Sorolopha Lower, 1901 is one of the largest genera belongs to the tribe Olethreutini in the subfamily Olethreutinae Obraztsov, 1946. This genus is distributed throughout the world, including 64 described species (Brown 2005; Horak 2006). Among them, 60 species are distributed mainly in the Oriental Region. Besides, the genus was also recorded from Australian Region (6 species) and Palaearctic Region (2 species). Characteristics of genus Sorolopha are very close to those of Eudemis (Diakonoff 1973). Sorolopha species in Vietnam have been reviewed by Kuznetzov (1988, 2000 & 2003) and Razowski (2009). In 1998, Kuznetzov recorded one new species, S. ghilarovi Kuznetzov in a study on Lepidoptera fauna from the Northern part of Vietnam, and he (2000) also recorded 9 species from the country based on the collection of Zoological Institute, St. Petersburg. Moreover, a new species S. asymmetrana Kuznetzov was described in 2003. Most recently, Razowski (2009) reported 4 known species such as, S. herbifera (Meyrick, 1909); S. sphaerocopa (Meyrick, 1930); S. satoi Kawabe, 1989; S. chiangmaiensis Kawabe, 1989. He also described two species as new to science, S. brunnorbis Razowski and S. dorsichlora Razowski from the collection of the Berlin museum. In this study, a total of 10 species have hitherto been recorded from the Northern part of Vietnam including one new species, S. cucphuongensis sp. nov.. The new species is very similar to S. phyllochlora Meyrick but it can be separated by different characters of wing pattern and socius of male genitalia. The materials for identification are based on the collection of University of Incheon.
