| 摘 要： | 应用支序系统学原理，选用PHYLIP和HENNIG86系统发育分析计算机程序，初步分析了“广腰亚目”的系统发育．支序分析结果表明：①原广胸亚目是一并系群，无共近裔性状；②原Tenthredinoidea，Mesalodontoidea两个总科成立，均为单系群；③Orussidae归入Siricomornha更为合适，虽然Orussidae也有一定的可能性是Anocrita的姐妹群；④Cenhidae最可能是Apocrita的姐妹群；⑤原Xyelinae,Macroxvelinae组成的Xyelidae很可能是并系群，但这个类群具有不为其他类群所共有的近商共性（触角第3节长棒状，由多节愈合而成，并具1多节的端丝），似应暂时保留为一个总科类群；⑥Blasticotomidae与原广腰亚目的其他类群关系较远，归入原Tenthredinoidea原Siricoidea均不合适．据此建立一个初步的新分类系统：原广腰亚目划分为5亚目11总科。建立一个新的四节叶蜂亚目Blasticotomorpha;原长节叶蜂科分裂为2科；尾蜂总科划归树蜂亚目；原叶蜂总科所辖的5个科提升为叶蜂亚目的5个总科．

| Abstract: | The Phylogeny of Symphyta has been studied by using phylogenetic programs HENNIG86 and PHYLIP based on the principle and methods of Cladistics. The main results are as follows: 1. Since Symphyta has no synapomorphy, it is a paraphyletic taxon; 2. Tenthredinoidea and Megalodontoidea are surely monophyletic taxa; 3. It is more suitable for Orussidae to fall into Siricomorpha than to erect an isolated orussomorpha. Orussoidea is a somewhat remote evolutionary clad of siricomorpha but it is distinctly allied to Siricoidea; 4.Cephidae is much probably the sister group of Apocrita; 5. Xyelidae is a paraphyletic taxon; 6. Blasticotomidae is far remote from other taxa of Symphyta though it may be the sisrergroup of Siricomorpha Cephomorpha Apocrita. Based on the Cladistic analysis of Symphyta, a new system has been proposed in this paper. |
