Figs 2‒6 in The steppe bumblebees of the subgenus Sibiricobombus revised world-wide from species' gene coalescents and morphology despite numts (Hymenoptera, Apidae, genus Bombus)

Figs 2‒6. Distribution of AT3% scores from COI barcode-like sequences used for analyses of species in a selection of previous studies of bumblebee subgenera (lower AT3% is associated with numts). 2. Subterraneobombus Vogt, 1911 from Williams et al. (2011). 3. Alpinobombus Skorikov, 1914 from Williams et al. (2019). 4. Alpigenobombus Skorikov, 1914 from Williams et al. (2023). 5. Sibiricobombus Vogt, 1911 from Fig. 1. 6. The top row shows the 51 nucleotides in the primer LepF1 and the reverse complement of the primer LepR1 (primers from Hebert et al. 2004), the rows below showing the equivalent mitogenome Lep-primer-binding regions for an example species of each of the four subgenera by Illumina sequencing from Sun et al. (2020): the coloured markers (red+yellow) together highlight total nucleotide substitutions relative to the Lep primers, the red markers highlighting the numbers of substitutions of G/C for A/T or vice versa relative to the Lep primers, with the columns on the right showing (Δ) the total numbers of substitutions and (ΔGC) the numbers of substitutions of G/C for A/T or vice versa relative to the Lep primers (substitutions unique to A. breviceps + S. sibiricus are shown in bold).
