( Figs 4H , 7B , 12H )

Leaf mine. The mine is an oval white blotch with 1–2 light folds on the epidermis covering the mine, with distinct epidermal tunnel; situated on the lower side of the leaf along, on narrow leaves of Salix along the main vein ( Fig. 12H ). Loose grains of frass are accumulated in the corner of the mine ( Fig. 12H ). Pupation in the mine, in the central part ( Fig. 12H ).

Trophic specialization. Oligophagous on Salicaceae : Populus , Salix , Chosenia ( De Prins & De Prins 2018) .

Distribution. Russia: RFE—AO, KK, PK, SO (Sakhalin Island) ( Baryshnikova & Dubatolov 2007; Baryshnikova 2016), Siberia ( Baryshnikova 2008), European part ( Baryshnikova 2008); Japan ( Kumata 1963), Korea ( Park 1983), Central Asia ( Noreika 1991), Europe ( De Prins & De Prins 2018).
