Male genitalia . Uncus absent; socii inward curved horn apex; tuba analis membranous; tegumen strong; aedeagus 1/2 of length from tegumen to vinculum, bends lightly, deciduous cornuti; vinculum small; caulis inverted trapezoid; basal opening about half width of valva, elliptical shaped; sacculus hairy; valva long, tapering neck; cucullus rounded rectangle, setae moderately dense; one pollex on edge. Female genitalia . Papillae anales with long and short hairs; lamella antevaginalis towering, folds inward, bifid peaks; colliculum long more than half of ductus bursae length; corpus bursae spherical; signa pair, horn-shaped, bent apex, equal size. Host plants. Malus domestica , Prunus tomentosa , Eriobotrya japonica , Pyracantha angustifolia [ Rosaceae ] ( Nasu 2021 ). Distribution. Korea (GG, GW, N) ( Byun 2011 ; Bae et al . 2012 ), China ( Zhang & Li 2005 ), Japan ( Nasu 2021 ), Russian Far East ( Kuznetzov 2001 ). Remarks. The species was first recorded in Korea in Zoological Society of Korea (1968) , and in North Korea by Byun (2011) . It occurs twice a year, and in Korea it has been primarily observed feeding on apple tree leaves ( Shin et al . 1983 ).
