Cybalomiinae is a small subfamily of the family Crambidae, reporting 18 genera, 122 species in the world. However, this subfamily of species are still included in subfamily Pyraustinae in Korea with two species: Trichophysetis cretacea (Butler, 1879) and T. rufoterminalis (Christoph, 1881). Recently, these species transferred to Cybalomiinae by Shaffer et al. (1996). However, it was not considered in Korea. In the present study, we report the subfamily Cybalomiinae from Korea for the first time, with a newly recorded genus. Illustrations of adults, male and female genitalia, diagnosis, description are provided.
