摘要昆虫的翅膀是其最显著的特征之一，体现了许多与其生活方式的多样性相一致的特征和修饰。然而，尽管它们与进化相关，但翅膀结构的同源陈述和命名仍然研究不足，有时甚至令人困惑。早期关于翅膀脉序同源性的研究经常假设翼翅目(包括直翅目、大翅目和脉翅目：蛇、苍蝇和斑翅亚目)在翼形目中是古老的，因此依赖于它们的脉序模式来确定昆虫翅膀脉序模式，这些假设相互影响着对割翼的解释。然而，神经翅目实际上起源于飞行的昆虫，因此重新考虑它们的翅膀是至关重要的。由于融合和丢失，鉴定神经翼目的实际翼脉变得困难，但这些特征为该类群内不同支系的分类提供了系统和分类信息。在本研究中，我们回顾了关于翼脉在神经翼目之间的同源性声明，重点是叶蜂科(绿叶草科)，其中静脉融合程度最高的家族是明显的。每目的翼脉按管状排列进行了回顾，并提供了实际翼脉的彩色图解以及选定科中管状脉序的详细说明。根据我们对静脉气管形成的研究结果，提出了新的同源陈述和静脉和细胞的修订命名法。
ABSTRACT The wings of insects are one of their most prominent features and embody numerous characters and modifications congruent with the variety of their lifestyles. However, despite their evolutionary relevance, homology statements and nomenclature of wing structures remain understudied and sometimes confusing. Early studies on wing venation homologies often assumed Neuropterida (the superorder comprising the orders Raphidioptera, Megaloptera, and Neuroptera: snakeflies, alderflies and dobsonflies, and lacewings) to be ancient among Pterygota, and therefore relied on their pattern of venation for determining groundplans for insect wing venation schemata and those assumptions reciprocally influenced the interpretation of lacewing wings. However, Neuropterida are in fact derived among flying insects and thus a reconsideration of their wings is crucial. The identification of the actual wing venation of Neuropterida is rendered difficult by fusions and losses, but these features provide systematic and taxonomically informative characters for the classification of the different clades within the group. In the present study, we review the homology statements of wing venation among Neuropterida, with an emphasis on Chrysopidae (green lacewings), the family in which the highest degree of vein fusion is manifest. The wing venation of each order is reviewed according to tracheation, and colored schemata of the actual wing venation are provided as well as detailed illustrations of the tracheation in select families. According to the results of our study of vein tracheation, new homology statements and a revised nomenclature for veins and cells are proposed.
