Figure 3 in The bumblebees of the subgenus Subterraneobombus: integrating evidence from morphology and DNA barcodes (Hymenoptera, Apidae, Bombus)

Figure 3. Estimate of phylogeny for all 11 Subterraneobombus species by Bayesian analysis of a single consensus CO1 barcode sequence for each species (derived from the sequences in Figure 2), from a consensus of 18 002 sample trees after burn-in. The out-group (Bombus haemorrhoidalis, not shown) was chosen using the results of Cameron et al. (2007). Values next to the nodes are Bayesian posterior probabilities (see Fig. 2). The scale bar represents 0.02 expected substitutions per nucleotide site.
