We have sequenced the entire mitochondrial genome of Jankowskia athleta, that is 15 534 bp in length with a 79.53% A + T content (GenBank accession no. KR822683). The mt genome of J. athleta encodes 37 genes that are typically found in metazoan mt genomes, consists of 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. Within the mt genome of J. athleta, there are six gene reading frame overlaps. The gene order is consistent with other yet sequenced mt genome in Geometridae. The mt genome of J. athleta has a 475 bp A + T-rich region with an A + T content of 93.47%. The result of phylogenetic analysis infers that J. athleta is more closely related to species of Geometridae than other moths.
