Phyllonorycter orientalis ( Kumata, 1963)

( Fig. 12G )

Material examined. Russia: PK, Gornotaezhnoe , forest around MTS, 43.68N, 132.15E, 224 m alt., Acer pictum , 22.VII.2016, 1 male (reared from leaf mine), NK536 , MK 403726 ; same location, A. pictum , 23.VII.2016, 1 larva, NK535 , MK 403729 ; same location, A. saccharum , 26.VII.2016, 1 larva, NK538 , MK 403707 , all deposited in INRA.

Leaf mine. The mine is an elongated contracted whitish blotch, without preceding epidermal tunnel, with one pronounced fold on the epidermis; situated on the lower side of the leaf nearby the leaf margin ( Fig. 12G ). Loose grains of frass are accumulated in the central part of the mine. From the upper side, the mine is white ( Fig. 12G ). Pupation in the mine.

Trophic specialization. Monophagous on Acer : A. carpinifolium , A. palmatum , A. pictum , A. pseudosieboldianum (Sapindaceae) ( De Prins & De Prins 2018), A. saccharum (new record).

Distribution. Russia: RFE—PK, SO (Kuril Islands) ( Ermolaev 1977; Baryshnikova 2016), European part ( Baryshnikova 2008); Japan, Taiwan ( Kumata 1963), Korea ( Park & Han 1986).
