Gandaritis evanescens (Butler)

( Fig. 37 )

Gandaritis evanescens : Beljaev & Mironov 2019: 264 (Sakhalin).

Material examined. 1 ♂, S Kholmsk, 27.VII.2017 ; 16 ♂, 4 ♀, Yasnomorskoe and Sokhonda mount., 19, 20, 21, 23, 26.VII.2019; 1 ♂, 4 ♀, Sokhonda mount., 11–13.VIII.2020.

Distribution. Russia (S RFE: SW Sakhalin, S Kurils—Iturup and Kunashir), Japan (Hokkaido, Honshu, Shikoku, Kyushu, Tsushima, Yakushima), South Korea, China (Central, SE, SW).

Remarks. The finding of G. evanescens in Sakhalin significantly expands its distribution range to the north. The examined moths have narrowed dark elements in the wing pattern, which is characteristic to the moths from Hokkaido described as a subspecies G. evanescens borearia Inoue. In Japan the known host plants of the larvae belong to Hydrangea and Schizophragma ( Hydrangeaceae ); of them Hydrangea paniculata is common in SW Sakhalin and the moths of this species were usually observed closely associated with the thickets of this plant.
