  • Kim (1970) was an early, comprehensive foundation for the taxonomy of Korean spider wasps. All the species therein are reviewed, and an annotated checklist comprising 21 species is presented. Species names are corrected in terms of current taxonomy. Based on the re-examination of voucher specimens, five misidentifications are rectified, of which two species rectified as Priocnemis(Leptopriocnemis) cyphonota and P.(Umbripennis) pseudojaponica are new to Korea. Also, occurrences of two species (Anoplius eous and An. viaticus) in Korea, which was doubted by Lelej et al. (1994), are confirmed. On the other hand, exclusions of two species (Irenangelus perinx and Priocnemis mitakensis) from the Korean fauna are proposed. However, the need for further study on six species (Anoplius reflexus, An. infuscatus, Arachnospila eisukei or Ar. fumipennis eisukei, Auplopus obtusus, Priocnemis irritablis) historically mentioned for the Korean fauna is newly recognized. The current taxonomic status of those species is briefly discussed.

  • The genus Pholcus Walckenaer, 1805 is the largest genus among the cellar spider family Pholcidae C.L. Koch, 1850, including 339 species. To date, 33 species in the genus are known to be distributed in Korea, being placed into three species-groups(crypticolens-group, phalangioides-group, and phungiformes-group). About 91% of these species are endemic to Korea. In this study, four new species of the genus Pholcus were discovered in Korea, viz, Pholcus chuncheonensis Lee, Choi and Kim sp. nov., Pholcus pajuensis Lee, Choi and Kim sp. nov., Pholcus pocheonensis Lee, Choi and Kim sp. nov., and Pholcus unaksanensis Lee, Choi and Kim sp. nov. These new species are classified as members of the phungiformes-group, having morphological characteristics such as male chelicerae with a frontal apophysis, palpal tibia with a prolateroventral tubercle, and genital bulb without appendix or having pseudo-appendix, but can be distinguished from congeners by characteristics of the male palp and female genitalia. Detailed descriptions and a key to new species are provided with accompanying photographs.

  • The spider fauna of rice fields, marshes, and reclaimed lands was intensively explored in 2015-2022. During the seasonal survey, six Tibellus spiders were collected; two of them, Tibellus fengi Efimik, 1999 and Tibellus japonicus Efimik, 1999, were new to Korean spider fauna and four of them were identified as new species, Tibellus deokjeok sp. nov., Tibellus gimcheon sp. nov., Tibellus sihwa sp. nov., and Tibellus yeongdong sp. nov.. Four new species are similar to each other and known species in the shape of the genital organ and body appearance in both sexes, but can be distinguished from the other Tibellus members by the shape of embolus, conductor, retrolateral tibial apophysis, and ventral tibial apophysis in male and median septum, receptaculum, spermatheca, and copulatory duct in female. The present study taxonomically describes these six Tibellus spiders with diagnoses, measurements, and morphological photos with a key to the Korean Tibellus species.

  • A new species of the genus Ebrechtella Dahl, Ebrechtella juwangensis n. sp. and the male of Ozyptila geumoensis Seo and Sohn, 1997 are reported new to science. Ozyptila utotchkini Marusik, 1990 is reported for the first time in Korea. Habitus photos and illustrations of these three species are provided.

  • 검은과부거미의 독 분비장치는 두흉부에 있는 가위턱과 한쌍의 독선으로 이루어져 있다. 독선은 한겹의 얇은 장막과 횡문근 섬유의 다발에 의해 둘러싸여 있었고. 근육층을 따라서 운동신경의 축삭 돌기와 근섬유 사이에 신경근육간 연접이 형성되어 있었다. 분비상피를 이루는 단층 원주상피세포에는 복잡한 수지상의 돌기가 형성되었고, 독선 전체가 단포상선을 이루고 있음이 관찰되었다. 상피의 분비면은 기저막으로부터 선의 내강쪽으로 확장된 세포질 돌기에 의해 표면적이 현저히 증가되었고, 상피의 내강면에는 조밀한 미세융모가 형성되어 있었다. 독성 분비물은 상피세포 내에서 두 종류의 분비과립으로부터 생성되었다. 분비기동안 이들 분비과립은 과적의 형태로 변형, 농축된 후, 이출분비의 형태로 내강으로 방출되었다. 방출 후의 기저부 상피세포들은 고도의 증식과정을 거쳐 원주상의 상피세포로 재생됨이 확인되었다.

  • Arcuphantes catillus n. sp., a new species of the genus Arcuphantes Chamberlin and Ivie, 1943 is described from Korea. The present species is distinguishable from its known similar congeners by a conspicuous proximal process and a blunt lateral process of the paracymbium, feathery tipped lamellar extension of the pseudolamella, and bowl-like posterior part of radix. The present new species was collected from the leaf litter layer of mixed forest on a hillock around rice fields with a pitfall trap.

  • Two linyphiid spiders, Saitonia kawaguchikonis Saito & Ono, 2001 and Asthenargus niphonius Saito & Ono, 2001 were confirmed from Korea for the first time. Males of S. kawaguchikonis and a female of A. niphonius were collected with pitfall traps in a leaf litter of mixed forests in three National Parks (Hallyeohaesang National Park, Mt. Naejangsan, and Mt. Sobaeksan) during the seasonal surveys for the spider fauna in mountainous terrain from 2018 to 2020. These two species were formerly known from China and Japan, or only from Japan, respectively. The present study describes these two species with measurements, morphological illustrations, and a distribution map. This report adds the genus Asthenargus Simon & Fage, 1922 from Korea to the Korean spider fauna for the first time.
