摘要

本研究总结了对骆驼蜘蛛属 Chanbria Muma（1951 年）的分类学处理。本研究采用综合分类方法，结合系统发生组、形态学和地理信息，对该属进行了修订。在目前归入该属的四个物种中，保留了两个：Chanbria regalis Muma, 1951 和 Chanbria serpentinus Muma, 1951。Eremochelis plicatus（Muma，1962 年）被转入该属，因为根据使用从超保留元素数据中恢复的数百个位点进行的几次系统发生分析，它与 Chanbria 始终处于一个支系中。在本研究中，我们重新分析了以前获得的基因组数据，以评估以前的物种假说，并确定了支持 Chanbria 单系的新的形态异构体。基因数据支持 Chanbria rectus Muma, 1962 与 C. regalis 的同名异名。此外，我们将Chanbria tehachapianus Muma, 1962与C. regalis同名，因为C. tehachapianus是根据有限的形态学信息和C. regalis其他种群之间缺乏地理分隔而建立的。描述了两个新种：Chanbria brookharti sp.这使得已描述的 Chanbria 物种总数达到五个公认的物种：C. regalis、C. serpentinus、C. plicatus com.nov.、C. brookharti sp.nov.和C. mapemes sp.nov.。

A phylogenomic approach to a taxonomic revision: a combination, new synonymies, and a description of two new species within the camel spider genus Chanbria Muma, 1951 (Solifugae: Eremobatidae)

This study summarizes the taxonomic treatment of the camel spider genus Chanbria Muma, 1951. Taking an integrative taxonomic approach incorporating phylogenomic, morphological, and geographical information, the genus is herein revised. Of the four species currently placed in the genus, two are retained: Chanbria regalis Muma, 1951 and Chanbria serpentinus Muma, 1951. Eremochelis plicatus (Muma, 1962) is transferred to this genus because it is consistently recovered in a clade with Chanbria based on several phylogenetic analyses using hundreds of loci recovered from ultraconserved element data. In this study, we re-analyse previously acquired genomic data to assess former species hypotheses and identify new morphological synapomorphies that support the monophyly of Chanbria. The genetic data support the synonymization of Chanbria rectus Muma, 1962 syn. nov. with C. regalis. Furthermore, we synonymize Chanbria tehachapianus Muma, 1962 syn. nov. with C. regalis because C. tehachapianus was erected based on limited morphological information and lack of geographical separation between other populations of C. regalis. Two new species, Chanbria brookharti sp. nov. and Chanbria mapemes sp. nov., are described. This brings the total number of species of Chanbria described to five recognized species: C. regalis, C. serpentinus, C. plicatus com. nov., C. brookharti sp. nov., and C. mapemes sp. nov.

期刊介绍： The Zoological Journal of the Linnean Society publishes papers on systematic and evolutionary zoology and comparative, functional and other studies where relevant to these areas. Studies of extinct as well as living animals are included. Reviews are also published; these may be invited by the Editorial Board, but uninvited reviews may also be considered. The Zoological Journal also has a wide circulation amongst zoologists and although narrowly specialized papers are not excluded, potential authors should bear that readership in mind.
