The complete mitochondrial genome analysis of Eristalis tenax (Diptera, Syrphidae).

The complete mitochondrial genome of Eristalis tenax (Linnaeus, 1758) (Diptera, Syrphidae) is reported here. This is the first sequenced mitogenome from the subfamily Milesiinae. The whole mitochondrial genome is 16,091 bp in length and contains 37 canonical genes, which include 22 transfer RNA genes, 13 protein-coding genes and two ribosomal RNA genes, the control region is 1125 bp in length. Most PCGs start with standard ATN codons, while CO1 and ND1 use TTG, CO3 uses TGG as start codons. All PCGs terminate in the common stop codons TAA. In addition, the nucleotide composition of the coding region was 40.0% of A, 40.1% of T, 11.2% of C, 8.7% of G and 80.1% of A + T content. The phylogenetic tree shows that Syrphidae is the sister group of Pipunculidae.
