Data from: Genome-wide markers test the status of two putative species of North American bumble bees

Accurate species delimitation is critical to identifying the conservation
status of species. Molecular species delimitation methods have revealed
previously unrecognized cryptic species across the taxonomic spectrum.
However, studies vary in the molecular markers selected, analytical
approaches used, and taxon sampling, which sometimes results in
conflicting conclusions. We tested a two-species hypothesis of
the Bombus occidentalis complex using nuclear (ultraconserved elements,
UCE) and mitochondrial (cytochrome c oxidase I, COI) markers to infer
maximum likelihood and Bayesian phylogenies for the taxa. We extracted
tissue and sequenced 102 specimens from across the geographic range of the
species complex. Through our analyses, we concluded that the complex
actually represents two species, B. occidentalis and B.
mckayi. Here, we include the raw sequences for the UCE and COI
analyses and the final newick-formatted trees from the analyses.
