Twelve species of the genus Aulacorthum Mordvilko 1914 (Sternorrhyncha: Aphididae) are recognized from the Korean Peninsula. One new species, Aulacorthum ixeridis n. sp., is described for apterous and alate viviparous females on Ixeris chinensis var. graminifolia (Ledeb.) H. C. Fu and Lactuca indica L. (Asteraceae). From the allied species, Aulacorthum nepetifolii Miyazaki 1968, Aulacorthum ixeridis n. sp. is distinguished by the relatively short ultimate rostral segment (0.83–1.07 × as long as the second segment hind tarsus), the dense spinules on head and the triangular short cauda. Host plants of the Korean Aulacorthum are reviewed and the identification key to subgenera and species is also presented.
