Distribution. Russia (S RFE: S Amurskaya Obl., JAO, S Khabarovskii Kr., Primorskii Kr., S Sakhalin, S Kurils — Kunashir, Shikotan); China, Korea, Japan (Hokkaido, Honshu, Shikoku, Kyushu, Tsushima, Tanegashima, Yakushima, Amami Oshima).

Remarks. A new species for Kunashir; reference of G. fixseni for this island in Vasilenko, Dubatolov (2021) is erroneous. In Japan moths can be seen from June to November, probably in two or three generations ( Nakajima, Yazaki 2011). In S RFE, at northern limit of its distribution, the species develops in one generation and flies in August and September. Larvae feed on various species of Actinidia ( Beljaev 2016) , in Japan also on Schizophragma hydrangeoides ( Hydrangeaceae ) ( Nakajima, Yazaki 2011).
