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). Since there are no specimens held at the Incheon National University, the adult specimens are referred to Byun (2011), and the genitalia are documented according to Nasu (2021).
