The genus Peromitra Enderlein is a small group of phorid flies, including two European parasitic species known to parasitize larval bibionid flies. In this study, specimens of the Peromitra species collected from South Korea are examined morphologically on the basis of characteristics on ocellar region, leg chaetotaxy and hypopygium. As a result, four species are described new to science and two species, viz. P. fimbriata and P. multisetalis are newly recorded from South Korea. Photographs of diagnostic characters and a key to males of South Korean species are provided.
