The cleptoparasitic bee genus Nomada (Hymenoptera: Apidae) is the most diverse lineage of cleptoparasitic bees. Previous studies not only validated 13 of the 16 species groups originally proposed but found additional species groups while also resurrecting and creating multiple subgenera. Although, the global biogeography for the genus was inferred once before, with the addition of new species groups across the Palearctic and new information pertaining to the origin and evolution of bees, a new global biogeography for Nomada is needed. Using molecular techniques, we expand on our previous work to 1) include 64 newly sequenced species and 2) update the current biogeography of the genus. Ultra-conserved elements (UCEs) are used to construct a phylogenetic tree showing the relationships between the included 230 species and all current species groups as well as inform and update our original biogeographical analyses. Here we present the most comprehensive molecular phylogeny and historical biogeography for Nomada across their global range. These results provide an important and invaluable foundation for understanding their evolution and diversification.
