Phyllonorycter sp. 6 (Figs 13 G–H) Material examined. Russia: PK, Gornotaezhnoe, forest around MTS, 43.68N, 132.15E, 224 m alt., Acer pseudosieboldianum, 25.VII.2016, 1 larva, NK540, MK 403701, deposited in INRA. Leaf mine. The mine is a white elongated contracted blotch with three to four folds on the epidermis covering mine, between secondary veins or along leaf margin on the lower side of the leaf (Fig. 13 G–H). Pupation in the mine. Trophic specialization. Monophagous on Acer pseudosieboldianum (Sapindaceae). Distribution. Russia: RFE—PK. Remarks. BIN of unknown species—BOLD: ADF4563. DNA barcode of Phyllonorycter sp. 6 does not no match any Acer -feeding Phyllonorycter species in BOLD. In East Asia, only Ph. orientalis (Kumata) is known to develop on A. pseudosieboldianum (De Prins & De Prins 2018). Phyllonorycter sp. 6 is significantly divergent from Ph. orientalis (7.4% genetic distance) (Table 2). Phyllonorycter sp. 6 may potentially be a new species.
