Maximum likelihood (IQ-TREE) phylogeny of the subgenus Alpinobombus based on the COI gene haplotypes. The red asterisks indicate the putative species-level clades supported by mPTP species-delimitation model. The black numbers near nodes are ultrafast bootstrap support values. The haplotypes from Novaya Zemlya are colored red. The Bombus hyperboreus species complex with two valid species is colored light blue. Outgroup is not shown.
