The complete mitochondrial genome of Coptotermes testaceus (Isoptera: Rhinotermitidae)

The complete circular mitochondrial genome (mitogenome) of Coptotermes testaceus is 15 752bp in size, containing 37 typical genes and one non-coding AT-rich region. The AT content of the AT-rich region is 68.3%. All protein coding genes (PCGs) start with standard ATN initiation codons and end with complete termination codons TAA or TAG except for cox2, atp8, and nad5 genes using an incomplete stop codon T. tRNA genes are predicted with a characteristic cloverleaf secondary structure except for trnS1(()(AGN)()), whose dihydrouridine (DHU) arm is replaced by a simple loop. The size of the large and small ribosomal RNA genes are 1315 and 818 bp, respectively. Phylogenetic analysis found that (i) the C. testaceus clade formed the sister group with another clade containing Coptotermes lacteus and Coptotermes formosanus; and (ii) Coptotermes lacteus had a close relationship with Coptotermes clade, but with lower credibility than other clades, the bootstrap value was 97%.
