The monophyly of Diplura and its phylogenetic relationship with other hexapods are important for understanding the phylogeny of Hexapoda. The complete 18SrRNAgene and partial 28SrRNA gene (D3-D5 region) from 2 dipluran species (Campodeidae and Japygidae), 2 proturan species, 3 collembolan species, and 1 locust species were sequenced. Combining related sequences in GenBank, phylogenetic trees of Hexapoda were constructed by MP method using a crustacean Artemia salina as an outgroup. The results indicated that: (i) the integrated data of 18SrDNA and 28SrDNA could provide better phylogenetic information, which well supported the monophyly of Diplura; (ii) Diplura had a close phylogenetic relationship to Protura with high bootstrap support.
双尾目的单系性及其与其他六足动物的系统发育关系对于理解六足动物的系统发育至关重要。对2种双尾目昆虫（原铗尾虫科和铗尾虫科）、2种原尾目昆虫、3种弹尾目昆虫和1种蝗虫的完整18SrRNA基因和部分28SrRNA基因（D3-D5区域）进行了测序。结合GenBank中的相关序列，以甲壳动物卤虫作为外群，采用最大简约法构建了六足动物的系统发育树。结果表明：（i）18SrDNA和28SrDNA的整合数据能提供更好的系统发育信息，有力支持了双尾目的单系性；（ii）双尾目与原尾目具有密切的系统发育关系，自展支持率很高。
