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).
