With about 1700 described species, the mining bee genus is a rapidly diversifying lineage and one of the most species-rich groups of bees. Recent phylogenomic advances have greatly improved our understanding of the phylogeny of the genus, yet many species still await description, subgeneric assignments that are in line with their evolutionary history, as well as study of their morphology and behavior. Here we provide a comprehensive account of a newly discovered species, n. sp. We sequence the genome of the new species and include it in the presently most comprehensive phylogenomic analysis of using ultraconserved element (UCE) sequence data, comprising 264 samples and 249 species. Given the recovered phylogenetic position of the new species, we establish a new subgenus, , provide a detailed morphological description, and discuss the antiquity and historical biogeography of the lineage in light of molecular divergence time estimates. Lastly, we study and document the foraging behavior of the new species with photos and video footage, and discuss the species' unusual host plant associations with and , both Solanaceae. Being likely oligolectic on these plants, we present the first documented case of an species being narrowly associated with members of this plant family. By integrating multiple lines of documentation, our study provides a particularly detailed account of species discovery and description.
掘土蜂属约有1700种已被描述的物种，是一个快速多样化的谱系，也是蜜蜂中物种最丰富的类群之一。最近的系统基因组学进展极大地增进了我们对该属系统发育的理解，但仍有许多物种有待描述、有待进行与其进化历史相符的亚属分类，以及有待对其形态和行为进行研究。在此，我们全面介绍一个新发现的物种，[新物种名称]。我们对该新物种的基因组进行了测序，并将其纳入目前使用超保守元件（UCE）序列数据对[属名]进行的最全面的系统基因组分析中，该分析包含264个样本和249个物种。鉴于新物种在系统发育中的位置，我们建立了一个新的亚属，[亚属名称]，提供了详细的形态描述，并根据分子分歧时间估计讨论了该谱系的古老性和历史生物地理学。最后，我们用照片和视频记录了新物种的觅食行为，并讨论了该物种与茄科的[寄主植物1名称]和[寄主植物2名称]的不同寻常的寄主植物关联。由于该物种可能对这些植物具有寡食性，我们展示了第一个有记录的掘土蜂物种与该植物科成员紧密关联的案例。通过整合多条记录线索，我们的研究对物种发现和描述进行了特别详细的阐述。
