description
(Figs 14 B – C) Material examined. Russia: PK, Gornotaezhnoe, forest around MTS, 43.68 N, 132.15 E, 224 m alt., Juglans mandshurica, 23. VII. 2016, 1 larva, NK 533, MK 403680, deposited in INRA. Leaf mine. The mine is a small oval silvery white blotch, slightly contracted in the late stage, usually without preceding epidermal tunnel; situated at the leaf margin on the upper side of the leaf (Fig. 14 B). Pupation in the mine, at the corner of the mine, in a slight depression similar to that observed in Phyllocnistis (Fig. 14 C). Trophic specialization. Monophagous on Juglans mandshurica (Juglandaceae). Distribution. Russia: RFE — PK. Remarks. BIN of unknown species — BOLD: ADF 4351. DNA barcode of Phyllonorycter sp. 8 is 3.1 % divergent from the DNA barcodes of four Ph. pterocaryae (Kumata) specimens collected in Japan on J. mandschurica, whose identity was confirmed by adult morphology (Ohshima: personal observation). The fact that Phyllonorycter sp. 8 larvae feed on the same host as Ph. pterocaryae and make similar mines suggests that our finding may correspond to Ph. pterocaryae, which might have high intraspecific genetic variability. According to early records, Ph. pterocaryae is known in the southern part of Primorskii Krai (Baryshnikova 2008, 2016). In BOLD, there are three other BINs corresponding to Phyllonorycter feeding on Juglandaceae: the two unidentified species on Platycarya (Taiwan), Pterocarya (Vietnam), and one Phyllonorycter juglandis (Japan). Phyllonorycter sp. 8 matches none of these species, showing the divergence from them: 4.4, 7.5 and 11.8 %, respectively (Table 2).
