The first complete mitochondrial genome of Dermestes dimidiatus ab. rosea Kusnezova and its phylogenetic implications for the superfamily Bostrichoidea.

In this study, the complete mitochondrial genome of Dermestes dimidiatus ab. rosea was characterized using next-generation sequencing, and the phylogenetic relationships of superfamily Bostrichoidea were established. The results showed that the mitochondrial genome of D. dimidiatus ab. rosea was 16,073 bp in size, and it contained thirteen protein-coding genes (PCGs), twenty-two transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and a control region. The composition of the whole mitochondrial genome of this species was 41.3% A, 13.5% C, 9.3% G, and 35.9% T, which had high A + T content (77.2%). Phylogenetic relationships of the superfamily Bostrichoidea showed that D. dimidiatus ab. rosea and Dermestes tessellatocollis formed in a clade that was a sister group to (Dermestes maculatus + Dermestes frischii), indicating that Dermestidae was a monophyletic group. This is the first report of a complete mitochondrial genome of D. dimidiatus ab. rosea and preliminary study of Bostrichoidea mitochondrial genome, which is of great significance for the molecular identification of this species and the enrichment of mitochondrial genome database.
