Phyllonorycter junoniella ( Zeller, 1846)

( Figs 7A , 12E )

Material examined. Russia: SO, Sakhalin Island, Yuzhno-Sakhalinsk, Susunaiskiy mountain range , pass Verblud , 47.00N, 142.83E, 983 m alt., 14.VII.2017, 1 male (sampled by sweep netting from Vaccinium vitis-idaea , Fig. 12E ), NK628 , MK 403691 , deposited in INRA; same location, date and sampling method, 3 males, 1 female, Sakh-Sw-2 / [18-male], Sakh-Sw-3 / [20-male], Sakh-Sw-4 / [21-male], Sakh-Sw-5 / [22-female] ( Fig. 7A ), deposited in SIF.

Leaf mine. No mines were sampled in RFE. According to Ellis (2018), in Europe this species makes a blotch mine on the lower side of the leaf, occupying almost the entire leaf. At the later stage, the mine is significantly contracted so that the leaf margins are strongly pulled together. From the upper side, the leaf surface has a mottled pattern due to partially eaten parenchyma layers; later becomes brown. Pupation in the mine.

Trophic specialization. Monophagous on Vaccinium vitis-idaea (Ericaceae) ( Ellis 2018).

Distribution. Russia: RFE—SO (Sakhalin Island) (new record), Siberia ( Dovnar-Zapol’skiy & Tomilova 1978; Baryshnikova 2008), European part ( Kuznetsov & Baryshnikova 1998); Europe ( De Prins & De Prins 2018); Japan ( Kumata & Nakatani 1995).
