Notes

This is the first record for the Korean fauna. The DNA barcode of Hypena tamsi was first registered in this study (GenBank accession No. PV 274484) and the p-distance with H. pulverulenta was 10.25 %, while the lowest genetic distance of 0.15 % was observed with H. proboscidalis (Figs 2 b , 7 e , f ).

Diagnosis

Wingspan 35 mm. Antennae filiform with cilia; vertex anFd frons covered with long greyish-brown scales, distal tip ochreous; labial palpi long, covered with greyish-brown scales, second segment straight, more than three times longer than the third segment, third segment with ochreous distal end. Thorax greyish-brown; tegula consisting of long scales and hair-like scales. Forewing greyish-brown with numerous short dark brownish lines; antemedial line dark brown, undulating; postmedial line distinct, dark brownish, slightly curved at costal 2 / 3; subterminal line weakly undulating. Hindwing paler than forewing, greyish-brown. Abdomen greyish-brown. Male genitalia. Uncus long, weakly hooked, apex sharply pointed. Tegumen hood-shaped; tuba analis long; juxta broad, thick hexagon-shape on its side; saccus shallow, semi-rounded. Valva simple, stout, weakly sclerotised; costal margin almost flat, outer 1 / 4 weakly swollen; sacculus ventral margin medially weakly invaginated; basally a slender division of clavus with a minute process. Aedeagus rod-shaped, anteriorly with dense spicules; vesica large sac-shaped, cornuti a mass of large spines.
