A new species of Adoxophyes is described, illustrated, and distinguished from closely resembling species. Larvae of this species were discovered on sweet cherry (Prunus avium) imported from China and intercepted under plant quarantine inspection at Korean sea- and airport. They were reared to adult in the laboratory for identification. We provide a full description of the new species based on adult of female external structures. In addition, we conducted a comparative study of three related species (A. orana, A. honmai, and A. new species) and provided a key to distinguish them.
To confirm the identity of new species, we compared barcoding sequences (~472 bp) of the mitochondrial cytochrome c oxidase subunit I (COI) gene from 11 specimens of three Adoxophyes species. As a result of this study, we confirmed the identity of Adoxophyes new species. We also provided pairwise p-distances among the species and their neighbor-joining tree.
