The complete mitochondria genome of Chrysomya pinguis (Diptera: Calliphoridae)

Abstract

Chrysomya pinguis (Ch. pinguis) belongs to blowfly species of great medical and forensic importance. In this study, we report the complete mitochondrial genome of the Ch. pinguis for species identification. The 38 genes presented in the 15,838 bp circular genome has been found in a typical Metazoan genome, of which there are 23 transfer RNA genes, 13 protein-coding genes and 2 ribosomal RNA genes. In addition, there is a non-coding A + T-rich region between one and another tRNA-Ile. The array of the genes is similar to that discovered in other insects. The overall base compositions of A, G, C and T are 38.72%, 9.86%, 14.07% and 37.35% respectively. This study contributes to the availability of dipteran mitochondrial genomes and provides the first complete mitochondrial genome of Ch. pinguis for entomologists to identify diagnostic regions for species identifications and phylogenetic analysis.
