The genus Pholcus Walckenaer, 1805 is the largest genus among the cellar spider family Pholcidae C.L. Koch, 1850, including 339 species. To date, 33 species in the genus are known to be distributed in Korea, being placed into three species-groups(crypticolens-group, phalangioides-group, and phungiformes-group). About 91% of these species are endemic to Korea. In this study, four new species of the genus Pholcus were discovered in Korea, viz, Pholcus chuncheonensis Lee, Choi and Kim sp. nov., Pholcus pajuensis Lee, Choi and Kim sp. nov., Pholcus pocheonensis Lee, Choi and Kim sp. nov., and Pholcus unaksanensis Lee, Choi and Kim sp. nov. These new species are classified as members of the phungiformes-group, having morphological characteristics such as male chelicerae with a frontal apophysis, palpal tibia with a prolateroventral tubercle, and genital bulb without appendix or having pseudo-appendix, but can be distinguished from congeners by characteristics of the male palp and female genitalia. Detailed descriptions and a key to new species are provided with accompanying photographs.

A poorly known spider, Pholcus kwangkyosanensis Kim & Park, 2009 is redescribed with diagnosis, detailed descriptions, and taxonomic photographs of diagnostic characters. P. kwangkyosanensis is similar in appearance to P. kwanaksanensis Namkung & Kim, 1990, in terms of the shape of the genital organ and body, but it can be easily distinguished from the latter by the shape of the cheliceral apophysis, uncus, and procursus in males, as well as the shape of the epigynum and pore plates in females. The specimens of this spider were collected at the type locality (Mt. Gwanggyosan, Suwon), specifically under the bridge on a local stream in an agricultural landscape surrounded by rice fields, upland fields, or horticultural greenhouses.
