Five spider species from the genus Pholcus Walckenaer, 1805, namely Pholcus geogeum sp. nov., Pholcus hongseong sp. nov., Pholcus gochang sp. nov., Pholcus jeocheon sp. nov., and Pholcus yongin sp. nov., are newly described from Korea. These five new species, which belong to the phungiformes group within the genus, can be distinguished from their congeners by the shape and structure of the genital organs of both males and females. They are found on rock walls and at cave entrances in mountainous and hilly mixed forests. This study provides diagnoses, detailed descriptions, and taxonomic photographs of the newly described species.
