After the revision of the Korean species of Asthena $H{\ddot{u}}bner$, we additionally added one new species, Asthena koreana sp. nov. and two new records, Asthena hamadryas Inoue and Asthena sachalinensis (Matsumura) from Korea. Asthena koreana sp. nov. can be characterized by the white forewing with a costally bifurcated, loop-shaped antemedial line, black minute discoidal dot and single postmedial line and white hindwing with straight antemedial line and black discoidal dot. Asthena hamadryas Inoue can be distinguished by a white forewing with a costally loop-shaped antemedial line and undulating, double lines of the postmedial line, as well as a white hindwing with four light ochreous waved lines without discoidal dots. Asthena sachalinensis can be distinguished by their whitish forewing with thick light brownish postmedial lines and minute black discoidal dot on the costal loop of the antemedial line and whitish hindwing with light brownish medial lines with minute black discoidal dot. Currently, eight species of the genus are known in Korea. We provided a revised key to the Korean species of the genus.
