Abstract

A depressariid moth, Agonopterix issikii Clarke, 1962, feeing on Orixa japonica was newly recorded from Korea. Agonopterix issikii can be characterized by the brownish forewing mottled dark brown and black scales that show a dentate line at the base and three minute blackish dots in triangular at the median, and the basally pale gray hindwing. Agonopterix issikii is similar to A. ocellana Fabricius in external appearance but can be distinguished by the presence of brownish forewing with three blackish triangular dots at the median. The male genitalia of Agonopterix issikii can be characterized by the elliptic gnathos, the triangular socius, the rectangular valva with rather straight cuiller, and the stout phallus with a short basal process and the absence of cornutus. The female genitalia can be characterized by the funnel-shaped ostium bursae, the long ducuts bursae, and the ovate corpus bursae with a rounded patch of signa. To date, 12 species of the genus Agonopterix have been recorded in Korea.
