First complete mitochondrial genome sequence from the tribelocephaline assassin bugs (Hemiptera: Reduviidae).

The complete mitochondrial genome (mitogenome) of Opistoplatys sp. was determined, which was the first representation from the assassin bug subfamily Tribelocephalinae. The mitogenome is a typical circular DNA molecule of 15,615 bp and contains 37 genes and a putative control region. All the 13 protein-coding genes initiate with ATN codons and mostly terminate with TAA or TAG codons except for COII, COIII, and ND5 genes use a single T residue as the termination codon. All the 22 tRNAs have the clover-leaf structure except for the tRNASer(AGN) with the length ranging from 60 to 72 bp. The control region is 1068 bp in length and includes 456 bp tandem repeat sequence with four 94-bp tandem repeat units and a partial fifth (80 bp). In the sampled subfamilies of Reduviidae, Peiratinae + the remaining subfamilies, Triatominae + Stenopodainae, Tribelocephalinae + Ectrichodiinae, are recovered in phylogenetic analyses with high supports.
