The complete mitochondrial genome ofLethe albolineatais a circular molecule of 15,248 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (LrRNA and SrRNA), and a non-coding AT-rich region. All PCGs use the standard ATN start codon, except for COI, which begins with CGA. Eight PCGs employ complete stop codon (TAA), whereas the others use a single T or TA acting as an incomplete stop codon. The AT-rich region is 413 bp in length, which contains a conserved motif common to the other lepidopteran species. Two tRNA-like pseudo-genes are found in the mitochondrial genome ofL. albolineata.The phylogenetic analysis shows thatL. albolineataexhibits most close relationship withL. dura. [ABSTRACT FROM AUTHOR]
