Two species, Daulia afralis Walker and Herpetogramma cynaralis Walker, belonging to the family Crambidae, Lepdidoptera, are reported for the first time from Korea, based on the materials collected from Jeju Islands located in the southern part of the Korean peninsula. Both male and female genitalia were dissected and examined. Also, the photos of the external morphology, including the wing patterns, and genitalic characteristics of the two species are taken and redescribed briefly, including distributional ranges and available information. Taxonomic information and synonymies for the species were given and discussed.
