The complete mitochondrial genome of Ostrinia palustralis memnialis Walker, 1859 (Lepidoptera: Crambidae) was determined to be 15,246 bp with a typical set of genes (13 protein-coding genes [PCGs], 2 rRNA genes, and 22 tRNA genes) and one non-coding region, with an arrangement identical to that observed in most lepidopteran genomes. The A+T content of the whole genome, PCGs, srRNA, lrRNA, tRNAs, and the A + T-rich region all are well within the range found in other Pyraloidea. Phylogenetic analyses of the concatenated sequences of the 13 PCGs using Bayesian inference and Maximum-likelihood methods placed O. palustralis as a sister group to O. furnacalis and O. nubilalis, with the highest nodal support. The subfamilies within Crambidae, such as Nymphulinae, Spilomelinae, and Pyraustinae, all formed monophyletic groups with the highest nodal support.
