Two Geometrid Species, Mixochlora argentifusa and Scopula tsushimana (Lepidoptera: Geometridae), New to Korea

Two geometrid species, Mixochlora argentifusa (Walker, 1861) and Scopula tsushimana Kaneko, 2018, were newly recorded from Korea. Mixochlora argentifusa, a species of Geometrinae, is characterized by dark greenish, inverse triangular central fascia with a large lunular discal dot and a thick subterminal line of the falcate forewing and band-shaped medial and subterminal lines of the hindwing. Scopula tsushimana, a species of Sterrhinae, is characterized by dark blackish, slanted, dentate ante- and postmedial, and subterminal lines with a black, minute discal dot of the forewing and a relatively thick, blackish antemedial line and strongly undulating postmedial and subterminal lines of the hindwing. We provide diagnosis, description of adults and immatures, if available, and illustrations of the adults, and male and female genitalia.
