Abstract
The complete mitochondrial genome of Locastra muscosalis (Walker, 1866) was sequenced and characterized in this study, which was the first reported complete mitogenome of the genus Locastra. The mitogenome of L. muscosalis has a total length of 15,177 bp, encompassing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (rRNAs), and an A-T rich region. Phylogenetic analysis revealed that L. muscosalis is closely associated with Orthaga euadrusalis. These data will serve as a valuable foundation for future investigations into the Epipaschiinae and Pyralidae evolutionary history.
