摘　　要：从捻翅目的基本特征、分类地位、起源和高级阶元的系统演化关系等 4个方面对捻翅目的系统演化关系进行了探讨。目前关于捻翅目的分类地位主要包括以下观点 :1)是其他内生翅类的姐妹群 ;2 )是鞘翅目大花蚤科的姐妹群 ;3 )是鞘翅目的姐妹群 ;4)是双翅目的姐妹群。通过讨论 ,初步认为鞘翅目与捻翅目不是姐妹群 。This paper mainly discusses the phylogeny of the Strepsiptera including, the taxonomic characteristics, phylogenetic placement, origin and phylogeny of this family. The Strepsiptera are obligate parasites of other insects, with a range of hosts from 7 orders and 34 families. They are an odd group of insects whose phylogenetic relationships have long been a mystery. Females are wingless, and in all families, except the Mengenillidae, are highly modified and reduced, without appendages, never leaving the host. Males have many derived features as well, including reduced forewings, fan-shaped hindwings, antennae with processes, and unusual raspberry-like eyes. In recent years, four phylogenetic placements of the Strepsiptera have been discussed: 1) Sister group to the Endopterygota;2)Sister group to the Rhipiphoridae;3)Sister group to the Coleoptera; 4) Sister group to the Diptera. Though the taxonomic position of the Strepsiptera is still not resolved, molecular and morphological research currently in progress should clarify the position of this group. The oldest Strepsipteran fossil is a first instar larval Stichotrema eocaenicum (Haupt, 1950) from the Eocene period found in Germany. After Kinzelbach's research, most living genera were probably extant through most of the Tertiary. According to Kathinthamby's hypotheses, the Myrmecolacidae may have appeared in the late Cretaceous, and the Halictophagidae, Elenchidae, Corixenidae and Mengenillidae perhaps had an origin in the Jurassic. However, if the Coleoptera are indeed the sister group of the Strepsiptera, this suggests an even older origin. Coleopteran fossils extend to the Permian, and, based on sister-group dating, the Strepsiptera should also be expected to be this old, however, the oldest Strepsipteran fossil is from Eocene. Consequently, a sister-group relationship with the Coleoptera is unlikely in the absence of further evidence. The Strepsiptera is divided into two suborders (Mengeillidia and Stylopidia) and nine families. The monophyly of the Stylopid
