Complete mitochondrial genome of the Korean endemic earthworm <i>Amynthas righii</i> (Clitellata: Megascolecidae)

<i>Amynthas righii</i> is an earthworm species endemic to Korea, typically inhabiting mountainous forest environments. The specimens were collected from Mount Deogyu, South Korea. The complete mitogenome of <i>A. righii</i> was sequenced, assembled, and annotated. The mitogenome of <i>A. righii</i> is a circular DNA molecule of 15,142 bp with an A + T content of 65.56%, comprising 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a control region. Phylogenetic analysis revealed that <i>A. righii</i> formed a well-supported clade with <i>A. jiriensis</i> and clustered with related taxa within the <i>Amynthas</i> lineage.
