A bibliographic checklist of Korean spiders from the 1956 checklist by Paik and Kim is presented, with a complete bibliography of the relevant Korean araneological literature. For the period of 1907-2009, a total of 507 publications on the spiders were extensively searched and records of taxonomic descriptions were included. Records are listed only from the locations within the present borders of South Korea. A total of 681 species of 258 genera belonging to 46 families were confirmed to exist in Korea. Twenty species, namely Pholcus pojeonensis, Pholcus kwangkyosanensis, Pholcus parkyeonensis, Dysdera crocata, Miagrammopes coreensis, Parasteatoda culicivora, Spheropistha melanosoma, Bathyphantes major, Araneus viperifer, Larinia onoi, Neoscona holmi, Pardosa isago, Pardosa monticola, Trochosa spinipalpis, Anahita samplexa, Cheiracanthium lascivum, Cheiracanthium eutittha, Clubiona japonica, Rhene myunghwani, and Sitticus sinensis, whose distribution or existence within the Korean border were uncertain and did not meet the requirements for valid records were excluded from the present list following critical validation. Sixteen species, namely, Clubiona bakurovi, Clubiona corrugata, Clubiona hummeli, Clubiona komissarovi, Clubiona kulczynskii, Clubiona microsapporensis, Clubiona orientalis, Clubiona paralena, Clubiona propinqua, Clubiona proszynskii, Clubiona sapporensis, Mendoza nobilis, Pseudicius koreanus, Sibianor nigriculus, Sitticus penicilloides, and Yllenus coreanus, which have been described or reported to exist in North Korea were listed separately from the present list. From the zoogeographical distribution, Korean spider fauna was found to be influenced by northern species, including 35 Holarctic and 67 Palearctic species, which account for 14.9% of the total number of species. Korean endemic species include 131 species, which account for 19.2% of the total number. Among neighboring countries, Korean spiders are most similar to those found in Japan. This list (ver. 2010) will be revised periodically after this version.
