Description

Adults. (Fig. 1 a, b) Length of forewing 10-12 mm in both sexes, wingspan 22-27 mm. Antenna filiform in both sexes. Head and thorax grey. Ground colour of forewing grey; black sub-basal line indistinct; costal half of double antemedial line bent, dorsal half zigzagged; medial fascia ochrous, black or indistinct, but noticeable costally; a reddish-ochrous discal dot near postmedial line; postmedial line doubled, unclear, somewhat zigzagged, wavy; subterminal line dotted, angled twice. Ground colour of hindwing pale ivory, darkening towards termen. Abdomen grey.

Male genitalia. (Fig. 2 a, c, e) Uncus sclerotised, truncate, apically rounded, with subscaphium. Tegumen narrow, peniculus trapezoidally expanded. Transtilla weakly sclerotised. Valva trapezoid; costal margin straight with a finger-shaped process; apical lobe hairy; harpe-like process towards apex, apically clothed with long setae; ventro-distal lobe complex and convolute. Saccular shield elongated spatulate, partly fused to aedeagus. Vinculum rather elongated U-shaped. Aedeagus short, stout, with a band of cornuti and a rather large conspicuous cornutus. Eighth tergite costally diagonal wing-shaped plate with two short clavate processes anteriorly, postero-laterally weakly sclerotised; 8th sternite with anteriorly bent H-shaped plate.

Female genitalia. (Fig. 3 a) Apophyses anteriores half-length of apophyses posteriores. Ostium bursae membranous. Ductus bursae membranous, intertwined with a strong sclerite, with cervix bursae. Corpus bursae membranous, weakly wrinkled, strongly curved. Appendix bursae absent.

Diagnosis

This species can be distinguished from other congeners by its a reddish discal dot on the forewing and pale ground colour of hindwing in the adult. In the male genitalia, only Nycteola asiatica have aedeagus with a conspicuous spinous cornutus and a row of cornuti fields. In the female genitalia, its large convolute ductus bursae can identify it from others.

Distribution

Korea, Japan, China, Russian Far East, Nepal, N India, Afghanistan, Turkmenistan, Central Asia, Iran, the Middle East, Turkey, Caucasus, European part of Russia, Europe ( Kononenko et al. 1998, Fibiger et al. 2009, Sasaki and Kishida 2011, Beljaev et al. 2016).

Ecology

Host plant: Salix eriocarpa , S. koreensis , S. koriyanagi ( Salicaceae ) ( Heo 2012, Jinbo et al. 2019).

Notes

While it is noted that Pak (1959) initially reported the species in Korea, he recorded it as a previously reported species. Nonetheless, based on our findings and current available literature, we believe this to be the first official record of the species in Korea. Kim et al. (1982) only reported N. revayana (Scopoli), but this species has not been listed up to now.
