Three wolf spiders of the family Lycosidae Sundevall, 1833 are newly described from Korea: Arctosa labiata Tso & Chen, 2004, Pardosa altitudis Tikader & Malhotra, 1980, and Pardosa laevitarsis Tanaka & Suwa, 1986. These spiders were collected during a seasonal survey of the spider fauna of National Parks located in Gangwon-do and Gyeongsanbuk-do in 2018-2019; two males of A. labiata from Mt. Songnisan National Park, one female of P. altitudis from Mt. Chiaksan National Park, and two males of P. laevitarsis from Mt. Odaesan and Sobaeksan National Parks. The three newly recorded spiders have previously been known to be distributed in Taiwan, India, China, and Japan. These spiders were collected by hand in mixed forest leaf litter in mountainous terrains. The present paper taxonomically describes these three wolf spiders with measurements and morphological illustrations.

Pardosa pseudolaevitarsis n. sp. and Hygrolycosa umidicola Tanaka, 1978 belonging to Lycosidae are described from Korea. To date, fourteen species in the genus Pardosa C. L. Koch, 1847 have been described from Korea. H. umidicola belongs to Hygrolycosa Dahl, 1908 was once described from Korea, but the previous description of this species could not provide adequate scientific evidence for adding H. umidicola to the Korean spider fauna. Pardosa pseudolaevitarsis n. sp. is similar to P. laevitarsis Tanaka & Suwa, 1986 in the shape of its epigyne and palp, but can be distinguished by the followings: epigynal atrium small; spermathecae extending to the end of atrium; shape, location and orientation of fertilization duct in epigyne and internal genitalia; blunt basal spur of median apophysis in palp; number, shape and arrangement cheliceral teeth on both margins. Both species were collected using pitfall traps on a ridge between rice fields and seem to prefer habitats with relatively high humidity.
