Notes

This is the first record for the Korean fauna. The DNA barcode of Hypena perspicua was first registered in this study (GenBank accession No. PV 274488). The p-distance with H. proboscidalis and H. tamsi was 9.99 %, while the lowest genetic distance (5.07 %) was recorded for H. nigrobasalis (Figs 5 e, 8 c, d).
