Abstract

The complete mitochondrial genome (mitogenome) of the jewel beetle, Trachys variolaris, was sequenced and described. The mitogenome of T. variolaris is a typical circular DNA molecule with 16,771 bp in length. It contains the typical 37 mitochondrial genes (13 protein-coding genes, two rRNA genes, and 22 tRNA genes) and a long non-coding region called the control region. Twelve protein-coding genes initiate with ATN codons except ND1 uses TTG. Most of the protein-coding genes use TAA or TAG as the stop codon, but COII, COIII, ND4, and ND5 terminate with a single T-- or TA-. The length of the 22 tRNAs ranges from 61 to 70 bp and they all have the clover-leaf structure except for tRNA^Ser(AGN) . The control region is 2155 bp long with the A + T content of 69.4%. The result of our phylogenetic analysis showed that Buprestoidea is monophyletic, and it is the sister group to (Byrrhoidea + Elateroidea).
