Two Newly Recorded Species of the Notodontidae (Lepidoptera) from Korea

This paper reports two newly recorded species of Notodontid moths, Nephodonta tsushimensis Sugi and Hiradonta ohashii Nakatomi in Korea. Among them, Nephodonta tsushimensis can be distinguished by the broad central fascia with yellowish-white ante- and postmedial lines of the forewing, grayish hindwing with a paler basal part and dark medial and termen, and the stout, bifurcated uncus, the short, thumb-shaped socii, and a long, strongly sclerotized valva, where long sclerotized costa and a round swelling medial process can be found, and an almost straight, long aedeagus with a thin coecum and dense minute spicules on the vesica. Hiradonta ohashii can be distinguished by the dark brownish forewing with strongly dentate costal part of the postmedial line and grayish apex, and light brown hindwing with a dark basal part and transverse medial line and dark grayish termen, as well as by the slender socii and the medial process of valva, and the long slender distal process of the aedeagus. Thus far, 108 species of Notodontidae moths are known in Korea.
