝉总科为姊妹群"的观点,即蝉次目3个总科的系统关系为"角蝉总科+(蝉总科+沫蝉总科)"。Presented here are the results of the preliminary investigation of the differentiation of the legs,alimentary canals and Malpighian tubules of Cicadomorpha adults and the associations between these organs and their related functions respectively,based on the comparative morphology of 12 species representing three superfamilies.The results of this investigation suggests that：1）the alimentary canals and the associated Malpighian tubules of Cicadomorpha adults could be divided into two types,i.e.,Cicadoidea and Cercopoidea share the same type,and Membracoidea the other（diagrams are provided for each type）;2）six differential regions of Malpighian tubules of Cicadomorpha adults can be recognized,i.e.,filter chamber Malpighian tubule,terminal Malpighian tubule,and the other four regions between the aforementioned two regions（four diagrams are provided for the partition of the Malpighian tubules in Cicadomorpha adults;3）the differentiation and similarities among legs,alimentary canals and Malpighian tubules within different taxa of Cicadomorpha adults and the association between these organs and their related functions not only provide support proofs and identification characteristics to monophyletic of each group in Cicadomorpha,but also provide meaningful implication and proofs of morphology,ethology,ecology and biology to the phylogeny of Cicadomorpha,i.e.,Cicadoidea is the sister group to Cercopoidea due to their certain structural and functional similarities,especially displayed by their Malpighian tubules and alimentary canals,which is closely related to the distinct cryptobiotic life modes of their immatures.
