The family Epermeniidae is a small group, comprising 188 described species with 11 genera in the world. In Korea,the family Epermeniidae has only one described species, Epermenia strictella (Wocke, 1867) to date. In this study, thenewly recorded genus Ochromolopis Hübner, 1824 was reported with Ochromolopis kaszabi minima Budashkin & Satshkov,1991 which is a subspecies of Ochromolopis kaszabi Gaedike, 1973 for the first time from Korea. For the exact identificationamong the species, the DNA barcode was conducted with a brief phylogenetic tree by COI gene. All the available informationincluding distributional ranges and host plants were provided in this study. Also, The images for adult and male andfemale genitalia were provided for the taxonomic study.

The family Epermeniidae (Lepidoptera) is a small family with more than 100 described species in the world (Gaedike, 1996). It is divided into two subfamilies, Epermeniinae and Ochromolopinae (Dugdale et al., 1999). Although this family comprises species with variously shaped wings from broad to narrow lanceolate, it is characterized by stiff bristles on the whole surface of the hind tibia. Another character, one or more scale teeth on the dorsum of the forewing seems to be another apomorphy for the family. However, some species lack these teeth by secondary loss (Kuroko, 2006). The family has been poorly known from Korea to date. The first record of Epermeniidae in Korea was Epemenia strictella (Wocke), by Park (1983), on the basis of specimen collected in the Suwon, Province Gyeonggi. Since this report, no research has been conducted on this family in Korea. This study is based on the recent survey on the Microlepidoptera by Korea National Arboretum(KNA) to clarify the fauna of microlepidoptera of Korea. In this study, we report two species of the family Epermeniidae, Phaulernis chasanica and Ochromolopis sp., for the first time from Korea along with illustraton of adults.
