The genus Clubiona Latreille, 1804 is the most diverse and largest one in the family Clubionidae Wagner, 1887. Twenty-nine species of the genus have been described in various ecosystems from Korea to date. Clubiona semicircularis Tang, Song and Zhu, 2005 which was formerly only known in China and Clubiona ansa n. sp. were collected with a sweep net on the foliage of the shrubs in mixed forests from mountains and agricultural landscape during a seasonal survey of the spider fauna in Korea. This study describes these two species with a diagnosis, measurements, and morphological illustrations. In addition, the female of C. semicircularis is described with a diagnosis for the first time from the present study.

The spider fauna of mountains, including national parks, in Korea was intensively surveyed in 2018-2019. During the seasonal surveys, males of Clubiona bakurovi Mikhailov, 1990 (family Clubionidae Wagner, 1887) and Otacilia ansula sp. nov. (family Phrurolithidae Banks, 1892) were collected from shrub foliage and leaf litter, respectively, in mountainous mixed forests. The males of Otacilia ansula sp. nov. can be easily distinguished from those of other its congeners by the slender and hook-shaped retrolateral tibial apophysis, ovoid distal tegular apophysis, and one dorsal spine on the femur with seven pairs of ventral spines on the tibia of leg I. This study provides descriptions of these two species with diagnosis, measurements, and morphological photographs.

Four species of the families Gnaphosidae and Clubionidae are reported. Cladothela unmunensis n. sp. is described from Gyeongsangbuk-do, Korea. Drassodes longispinus Marusik and Logunov, 1995, Gnaphosa inconspecta Simon, 1878 and Clubiona tongdaoensis Zhang, Yin, Bao and Kim, 1997 are newly recorded to the Korean spider fauna.

Two distinct spider communities were studied in the crowns and ground surfaces of pine plantations at Mt. Ungilsan, Kyonggi-do using pitfall traps and knock-down by spraying of an insecticide (D.D.V.P.) to sample spiders. There were 34 species of 11 families in the ground community and 41 species of 15 families in the crown community, with only 9 species being collected in both. Wandering spiders comprised 78.5% of the crown community and 90.8% of the ground community. Guild abundance and the most abundant families were distinctly different in the two habitats: agile hunters (Salticidae:32.4%) and nocturnal hunters (Clubionidae:19%) in the crown, runners (Lycocidae:32.8%) and nocturnal hunters (Gnaphosidae:31.2%) in the ground. Dominant species were Clubiona jucunda (Karsch) and Mymarachne japonica (Karsch) in the crown, while in the ground they were Pardosa laura Karsch and Gnaphosa silvicola. Species diversity(H ) had peaks in May, July and November in the ground community, while in the crown community peaks were in June and September. The seasonal trends of species diversity (H ) were due mainly to differences in the number of species and the numbers of individuals collected at each sample date rather than to differences in equitability among species. Spier guilds and dominant species have different seasonal patterns based on the temporal differences in prey availability in the two communities and the reduction of temporal overlap.

Hitherto 44 species belonging to 19 families of spiders have been reported at Ulreung-do on the East Sea. Korea. The authors have investigated spider fauna, through out the Ulreung-do, during July 25, August 3. 1975 and July 30, August 7, 1980. The foundings were as followings. 1) In this report, 132 species of 74 genera, including 3 undetermined species, belonging to 25 families of spiders are tabulated by the aid of published data and collections of the authors. Eighty six species are added to the fauna, of which 2 species are new to Korea. as follows; Porrhomma montanum Jackson. 1918, Clubiona neglecta O.P. Cambridge, 1862. The spider fauna of Ulreung-do includes 18 nothern species $(14.0\%)$, 8 southern species $(6.2\%)$. 7 cosmopolitan species $(5.4\%)$ and 84 Palaearctic temperate species $(65.1\%)$. The predominant species are Araneids. Thridiids, especially Cyclosa japonica Boes. et Str. are found in large numbers all over this island. Linyphiids and Lycosids are relatively few in number. 3) The common species to comparative area and foreign countries are as follows; Ulreung-do/Jookbyeon...76 species$(43.3\%)$ Ulreung-do/Jeju-do...95 species$(40.6\%)$ Ulreung-do/Heuksan do...61 species$(35.7\%)$ Ulreung-do/Deogjeog-do...51 species$(31.7\%)$ Ulreung-do/Tsushima Isl....71 species$(30.3\%)$ Ulreung-do/Japan...112 species$(11.3\%)$ Ulreung-do/main China...59 species $(6.5\%)$ 4) The ecological distribution are as follows; The seashore region...81 species$(62.8\%)$ The evergreens region...73 species$(56.6\%)$ The highiands region...64 species$(49.6\%)$ The valleys region...49 species$(38.0\%)$ The basin region...23 species$(17.8\%)$ 5) The noticeable one of geographical distribution in this island, are as follows; Nesticus quelpartensis Paik et Namkung, 1969, Conoculus simboggulensis Paik, 1971.

The diversity of spider communities was investigated in the pine forest of Pinus densiflora in Songri-san, where chemical pesticides had been applied to control pine gall midge (Thecodiplosis japonensis). Spider communities were surveyed in four areas: a pesticide-untreated natural forest (area A), a forest with vinyl-covered ground surface (area B), an aldicarb-treated forest (area C) and a forest treated with a systemic pesticide (phosphamidon) (area D). A total of 74 spider species from 17 families were collected from the four survey areas. There were 54 species from 15 families in area A, 27 species from 12 families in area B, 29 species from 9 families in area C and 34 species from 9 families in area D, respectively. The species diversity of spider communities was highest in pesticide-untreated area A, and much lower in the other three areas. The monthly species diversity of spider communities was highest in May and lowest in January. The similarity of the spider communities was highest in areas B and D. The monthly similarity of the spider communities was highest in November and February. The dominant species was Clubiona jucunda (12.71%, N=304 individuals). According to our results, the application of aldicarb and phosphamidon dramatically decreased spider diversity and the number of individuals in the forests. Thus, the application of these two pesticides to natural forests should be restricted, or alternative pesticides need to be developed. Our results also indicated that application of the pesticides should be avoided in May and June when high spider diversity is expected.
