Parornix ermolaevi Kuznetzov, 1979

( Fig. 11D )

Material examined. Russia: PK, Gornotaezhnoe , forest around MTS, 43.68N, 132.15E, 224 m alt., Corylus sieboldiana , 22.VII.2016, 1 larva, NK546 , MK 403727 ; same location, C. sieboldiana , 22.VII.2016, 1 larva, NK544 , MK 403689 , deposited in INRA.

Leaf mine. The mine is a small blotch, first flat and later slightly contracted ( Phyllonorycter -like mine shape), with a short preceding epidermal tunnel, on the lower surface of the leaf between secondary veins close to leaf margin or deeper in the leaf lamina ( Fig. 11D ). The vacated mine soon gets brown ( Fig. 11D ). Frass in loose grains. Soon the larva leaves the mine and continues feeding under a downfolded leaf margin that is fixed by some spinning. Usually two such shelters are created on the mined leaf ( Fig. 11D ), less frequently on a neighboring leaf. Pupation is on the leaf surface.

Trophic specialization. Monophagous on Corylus : C. heterophylla (Betulaceae) (Baryshnikova 2016); C. sieboldiana (new record).

Distribution. Russia: RFE—AO, KK, PK ( Kuznetzov 1979a; Baryshnikova 2016).
