| Summary: | Figure 5. Estimate of the phylogenetic tree for the species of the subgenus Alpinobombus (Table 1), from a linked-tree BEAST analysis of COI sequences and PEPCK exon and intron sequences for each species (Williams et al. 2015), showing the relationships of Bombus kluanensis sp. nov. Values above the nodes are Bayesian posterior probabilities showing branch support. Values below the nodes are estimated dates of divergence in Ma (millions of years before the present) calibrated from a molecular estimate for the date of divergence between the subgenus Alpinobombus and the subgenus Bombus s. str. (Hines 2008). Grey bars show the 95% confidence limits on the estimated dates of divergence.
