* Inurois fumosa Inoue, 1944 ( Figs 3 F , 4 F )

Material. Andreevskii Cordon , at light, 21.11.2023 – 1♂ ; ibid., 22– 23.11.2023 – 3♂ ; ibid., road on a slope, alder forest, at evening by net, 21.11.2023 – 2♂ ; ibid., plateau, birch forest, at night, 21.11.2023 (Zinchenko) – 6♂ ; ibid., at night, 22.11.2023 – 25♂ (Dubatolov, Zinchenko) . Photos of moths: 6 km NW of Yuzhno-Kurilsk, Lagunnoe Lake, 44 ° 03′46″ N, 145 ° 45′36″ E, 2.12.2023 (Stefanov) .

Distribution. Russia (S RFE: S Amur Obl., Jewish A.O., S Khabarovsk Kr., Primorsky Kr., S Kurils – Kunashir); South Korea, Japan (Hokkaido, Honshu, Shikoku, Kyushu), China (Shaanxi,? Sichuan, Taiwan Island) (for the details see Beljaev 2022).

Remarks. The species is new for the Kuril Islands. On Kunashir, the moths were observed in the last third of November and early December, appearing later than other winter geometrids, with the exception of Inurois punctigera . In Japan, in the plains and low mountain areas of the Kanto region (Honshu Island) I. fumosa appears from late December to late January, with a peak flight in mid-January, whereas in mountains it flies from mid-November to early December (Nakajima 2011). In the continental part of the RFE, the moths are observed from early October (in the north of its range and in mountains) to mid-November (in south) ( Beljaev 1996). The larvae feed on various leaved woody plants.
