  • 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.

  • 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.

  • Araneidae Clerck, 1757 is one of the largest families within the order Araneae Clerck, 1757, comprising 3,065 species in 177 genera. To date, two species of the genus Mengora O. Pickard-Cambridge, 1889 and four species of the genus Araniella Chamberlin & Ivie, 1942 have been recorded in Korea. During a seasonal survey of the spider fauna in mountainous terrain conducted from 2018 to 2019, females of Mangora foliosa Zhu & Yin, 1998 and a male of Araniella robusta sp. nov. were collected with a sweep net between shrubs in mixed forests from Mt. Juwangsan National Park. In this paper, we provide a diagnosis of the new species and descriptions including measurements and morphological illustrations. The new species, Araniella robusta sp. nov., can be easily distinguished from other species in the genus Araniella Chamberlin & Ivie, 1942 by a branched conductor with two blunt tips and conjugation of the embolus tip and terminal apophysis.

  • Species of the genus Eopompilus Gussakovskij, 1932 from South Korea are reviewed. Three species are confirmed: E. internalis, E. luteus, and E. minor. Eopompilus luteus is recorded for the first time in Korea, and is easily separated from its congers by markedly extensive coloration and comparatively large body size in both sexes. Females are characterized by yellowish wing, light brown stigma and veins, lacking of subapical or apical dark fascia on forewing. Males are characterized by serrate antenna formed by submesal convex on each flagellomeres 2-11, symmetrical claws of fore tarsus, hypopygium widened basally and forming a rhomboid plate, lacking of dark fasciae in forewing. The specimen identified as Cryptocheilus nicevilli Bingham from Korea by Kim (1970) is examined and is reclassified as conspecific with E. luteus. A key is presented of the three species complemented by digital images and diagnosis.

  • 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.

  • 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.

  • Philodromidae Thorell, 1869 is one of the most diversified and largest families comprising 522 species in 29 genera within the order Araneae Clerck, 1757. The genus Thanatus C. L. Koch, 1837 comprise 99 species of the family and four species of the genus Thanatus (Philodromidae) have been recorded in Korea: T. coreanus Paik, 1979, T. miniaceus Simon, 1880, T. nipponicus Yaginuma, 1969, and T. vulgaris Simon, 1870. Two females of T. arcticus Thorell, 1872 were collected by sweep net between the shrubs in mountainous mixed forests from Mt. Chiaksan National Park, Wonju-si, Gangwon-do and Mt. Naejangsan National Park, Jangseong-gun, Jeollanam-do. The present study describes T. arcticus with measurements and taxonomic illustrations.

  • The paper deals with the finite element modelling of the free vibration and structural behavior of a particular four-floor reinforced concrete structure subjected to static equivalent seismic loads and supported by a shallow foundation system called SNSF (Spider Net System Footing). The two FE models are a simple 2D Matlab model and a detailed 3D model based on solid elastic elements using Altairworks (Hypermesh and Optistruct). Both models can simulate the soil structure interaction. We concentrate on the behavior of a representative cell involving two columns on five levels. The influence of the boundary conditions on the external vertical planes of the domain are duly studied. The Matlab model appears relevant for a primary estimation of frequencies and stiffness of the whole structure under vertical and lateral loads.
