Figure 5 in The bumblebees of the subgenus Subterraneobombus: integrating evidence from morphology and DNA barcodes (Hymenoptera, Apidae, Bombus)

Figure 5. Estimate of phylogeny for all 11 Subterraneobombus species by Bayesian analysis of the total evidence of 658 CO1 nucleotides (Fig. 2), reduced to a single consensus sequence for each species, in combination with the 27 morphological characters for the species (Fig. 4), 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 changes per nucleotide site or character.
