Notes

This is the first record for the Korean fauna. The DNA barcode of Hypena pulverulenta was first recorded in this study (GenBank accession No. PV 274491). The p-distance with H. proboscidalis and H. tamsi was 10.25 %, while the lowest genetic distance (6.63 %) was recorded for H. obesalis (Figs 4 b, 8 a, b).
