Complete mitochondrial genome of Bombus breviceps (Hymenoptera: Apidae).

The complete mitochondrial genome of Bombus breviceps, which belongs to the subgenus of Alpigenobombus in Bombus genus, was sequenced. This circular mitogenome is 16,743 bp (83.5% AT) in length, with two rRNA genes, 22 tRNA genes, and 13 protein-coding genes. All protein-coding genes are initiated with the common invertebrate initiation codon except TTA for ND2, and terminated by the typical stop codon TAA or TAG. tRNA-Ser (TCT) lacks a dihydrouridine (DHU) arm while other tRNA genes form a cloverleaf structure. Phylogenetic analysis shows that genus Bombus has a closer relationship with genus Melipona than any other genera in Apidae family, and B. breviceps clusters closer to B. lapidarius than any other bumblebees with sequenced mitogenome.
