Mitochondrial genome of Hylaeus dilatatus (Hymenoptera: Colletidae).

Bees are one of the most well-known and important type of pollinators in agriculture and natural ecosystems, and maintaining their diversity in nature is essential. In this study, we report the complete mitochondrial genome of Hylaeus dilatatus, the first mitochondrial genome of Colletidae. Its complete mtDNA sequence is 15,475 bp in length, which contains 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region. The base composition of mtDNA is 44.27% A, 41.52% T, 8.80% C and 5.41% G. The percentage of A + T is 85.79%. The first complete mitogenome of Colletidae family could be used in studies of molecular systematics, conservation genetics, and stock evaluation.
