研究背景石蝇类化石记录较为完整，在中生代有三个主要类群的茎组，即舌类（toperlaria）、真颚类（Euholognatha）和系统颚类（Systemellognatha）及其部分科。然而，家庭Pteronarcyidae（鲑科，包括两个属，PteronarcysandPteronarcella）至今没有化石记录，和家庭已被建议有分歧recents.ResultsIn本文中，我们报告的一组标本属于一个新的化石种石，发现中侏罗世道虎沟地方（中国）。通过对该新种的翅脉和身体特征的比较分析，认为该新种属于翼科，与翼的亲缘关系较近。然而，它不同于前属的所有已知物种。因此，将其归为一新属，命名为中华翼麦冬（Pteroliriopesinitshenkovaegen）。et sp. nov.的分类地位。还采用了分支型命名程序，由此产生的组合Pteroliriope nec Pteronarcys sinitshenkovaesp。11月结论Pteronarcyidae化石成员的首次发现表明，相应的血统不是一个非常近期的分支，但已经存在约。一亿六千五百万年前。这一发现与大多数石煤科的分歧发生在很早的时候，可能在三叠纪，甚至在二叠纪的观点一致。这一贡献表明，需要（重新）调查化石石蝇的系统学，以完善分歧日期估计Plecoptera谱系。
BackgroundThe fossil record of Plecoptera (stoneflies) is considered relatively complete, with stem-groups of each of the three major lineages, viz. Antarctoperlaria, Euholognatha and Systellognatha (and some of their families) represented in the Mesozoic. However, the family Pteronarcyidae (the salmonflies; including two genera,PteronarcysandPteronarcella) has no fossil record to date, and the family has been suggested to have diverged recently.ResultsIn this paper, we report on a set of specimens belonging to a new fossil species of stonefly, discovered from the Middle Jurassic Daohugou locality (China). Our comparative analysis of wing venation and body characters demonstrates that the new species belongs to the Pteronarcyidae, and is more closely related toPteronarcysthan toPteronarcella. However, it differs from all known species of the former genus. It is therefore assigned to a new genus and namedPteroliriope sinitshenkovaegen. et sp. nov.under the traditional nomenclatural procedure. The cladotypic nomenclatural procedure is also employed, with the resulting combinationPteroliriope nec Pteronarcys sinitshenkovaesp. nov.ConclusionsThe first discovery of a fossil member of the Pteronarcyidae demonstrates that the corresponding lineage is not a very recent offshoot but was already present ca. 165 million years ago. This discovery concurs with the view that divergence of most stonefly families took place very early, probably in the Triassic, or even in the Permian. This contribution demonstrates the need for (re-)investigations of the systematics of fossil stoneflies to refine divergence date estimates for Plecoptera lineages.
