Notes

This is the first record for the Korean fauna. The DNA barcode of Hypena obacerralis was first registered in this study (GenBank accession No. PV 274486) and the p-distance with H. zilla was 9.32 %, while the lowest genetic distance of 7.39 % was observed with H. obesalis (Figs 3 d , 9).

Antennae filiform; vertex and frons narrow, greyish-brown, covered with long erected scales; labial palpi dark brown, covered with erected scales on dorsal and ventral surfaces, second segment two times longer than the third segment.
