耳蝠是一种物种相对贫乏的昆虫目。虽然这一谱系的生殖发育的各个方面知之甚少，在本研究之前，有一个普遍的共识，即Dermaptera包括两个主要的谱系：并系的Protodermaptera或“较低的earwigs”和单系的Epidermaptera或“较高的earwigs”，这是嵌套在前者。我们基于对3247个核单拷贝基因的分析的基因组学研究通过将单系原皮目置于并系Epidermaptera内来逆转这些关系。这种主要的土拨鼠谱系之间的系统发育逆转并不与形态学上的争论相矛盾，但却导致了对皮翅目地面计划的深远的重新解释。在Dermaptera，Apachyidae形成姐妹组，其余的earwigs这可能意味着社会行为不是earwig地面计划的一部分。我们的研究结果证实了Eudermaptera单系内Epidermaptera和几个传统的家庭的并系。原皮目的单系性得到了分子和形态学证据的支持，尽管没有被包括在分子数据集中的Karamellidae的确切位置无法确定。
Earwigs are one of the comparatively species‐poor insect orders. Although various aspects of the phylogeny of this lineage are poorly understood, before the present study, there was a general consensus that Dermaptera comprises two major lineages: the paraphyletic Protodermaptera or ‘lower earwigs’ and the monophyletic Epidermaptera or ‘higher earwigs’, which are nested within the former. Our phylogenomic study based on the analysis of 3247 nuclear single‐copy genes reverses these relationships by placing monophyletic Protodermaptera within paraphyletic Epidermaptera. This phylogenetic reversal among the major earwig lineages is not contradicted by morphological arguments but results in far‐reaching reinterpretations of the dermapteran ground plan. Within Dermaptera, Apachyidae form the sister group to the remaining earwigs which might imply that social behaviour is not part of the earwig ground plan. Our results corroborate the monophyly of Eudermaptera within Epidermaptera and the paraphyly of several traditional families. The monophyly of Protodermaptera is supported by molecular and morphological evidence, although the exact position of Karschiellidae which were not included in the molecular dataset cannot be determined.
