Exploring the phylogeny of the parasitic Neolarrini, with a focus on the North American Biastes (Hymenoptera: Apidae)

Recent systematic work synonymized three small tribes, Townsendellini, Neolarrini, and Biastini, into Neolarrini. Neolarrini is now a  tribe of brood parasitic bees in the subfamily Nomadinae containing 5 genera and 37 species. Within Neolarrini, the European genus Biastes and North American genus Neopasites have been synonymized into Biastes based on combined molecular and morphological work. Previous to this synonymization, Neopasites was split into two subgenera, Neopasites and Micropasites, based on number of maxillary palps and second submarginal cell size. Here, using low coverage genomes, we explore whether or not Micropasites and Neopasites are monophyletic groupings including historical specimens from regions where Neopasites was previously unknown as well as increase the sampling of Neopasites species to confirm the synonymy.
