Abstract
The complete mitochondrial genome of the Colletes gigas (Hymenoptera: Colletidae) is determined to be 15,885 bp in length, containing 37 typical animal mitochondrial genes: 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a major non-coding AT-rich region. All PCGs initiate with typical ATN codons and end with the complete termination codon TAA, except for the cob gene, which harbors the stop codon of TAG. Twenty-four intergenic spacers (614 bp in total) and 7 overlapping regions (37 bp in total) are dispersed throughout the whole genome. The non-coding AT-rich region is 539 bp long and contains a tandem repeat region, which has also been reported in other insects. This is the first completely sequenced mitochondrial genome of the family Colletidae.
