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.

The fauna of spider species inhabited near paddy fields have been investigated in Chinju and Namhae areas. The spiders collected near the paddy fields in Chinju and Namhae areas were 34 species of 31 genera belonging to 10 families: 34 species on paddy levees; 16 species on barley fields; 17 species on fallow fields; and 18 species on paddy fields. The species diversity was the highest on paddy levee. The dominant species collected from each habitat near the paddy fields were Pardosa astrigera on the paddy levees and barley fields, Pirata subpiraticus on the fallow field, and Pachygnatha clercki on the paddy fields. The spiders inhabited near rice fields can be classified into nine groups based on the ecological and taxonomical characteristics: 1. Pirata spp. 2. Pachygnatha clercki 3. Teridiidae, Erigonidae, Linypidae 4. Tetragnatha spp. 5. Dolomedes surfureus 6. Pardosa spp. 7. Salticidae 8. Thomisidae 9. Clubionidae Among the nine spider groups, the spiders belong to the group 1-5 prefered wet ground or paddy to dry ground, in contrast to the group 6-9 which prefered to live on dry land. The difference of the habitat preference indicated that the former five groups do the important roll as pest predators in paddy, while the latter four group mainly suppress the overwintering pest populations on paddy levees.

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.

Insect pests were surveyed in 5 Rice paddy field areas of Organic paddy field and conventional paddy field. At the each rice-growth period, the occurrence rate of 'Small brawn plant hopper was high at the case of duck raising and rice bran farming on middle stage of rice paddy field in Gang-Hwa region. The occurrence rate of Rice water weevil was high at the conventional paddy field on the early stage of rice paddy field in Yeo-Ju region. In the Hong-Seong region, the occurrence rate of 'Rice water weevil' and 'Green rice leafhopper' was high at the 'duck raising compare to the conventional farming on the early stage of rice paddy field. According to each period, the occurrence rate of insect was high at late stage of rice paddy field, and there was no difference between each region. It showed high-occurrence tendency at duck pasture farming rice paddy field. The major natural enemies were spiders and parasites. Theridiidae and Linyphiidae were highly occurred on the conventional farming rice paddy field in Hong-Seong. Web builders containing Theridiidae, Linyphiidae and Tetragnathidae was occurred more than wandering spiders containing Lycosidae, Clubionidae and Pisauridae at various regions, and then occurrence of spiders was different at the various regions but was not different at each farming system.
