The mitochondrial genome of the garden pea leafminer Chromatomyia horticola (Goureau, 1851) (Diptera: Agromyzidae).

Here we report the mitochondrial genome sequence of the garden pea leafminer Chromatomyia horticola (Goureau, 1851) (Diptera: Agromyzidae) (GenBank accession no. KR047789). This is the first species with sequenced mitochondrial genome from the genus Chromatomyia. The current length with partial A  +  T-rich region of this mitochondrial genome is 15,320 bp with an A  +  T content of 77.54%. All the 13 protein-coding, two rRNA, and 22 tRNA genes were sequenced, except for the A  +  T-rich region. As in most other sequenced mitochondrial genomes of Diptera, there is no rearrangement compared with the pupative ancestral arrangement of insects. All protein-coding genes start with the ATN start codon except for the gene cox1, which uses abnormal TTG. The A  +  T-rich region is located between rrnS and trnI with a sequenced length of 503 bp. Phylogenetic analysis using the Bayesian method based on the first and second codon positions of the 13 protein-coding genes recovered the monophyly of Agromyzidae with one species of Chromatomyia and four species of Liriomyza in our study. The superfamily Oestroidea (with Agromyzidae in analysis) is sister to the Opomyzoidea.
