The complete mitochondria genome of Aldrichina grahami (Diptera: Calliphoridae)

Aldrichina grahami is a significant medical and forensic insect belonging to the family calliphoridae. In this study, we present the complete mitochondrial genome of A. grahami for the first time. The mitogenome was 14 903 bp in length, consisting of 22 transfer RNA genes, 2 ribosomal RNA genes and 13 protein-encoding genes. The overall base compositions of A, G, C and T were 39.14, 9.59, 13.65 and 37.62%, respectively. Phylogenetic analysis is conducted using 12 mitochondrial genomes from two families. The monophyletic branches of the phylogenetic tree reveal that the composition of the mitochondrial genome, particularly the gene lengths, is very similar to that of another Calliphoridae fly, C. vicina, but the interspecific variations between them was 5.4%, which could distinguish these two species explicitly. Phylogenetic analyses indicated that phylogenetic analysis of whole mt genome sequences resulted in much stronger support for the identification of A. grahami between other species. This article aimed to enrich the dipteran mitochondrial genomes and provides the complete mitochondrial genome and phylogenetic analyses of A. grahami for species identifications forensic purpose.
