Figure 5. Bayesian estimate of phylogeny from COI barcodes for all of the recently accepted species of the subgenus Melanobombus worldwide (excluding B. rufipes) and (in grey) selected outgroups. Values next to nodes are Bayesian posterior probabilities showing branch support from the BEAST analysis from 100 million MCMC generations with a 1% burn-in. Sample labels show sequence length, taxon name, sequence number from GenBank or BOLD, the country and (for larger countries) province from which each sample originated.
