Five new spider species of the genus Pholcus Walckenaer, 1805, P. duryunsp. nov., P. hwaamsp. nov., P. mohangsp. nov., P. woraksp. nov., and P. yangpyeongsp. nov., belonging to the P. phungiformes group in the family Pholcidae C. L. Koch, 1850, are newly described from South Korea. These new species were collected from mixed forests in mountainous, hilly, and coastal terrains. This study provides the diagnoses, detailed descriptions, distribution maps, and taxonomic photographs of these new species.

Two new spider species of the genus Pholcus Walckenaer, 1805, Pholcus deokjeok sp. nov. and Pholcus gangneung sp. nov. in the family Pholcidae C. L. Koch, 1850 are newly described from South Korea. The present new species belong to the phungiformes group in the genus. They are found on rock walls in mountainous mixed forests. This work provides diagnoses, detailed descriptions, and taxonomic photographs for these new species. The unusual shaped and strongly sclerotized embolus of P. gangneungsp. nov. in the Pholcus phungiformes group is the first to be reported.

Two new species, Diduga hastata sp. nov. and Diduga mucronata sp. nov. are described from Laos along with four newly recorded species, D. annulata Hampson, 1900, D. amoenusa Bucsek, 2012, D. allodubatolovi Bayarsaikhan, Li & Bae, 2020 and D. luteogibbosa Bayarsaikhan, Li & Bae, 2020. Illustrations of adults and genitalia of examined species from Laos are provided.

The genus Meganola Dyar, 1898 is reviewed for Korea, with 12 species, including the new species, Meganola parki Oh & Cha, sp. n. Illustrations of adults and genitalia of all the Korean species are provided, with a key to species of Meganola based on the external morphology and male genitalia. All known host plants are provided, some of them newly recorded.

The paper contains the description of two new Meganola Dyar, 1898 species (M. canaliculata Cha & Bae, sp. n. and M. phuana Cha & Bae, sp. n.) and a new record of M. tetrodon (de Joannis, 1928) from Laos. Color figures of adults and genitalia of the examined species are provided.
