title: The complete mitochondrial genome of Dixella sp. (Diptera: Nematocera, Dixidae).
abstract: In the present paper, the first complete mitochondrial genome of the family Dixidae is reported. The complete mitochondrial genome of Dixella sp. is a circular molecule of 15,574 bp in length, containing all 37 genes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (srRNA and lrRNA), and a long control region. Its gene arrangement is conserved with the ancestral gene order of Drosophila yakuba, which is considered to exhibit the ground pattern of Hexapoda mitochondrial genome. Most PCGs start with standard ATN codons, while COI uses CCG, ND1 uses TTG and ND5 uses GTG as start codons. All PCGs terminate in the common stop codons TAA, except for COII and ND5 which end with a single thymine stop codon. There is a 703 bp of the control region, located between srRNA and tRNA(lle)-tRNA(Gln)-tRNA(Met) (IQM) cluster, without conserved blocks or long tandem repeats.
