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.
