Loxostege turbidalis, Loxostege aeruginalis, Pyrausta despicata, and Crambus perlellus belong to Crambidae, Pyraloidea. Their mitochondrial genomes (mitogenomes) were successfully sequenced. The mitogenomes of L. turbidalis, L. aeruginalis, P. despicata, and C. perlellus are 15 240 bp, 15 339 bp, 15 389 bp, and 15 440 bp. The four mitogenomes all have a typical insect mitochondrial gene order, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and one A + T rich region (control region). The PCGs are initiated by the typical ATN codons, except CGA for the cox1 gene. Most PCGs terminate with common codon TAA or TAG, the incomplete codon T is found as the stop codon for cox2, nad4, and nad5. Most tRNA genes exhibit typical cloverleaf structure, except trnS1 (AGN) lacking the dihydrouridine (DHU) arm. The secondary structure of rRNA of four mitogenomes were predicted. Poly-T structure and micro-satellite regions are conserved in control regions. The phylogenetic analyses based on 13 PCGs showed the relationships of subfamilies in Pyraloidea. Pyralidae, and Crambidae are monophyletic, respectively. Pyralidae comprises four subfamilies, which form the following topology with high support values: (Galleriinae + ((Pyralinae + Epipaschiinae)+ Phycitinae)). Crambidae includes seven subfamilies and is divided into two lineages. Pyraustinae and Spilomelinae are sister groups of each other, and form the "PS clade." Other five subfamilies (Crambinae, Acentropinae, Scopariinae, Schoenobiinae, and Glaphyriinae) form the "non-PS clade" in the Bayesian inference tree. However, Schoenobiinae is not grouped with the other four subfamilies and located at the base of Crambidae in two maximum likelihood trees.
