We report four larentiine moths, Acolutha pulchella (Hampson), Eupithecia tantilloides Inoue, Gymnoscelis taprobanica Prout, and Axinoptera anticostalis Galsworthy for the first time in Korea. Acolutha pulchella can be easily diagnosed by the orange-colored costal half of the forewing with a thick blackish postmedial band and the yellowish-white hindwing with blackish undulating medial lines. Eupithecia tantilloides can be diagnosed by the relatively thick, blackish postmedial line and a large black discal dot on forewing. Gymnoscelis taprobanica can be diagnosed by the slender forewing with a pointed apex with a weakly undulating postmedial line and the dark grayish hindwing with a blackish postmedial line. Axinoptera anticostalis can be diagnosed by the strongly rounded postmedial line and a blackish horizontal line at the dorsal part of the central fascia of the forewing and the strongly curved postmedial line and yellowish white marking at mid termen of the hindwing. We provide the diagnosis, and photographs of adults and the genitalia of these species as well as the mitochondrial COI gene sequence.
