Comibaena amoenaria (Oberthür)

( Fig. 21 )

Comibaena tancrei , nec (Graeser): Viidalepp 1979: 844 (Sakhalin); Viidalepp 1996: 64 (Sakhalin?).

Comibaena amoenaria : Beljaev & Mironov 2019: 254 (Sakhalin).

Material examined. 1 ♂,Yuzhno-Sakhalinsk, STAZR, 12.VIII.2008; 1♂, 3♀, S Kholmsk, 21.VII.2017, 28.VII.2018, 21.VII. 2021, 22.VII.2022 ; 5 ♂, 4 ♀, Yasnomorskoe and Sokhonda mount., 18, 19, 20, 22, 24, 26.VII.2019.

Distribution. Russia (S RFE: S Sakhalin, S Kurils—Kunashir, S Khabarovskii Krai, S Amurskaya Oblast, Primorskii Krai; S Siberia east to Baikal region), Japan (Hokkaido, Honshu, Shikoku, Kyushu, Tsushima), North Korea, South Korea, N China (Beijing Shi: BOLD Sequence ID: GWOTL766-13, as “ Comibaena cassidara ”: Makhov & Lukhtanov 2021).

Remarks. The finding of C. amoenaria in Sakhalin significantly expands its distribution range to the northeast. Probably, the reference of the continental species C. tancrei for Sakhalin ( Viidalepp 1979) is based on the erroneous identification of C. amoenaria as a result of the external resemblance of the moths.

In Japan the larvae feed on various species of Fagaceae ( Quercus serrata , Q. crispula , Fagus crenata , Lithocarpus edulis ), and on Salix babylonica ( Salicaceae ). Possibly, they are polyphagous on various leaved trees, considering the species distribution in S Siberia, where Fagaceae are absent. In Sakhalin the moths fly from mid-July to mid-August, the species develops in one generation.
