Diagnosis. The forewing pattern and male genitalia of this species closely resemble that of Phyllonorycter jozanae ( Kumata, 1967) , but can be distinguished by the following characteristics. In P. issikii , the first costal, first and second dorsal strigulae are strip-shaped, slender, the first costal strigula located beyond the first dorsal one ( Figs 3–4 View FIGURES 1–6 ); while in P. jozanae , the first costal, first and second dorsal strigulae are triangular, the first costal strigula is opposite to the first dorsal strigula ( Kumata 1967: Plate 8, Fig. 3 View FIGURES 1–6 ). In the male genitalia, the costal processes of P. issikii are asymmetric, the costal process of the right valva is about seven times that of the left valva, distal 2/3 of the left valva is almost equal in width towards the apex, the eighth sternite is slightly oval ( Figs 9–10 View FIGURES 7–10 ); while in P. jozanae , the costal processes are symmetrical, the left valva is narrowest at 2/3 and then is gradually widened, and the eighth sternite is elongate trapezoid ( Kumata 1967: Fig. 3 View FIGURES 1–6 ). No reliable diagnostic characters can be observed in the female genitalia.

Remark. Most of the specimens used in the study are the same as that of the aestival form in the original description, but the four collected from Lushan National Forest Park in Zibo (Shandong, China) on June 6, 2021. These are clearly different from both aestival and autumnal forms on the forewing markings ( Figs 5–6 View FIGURES 1–6 ). In the aestival form the forewings have well-defined strigulae, while in the autumnal form the forewings are covered with more black and white scales, making the forewings gray with almost no markings ( Kumata 1963). However, the forewings of the four specimens mentioned above not only have clear white markings but also have additional black scales. A detailed description is given as follows. Forewing with base streak runs to half of the forewing, sometimes covered and interrupted by black scales; base streak and costal margin covered with black-brown scales. Two costal and two dorsal strigulae, all irregular in shape; first costal strigula at half of forewing, second at distal fourth, with black-brown scales between preceding strigulae; first dorsal strigula at half of wing, second at distal third. Distal part of forewing blackish brown except for the white marking.
