Scymnus folchinii Canepari, 1979 is reported here for the first time in Korea, based on specimens collected from Dokdo and Ulleungdo Islands, the easternmost islands in the East Sea. Specimens were collected in 2022 and 2024 using malaise traps and sweep-netting in the coastal cliff grasslands of both islands and in grassland adjacent to the Namyang Stream on Ulleungdo Island. In this study, we provide detailed information on the general habitus, diagnostic morphological traits, and COI gene barcodes of the species. Based on COI gene sequences, S. folchinii showed distinct p-distances from S. babai Sasaji (>15.20%) and from S. ferrugatus (Moll) (>14.74%), both species previously recorded on Dokdo Island. This new record from these isolated volcanic islands underscores the need for further research on the genus Scymnus to enhance our understanding of its taxonomy and distribution in Korea.
