Complete mitochondrial genome of the Antarctic midge Parochlus steinenii (Diptera: Chironomidae)

Abstract

<em>Parochlus steinenii </em>is a winged midge found in the Antarctic Peninsula and its offshore islands. We determined the complete mitochondrial genome sequence of<em> P. steinenii</em>, which is comprised of 16 803 nucleotides and contains 13 protein-coding genes (PCGs), 22 tRNA genes, and the large (rrnL) and small (rrnS) rRNA genes. Its total A + T content is 72.5%. The PCG arrangement of<em> </em>P. steinenii is identical to that of the ancestral Diptera ground pattern. This is the first report on the mitogenome sequence of an Antarctic midge, and provides insights into the evolution of dipterans in Antarctica
