中华足纲蜘蛛是一个多样化的群体，分散能力有限。它们在相关物种中具有显着的同域性，这常常导致错误识别和不正确的性别匹配。为了了解该属的进化关系并修正分类问题，我们提供了第一个中华足类的分子系统发育。我们的结果强烈支持中华足纲的单系性及其与 Spariolenus 的姐妹关系，并拒绝冲绳 S. okinawana 物种组的单系性。我们根据分子和形态学数据建立了三个新物种组。我们的系统发育还阐明了一些分类学问题并澄清了一些物种限制：（1）支持Zhong等人新修订的S. longiducta和S. yaanensis的性别匹配。 （2019）。 (2) 对风铃草的最初描述是基于性别不匹配。 S. changde 被提议作为 S. Campanacea 的初级异名，而原始的雌性 S. changde风铃草在这里被描述为一个新物种：S. papilionaceous Liu sp.。十一月(3) S. serpentembolus 模式系列存在性别不匹配。雌性被认为是 S. Campanacea，而我们在这里报告了正确匹配的雌性 S. serpentembolus。 (4)我们描述了另外一个新种：S. wuyiensis Liu sp。十一月我们对中华足纲的第一个分子系统发育提供了比较分析的工具，并为该属未来的生物多样性和分类学工作奠定了坚实的基础。
Sinopoda spiders are a diverse group with limited dispersal ability. They are remarkably sympatric among related species, which often results in misidentification and incorrect matching of sexes. In order to understand the evolutionary relationships and revise the taxonomy problems in this genus, we offer the first molecular phylogeny of Sinopoda. Our results strongly support the monophyly of Sinopoda and its sister relationship with Spariolenus and reject the monophyly of the S. okinawana species group. We establish three new species groups based on both molecular and morphological data. Our phylogeny also illuminates some taxonomic issues and clarifies some species limits: (1) Supporting the newly revised matching of sexes in S. longiducta and S. yaanensis by Zhong et al. (2019). (2) The original description of S. campanacea was based on mismatched sexes. S. changde is proposed as a junior synonymy of S. campanacea, while the original female ‘S. campanacea’ is here described as a new species: S. papilionaceous Liu sp. nov. (3) The type series of S. serpentembolus contains mismatched sexes. The female is considered as S. campanacea, while we here report the correctly matched females of S. serpentembolus. (4) We describe one additional new species: S. wuyiensis Liu sp. nov. Our first molecular phylogeny of Sinopoda provides a tool for comparative analyses and a solid base for the future biodiversity and taxonomic work on the genus.
