Russia : PK , Gornotaezhnoe , forest around MTS, 43.68N , 132.15E , 224 m alt., A. caudatum subsp. ukurundense , 22.VII.2016 , 1 larva, NK537 , MK 403685 ,; same location, A. pseudosieboldianum , 25.VII.2016 , 1 larva, NK529 , MK 403719 , deposited in INRA ; same location, host and date, 1 male (reared from leaf mine), 109.3 / [1Cn-2016-male] ( Fig. 8E ), deposited in SIF. Leaf mine. The mine is a relatively large elongated flat blotch, with a very short preceding epidermal tunnel that usually starts nearby secondary vein on the upper side of the leaf ( Fig. 14F ). The mine is white ( Fig. 14F ); an exceptionally dark mine was found on A. caudatum subsp. ukurundense ( Fig. 14G ). The frass is not granular, like in Phyllonorycter species, but has a tar-like aspect and covers the bottom of the mine. Pupation in mine. Trophic specialization. Monophagous on Acer : A. barbinerve , A. japonicum , A. palmatum , A. pseudosieboldianum (Sapindaceae) ( De Prins & De Prins 2018 ), A. caudatum subsp. ukurundense ( new record ). Distribution. Russia : RFE—PK ( Baryshnikova 2008 ); Japan ( Kumata 1963 ).
