Abstract
The complete mitochondrial genome (mitogenome) of Melanitis leda (Lepidoptera: Nymphalidae: Satyrinae) is a circular molecule of 15,122 bp in length, containing 37 typical animal mitochondrial genes and 1 control region, known in insects as the AT-rich region. Its gene content and order are identical to all other available butterfly mitogenomes. All protein-coding genes (PCGs) start with a typical ATN initiation codon, except for COI, which is initiated by the CGA codon as observed in other butterfly species. A total of 97 bp of intergenic spacers are interspersed in 11 regions, ranging in size from 1 to 45 bp. The 314-bp-long AT-rich region is the smallest of all the butterfly corresponding regions available and contains some conserved structures similar to those found in other butterfly mitogenomes, including the motif ATAGA followed by a 19-bp poly-T stretch and a microsatellite-like (AT)6 element preceded by the ATTTA motif.
