In this study, the complete mitochondrial genome of Maruca testulalis was determined (GenBank accession number KJ623250). It is 15,110 bp in length, and included 13 PCGs, 2 rRNA gens, 22 tRNA genes, and a A + T-rich region. Its gene order and orientation are identical to other crambid species. The AT-skew and GC-skew of the entire mitogenome are negative and the nucleotide composition is biased toward A + T nucleotides (80.6%). All PCGs begin with ATN codons, except for COI which is initiated by CGA. All the 22 tRAN genes can be fold into the typical clover-leaf secondary structure except for tRNA(ser)(AGN). The 335 bp long A + T-rich region is located between srRNA and tRNA(Met) and contains some common features of the other lepidopterans, including the motif ATAGT followed by 14 bp poly-T stretches and a microsatellite-like (AT)11 elements preceded by the ATTTA motif.
