Currently 41 valid species of the Pholcus phungiformes-group (Araneae: Pholcidae) have been known from Korea. In this study, four new species of this species-group were discovered from Gangwon-do and eastern Chungcheongbuk-do. These new species have common characteristics with Pholcus socheunensis, such as broad and membranous prolateral process and strongly curved pseudoappendix in male palp. The female of Pholcus montanus in the original description is the misidentification of a new species. Brief diagnosis, photographs and a distribution map of the new species and P. socheunensis with discussion on their sympatric distribution are provided.
