To reconstruct the first nearly complete species-level molecular phylogeny of bumble bees to resolve evolutionary relationships across diverse habitats.
Sampled most of the 250 known bumble bee species representing 38 currently recognized subgenera.
Sequenced five genetic markers comprising four nuclear genes (opsin, EF-1α, arginine kinase, PEPCK) and one mitochondrial gene (16S).
Inferred tree topology and branch support using Bayesian phylogenetic analysis.
Generated a strongly supported, highly resolved phylogeny confirming the monophyly of most conventional morphology-based subgenera.
Identified two primary clades, termed short-faced and long-faced, broadly corresponding to differences in head structure.
Resolved a diverse New World radiation within the short-faced clade that encompasses nearly 25% of recognized subgenera, primarily in high-elevation Central and South American habitats.
