Abstract

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 . Our results strongly support the monophyly of and its sister relationship with and reject the monophyly of the 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 and by Zhong et al. (2019). (2) The original description of was based on mismatched sexes. is proposed as a junior synonymy of , while the original female '' is here described as a new species: Liu (3) The type series of contains mismatched sexes. The female is considered as , while we here report the correctly matched females of . (4) We describe one additional new species: Liu Our first molecular phylogeny of provides a tool for comparative analyses and a solid base for the future biodiversity and taxonomic work on the genus.

摘要

蜘蛛是一个具有有限扩散能力的多样化群体。它们在相关物种中显著地同域分布，这常常导致错误鉴定和性别错配。为了理解该属的进化关系并修正分类学问题，我们提供了首个[该属名称]的分子系统发育研究。我们的结果有力地支持了[该属名称]的单系性及其与[另一属名称]的姐妹关系，并否定了[某物种组名称]物种组的单系性。我们基于分子和形态数据建立了三个新的物种组。我们的系统发育研究还阐明了一些分类学问题并明确了一些物种界限：（1）支持钟等人（2019年）对[物种名称1]和[物种名称2]新修订的性别匹配。（2）[物种名称3]的原始描述基于性别错配。[物种名称3]被提议作为[物种名称4]的次异名，而原始的雌性“[原雌性名称]”在此被描述为一个新物种：[新物种名称1] 刘 （3）[物种名称5]的模式系列包含性别错配。雌性被认为是[错误认定的物种名称]，而我们在此报告了[物种名称5]正确匹配的雌性。（4）我们描述了另一个新物种：[新物种名称2] 刘 我们首个[该属名称]的分子系统发育研究为比较分析提供了一个工具，并为该属未来的生物多样性和分类学工作奠定了坚实基础。
