Complete mitochondrial genome of Bombus waltoni (Hymenoptera: Apidae)

The complete mitochondrial genome of Bombus (Mendacibombus) waltoni was sequenced. The circle genome of the bee is 19,349 bp in length. There are 38 sequence elements including 13 protein coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. The order of most elements was consistent with that of other bumblebee species that have been previously described, with the exception of five tRNA genes in two segments. The use of B. waltoni mitogenome as an outgroup significantly improved the robustness of phylogenetic reconstruction for bumblebees.
