Zoraptera的地位仍然是昆虫的普通水平的生殖学中最具挑战性和不确定性的问题之一。Zoraptera被认为与Polyneoptera的五个不同类群有着密切的关系，或者与Paraneoptera甚至Holometabola有亲缘关系。尽管rDNA已广泛应用于昆虫系统发育研究，但完整的28 S rDNA的应用仍然分散在少数目中。本研究以昆虫纲各目昆虫为研究对象，构建了昆虫28 SrRNA完整序列的二级结构模型。发现一个长度可变区D3-4特别独特。D3-4的长度和/或序列在Polyneoptera的每个目中是保守的，但它可以在超群的不同目之间分为两种类型，其中神秘的Zoraptera和Dictyoptera共享一种类型，而Polyneoptera的其余目共享另一种类型。此外，独立的证据系统发育的结果支持分支（Zoraptera+网翅目）以及。因此，D3-4在Zoraptera和网翅目之间的相似性可以作为潜在的有价值的自态性或共态性在系统发育重建。在系统发育研究中，还恢复了（Plecoptera+Dermaptera）和（（Grylloblattodea+Mantophasmatodea）+（Embiodea+Phasmatodea））两个分支。此外，与其他基于rDNAs的研究相比，本研究与以往基于核蛋白编码基因或形态学特征的全代谢菌系统发育研究的一致性最高。未来的二级结构的比较研究，在深分歧和额外的类群可能会揭示保守的模式，结构和图案，可以提供支持的主要系统发育谱系。
The position of the Zoraptera remains one of the most challenging and uncertain concerns in ordinal-level phylogenies of the insects. Zoraptera have been viewed as having a close relationship with five different groups of Polyneoptera, or as being allied to the Paraneoptera or even Holometabola. Although rDNAs have been widely used in phylogenetic studies of insects, the application of the complete 28S rDNA are still scattered in only a few orders. In this study, a secondary structure model of the complete 28S rRNAs of insects was reconstructed based on all orders of Insecta. It was found that one length-variable region, D3-4, is particularly distinctive. The length and/or sequence of D3-4 is conservative within each order of Polyneoptera, but it can be divided into two types between the different orders of the supercohort, of which the enigmatic order Zoraptera and Dictyoptera share one type, while the remaining orders of Polyneoptera share the other. Additionally, independent evidence from phylogenetic results support the clade (Zoraptera+Dictyoptera) as well. Thus, the similarity of D3-4 between Zoraptera and Dictyoptera can serve as potentially valuable autapomorphy or synapomorphy in phylogeny reconstruction. The clades of (Plecoptera+Dermaptera) and ((Grylloblattodea+Mantophasmatodea)+(Embiodea+Phasmatodea)) were also recovered in the phylogenetic study. In addition, considering the other studies based on rDNAs, this study reached the highest congruence with previous phylogenetic studies of Holometabola based on nuclear protein coding genes or morphology characters. Future comparative studies of secondary structures across deep divergences and additional taxa are likely to reveal conserved patterns, structures and motifs that can provide support for major phylogenetic lineages.
