Idiotephria evanescens (Staudinger)

( Fig. 33 )

Material examined. 2 ♂, S Kholmsk, 21.VI.2021, 21.V.2022 .

Distribution. Russia (S RFE: SW * Sakhalin, S Kurils—Kunashir ( Rybalkin et al. 2022), S Khabarovskii Krai, Primorskii Krai), Japan (Hokkaido, Honshu, Shikoku, Tsushima), South Korea.

Remarks. The finding of I. evanescens in Sakhalin significantly expands its distribution range to the northeast. Both examined specimens, as well as the moth from Kunashir ( Rybalkin et al. 2022, fig. 34) possess unusually light coloration of wings, which is also occurs in the moths from Hokkaido. The known hostplant in Japan is Quercus mongolica subsp. crispula ( Fagaceae ), which is widely, but sparsely occurs in S Sakhalin as well.
