蜻蜓和豆娘是一种有魅力的中型昆虫目（类似于6300种），具有独特的潜力来解决比较研究问题。它们的分类和许多现存物种的生态特征相对较好地理解。然而，到目前为止，由于缺乏基于高通量数据的大规模系统发育，无法将这两种观点联系起来，因此无法对这些昆虫进行比较进化问题。在这里，我们提供了一个有序的分类假设的基础上锚定的杂交富集，共使用136种代表48个家庭或不确定性，共478个目标位点。我们的分析恢复了所有三个亚目：异翅目，异翅目和Zygoptera的单系。虽然拓扑结构的主干得到了加强，并显示出迄今为止最高的支持值，但我们的基因组数据无法有力地解析拓扑结构的部分。此外，四重抽样方法强调了可能影响进化系统发育的潜在进化场景（例如，最后，根据我们的基因组重建和以前的形态和分子信息，我们提出了一个更新的牙形动物分类，并定义了五个新的科（Amanipodagrionidae fam.十一月，细鳞鱼科十一月，中足齿鲨科十一月，普利斯卡格里奥科十一月，原石蛾科（1999年11月）并恢复另外两个（Rhipidolestidae stat. res.，刺甲科res.）。此外，我们的功能有问题的分类分组检查在未来的研究，以改善我们目前的系统发育假说。
Dragonflies and damselflies are a charismatic, medium-sized insect order (similar to 6300 species) with a unique potential to approach comparative research questions. Their taxonomy and many ecological traits for a large fraction of extant species are relatively well understood. However, until now, the lack of a large-scale phylogeny based on high throughput data with the potential to connect both perspectives has precluded comparative evolutionary questions for these insects. Here, we provide an ordinal hypothesis of classification based on anchored hybrid enrichment using a total of 136 species representing 46 of the 48 families or incertae sedis, and a total of 478 target loci. Our analyses recovered the monophyly for all three suborders: Anisoptera, Anisozygoptera and Zygoptera. Although the backbone of the topology was reinforced and showed the highest support values to date, our genomic data was unable to stronglyresolve portions of the topology. In addition, a quartet sampling approach highlights the potential evolutionary scenarios that may have shaped evolutionary phylogeny (e.g., incomplete lineage sorting and introgression) of this taxon. Finally, in light of our phylogenomic reconstruction and previous morphological and molecular information we proposed an updated odonate classification and define five new families (Amanipodagrionidae fam. nov., Mesagrionidae fam. nov., Mesopodagrionidae fam. nov., Priscagrionidae fam. nov., Protolestidae fam. nov.) and reinstate another two (Rhipidolestidae stat. res., Tatocnemididae stat. res.). Additionally, we feature the problematic taxonomic groupings for examination in future studies to improve our current phylogenetic hypothesis.
