  • 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.

  • Five erigonine spider species are described with illustrations: a new species, Saitonia pilosus n. sp., and four records new to the Korean spider fauna, Ceratinella brevis (Wider, 1834), Erigone atra Blackwall, 1833, Maso sundevalli (Westring, 1851), and Parasisis amurensis Eskov, 1984. The occurrences of four spider genera, Ceratinella Emerton, 1882, Maso Simon, 1884, Parasisis Eskov, 1984, and Saitonia Eskov, 1992, are also new to Korea.

  • The fauna of spiders in streamsides were surveyed by pitfall trapping at three sites (Gichun-ri, Duckwoo-ri and Haechang-ri) in Paltan-myun in Hwasung areas, Gyeonggi-do. Total 83 spider species and 63 genera belonging to 20 families were identified from 3,128 spiders collected. Species richness and abundance are high in Linyphiidae and Lycosidae and these two groups comprised 60.7% of total collected spiders. Thirty-six species (43.4%) were Iveb builders and 47 species (56.6%) were hunters. This study was the first survey on streamside spiders form Korea and will be valuable in the management of biological resources and description of biodiversity, and augment for utilizing them as a biological control agent in agricultural landscape.

  • Description and identifications of 6 species belonging to genus Phintella from Korea are in insufficient and inaccurate situation. In the present paper, redescriptions illustrations and identification key are provided for 7 species of genus Phintella including P. popovi newly recorded in Korean spider fauna, and Ocius munitus described by Wesolowska (1981s) was synonymized to P.cavaleriei. For the author's identiication and pairing to be valid multivariate analysis was performed with 13 RVCs below STD 0.05 to 134 individuals. The result of discriminant analysis carried out with 13 RVCs of 134 individuals was not satisfactory, but cluster analysis performed with mean ratio values of 14 OTUs to 13 RVCs showed the same result with author's pairing except P.abnormis , which has larger dissimilarity than the pairs of the others. So pairing of 7 species was possible as a whole because one species only failed in pairing , even though this is imperful result. This method to be helpful to pairing test and identification if it were to improve.
