Phyllonorycter issikii ( Kumata, 1963)

( Figs 4D , 6E , 12C )

Material examined. Russia: PK, Gornotaezhnoe , MTS, arboretum, 43.69N, 132.16E, 160 m alt., Tilia taquetii , 8.VII.2011, 1 larva, NK310, KX818601 ; same location, T. amurensis , 16.VII.2013, 1 male (reared from leaf mine), NK141, KX818667 , deposited in INRA; same location, T. mandshurica , 21.VIII.2015, 1 male (reared from leaf mine), M. Ponomarenko leg., NK596, NK596 / [NK596-male] , MK 403708 ( Figs 4D , 6E ) , all deposited in INRA.

Leaf mine. The mine is a flat roundish white blotch with a short preceding epidermal tunnel (which however, may be indistinct), most commonly on the lower side of the leaf ( Fig. 12C ). At the later stage the mine is contracted, with few weak folds on the epidermis covering the mine. Frass in loose grains accumulated in the middle part of the mine. Pupation in the mine, in a light cocoon.

Trophic specialization. Monophagous on Tilia (Malvaceae) : in East Asia— T. maximowicziana , T. japonica , T. kiusiana , T. taquetii , T. japonica ( Kumata 1963; Ermolaev 1977; Kumata et al. 1983), in Europe, Western Russia and Siberia (in nature and / or in botanical gardens)— T. cordata , T. platyphyllos , T. tomentosa , T. × euchlora, T. × europaea, T. sibirica , Tilia americana ( Kirichenko et al. 2017c) .

Distribution. Native in Russia: RFE—KK, PK ( Ermolaev 1977; Baryshnikova & Dubatolov 2007); Japan ( Kumata 1963), Korea ( Kumata et al. 1983), China ( Kirichenko et al. 2017c). Invasive in Russia: Siberia ( Kirichenko 2014; Kirichenko et al. 2017c), European part; Europe ( Šefrová 2002; Ermolaev 2014).
