The complete mitochondrial genome of Cryptolestes ferrugineus (Stephens) (Coleoptera: Laemophloeidae)

Abstract

We determined the complete mitochondrial genome (mitogenome) sequence of Cryptolestes ferrugineus (GenBank accession number KT182067) by the long PCR and primer walking method. The mitochondrial genome is a typical circular DNA molecule of 15 511 bp in length, and contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a A + T-rich region (D-loop). The order of 37 genes was typical of insect mitochondrial DNA sequences described to date. The base composition of the genome is A (39.17%), T (37.24%), C (14.22%), and G (9.37%) with an A + T-rich hallmark as that of other invertebrate mitochondrial genomes. All protein-coding genes start with ATN codon and terminate with the stop codon T (AA) or TAG. The A + T-rich region is located between 12S rRNA and tRNA^Ile. In this study, the phylogenetic relationships of Coleoptera species were constructed based on the nucleotides sequences of 13 PCGs of mitogenomes. The molecular-based phylogeny supported the traditional morphological classification on relationships within Coleoptera species.
