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.

分类学修订的系统发育方法：骆驼蜘蛛属 Chanbria Muma 内两个新物种的组合、新同义词和描述，1951（Solifugae：Eremobatidae）

本研究总结了骆驼蜘蛛属 Chanbria Muma, 1951 的分类学处理。采用综合分类学方法，结合系统发育、形态学和地理信息，在此对该属进行了修订。目前归入该属的四个物种中，有两个被保留：Chanbria regalis Muma, 1951 和 Chanbria serpentinus Muma, 1951。Eremochelis plicatus (Muma, 1962) 被转移到该属，因为它始终在与 Chanbria 的分支中被发现，基于使用从超保守元素数据中恢复的数百个基因座进行了一些系统发育分析。在这项研究中，我们重新分析了之前获得的基因组数据，以评估以前的物种假设，并确定支持 Chanbria 单系的新形态共性。遗传数据支持 Chanbriaectus Muma, 1962 syn 的同义。十一月与 C. regalis。此外，我们将 Chanbria tehachapianus Muma, 1962 syn 命名为同义词。十一月与 C. regalis 不同，因为 C. tehachapianus 是根据有限的形态信息而建立的，并且 C. regalis 的其他种群之间缺乏地理隔离。两个新种，Chanbria brookharti sp。十一月和 Chanbria mapemes sp。十一月，进行了描述。这使得所描述的 Chanbria 物种总数达到了五个公认物种：C. regalis、C. serpentinus、C. plicatus com。 11 月，C. brookharti sp。 11 月，和 C. mapemes sp。十一月
