The complete mitogenome of Cupido argiades (Lepidoptera: Lycaenidae) was determined in this study. The genome is 15,330 bp long, presenting a typical gene organization and order for completely sequenced lepidopoteran mitogenomes. All protein-coding genes (PCGs) are initiated by ATN codons, except for cox1, which uses CGA as its start codon. Some PCGs harbor TAG (nad3) or incomplete termination codon T (cox1, cox2, nad5), while others use standard canonical TAA as their termination codons. Furthermore, the largest noncoding A+T-rich region with the length of 450 bp contains two microsatellite-like repeats of (TA)9 and a conserved motif ATAGA followed by a 19-bp poly-T stretch.
