Bibliographic Check list of Korean Spiders (Arachnida: Araneae) ver. 2010

A bibliographic checklist of Korean spiders from the 1956 checklist by Paik and Kim is presented, with a complete bibliography of the relevant Korean araneological literature. For the period of 1907-2009, a total of 507 publications on the spiders were extensively searched and records of taxonomic descriptions were included. Records are listed only from the locations within the present borders of South Korea. A total of 681 species of 258 genera belonging to 46 families were confirmed to exist in Korea. Twenty species, namely Pholcus pojeonensis, Pholcus kwangkyosanensis, Pholcus parkyeonensis, Dysdera crocata, Miagrammopes coreensis, Parasteatoda culicivora, Spheropistha melanosoma, Bathyphantes major, Araneus viperifer, Larinia onoi, Neoscona holmi, Pardosa isago, Pardosa monticola, Trochosa spinipalpis, Anahita samplexa, Cheiracanthium lascivum, Cheiracanthium eutittha, Clubiona japonica, Rhene myunghwani, and Sitticus sinensis, whose distribution or existence within the Korean border were uncertain and did not meet the requirements for valid records were excluded from the present list following critical validation. Sixteen species, namely, Clubiona bakurovi, Clubiona corrugata, Clubiona hummeli, Clubiona komissarovi, Clubiona kulczynskii, Clubiona microsapporensis, Clubiona orientalis, Clubiona paralena, Clubiona propinqua, Clubiona proszynskii, Clubiona sapporensis, Mendoza nobilis, Pseudicius koreanus, Sibianor nigriculus, Sitticus penicilloides, and Yllenus coreanus, which have been described or reported to exist in North Korea were listed separately from the present list. From the zoogeographical distribution, Korean spider fauna was found to be influenced by northern species, including 35 Holarctic and 67 Palearctic species, which account for 14.9% of the total number of species. Korean endemic species include 131 species, which account for 19.2% of the total number. Among neighboring countries, Korean spiders are most similar to those found in Japan. This list (ver. 2010) will be revised periodically after this version.

Bibliographic checklist of Korean spiders (Arachnida: Araneae) ver. 2015

The 2015 version of the bibliographic checklist of Korean spiders from the first checklist by Paik and Kim (1956) is presented, together with a complete bibliography of relevant Korean araneological literature. A total of 620 publications during 1907-2015 including original description on the Korean spiders and records of taxonomic description were critically reviewed. Records only from locations within the present borders of South Korea are listed. A total of 748 spider species of 271 genera belonging to 46 families are confirmed to exist in Korea. Twenty one species, whose distribution or existence within the Korean border are uncertain and lacked valid records, are excluded from the present list pending critical validation. Four spider species endemic to North Korean are listed separately from the present list. One genus, Joopilia Chae and Sohn, 2013 and 2 species, Joopilia jooplis Chae and Sohn, 2013 and Dolomedes jirisanensis Kim and Chae, 2012, which had no designated type species and no diagnosis, are cited as nomina nuda. New synonyms of 15 previously described spider species are proposed. Based on their zoogeographical distribution, the Korean spider fauna was found to be influenced by the northern species, including 36 Holarctic and 72 Palearctic species (14.5% of the total species). Korean endemic species include 160 species (21.5% of the total species). Korean indigenous spiders are also distributed in neighboring countries: 318 species in Russia (42.7%), 460 in China (61.7%), and 488 in Japan (65.5%).

Description of the Female of Clubiona zacharovi Mikhailov, 1991 (Araneae: Clubionidae) from Korea

First known female of the sac spider Clubiona zacharovi Mikhailov, 1991 is described from Korea. This is a rare species inhabiting in the plant litter or under the stone in mountain sites.

Description of Haplodrassus mayumiae Kamura, 2007 and Mangora crescopicta Yin et al., 1990 (Arachnida: Araneae) New to Korean Spider Fauna

Haplodrassus mayumiae Kamura, 2007 of Gnaphosidae and Mangora crescopicta Yin et al., 1990 of Araneidae were newly described and illustrated from Korea.

Comparison of Ground Beetle Communities (Coleoptera: Carabidae) between Coniferous and Deciduous Forests in Agricultural Landscapes

This study was conducted to examine the community structure of ground beetles between coniferous- and deciduous-dominant forest in agricultural landscapes, in Miryang-si, Yeongdong-gun, Icheon-si, and Cheolwon-gun during April to October in 2009. A total of 19 species belonging to 15 genera of 9 subfamilies were identified from 6,253 collected ground beetles. Dominant species from 4 regions were Synuchus nitidus (3,715 individuals, 59.4% of total) and Synuchus cyloderus (1,783 individuals, 28.5%) respectively. Non-metric multidimensional scaling based on Bray-Curtis similarity showed that ground beetle assemblage was not different between forest stands, but it was significantly different among regions. Overall, forest stands of secondary forests may not show a different community structure of ground beetle assemblages in our study. However, monitoring on the ground beetle fauna as well as other arthropods of secondary forests in agricultural landscapes is still important for the management and conservation of biodiversity, because forests provides important habitats for many predatory arthropods, such as ground beetles, spiders and rove beetles.

Four New Species of the Genus Alloclubionoides (Araneae: Agelenidae) from Korea

Four new species of the genus Alloclubionoides collected from mountain litter and hillock litter around the agricultural ecosystem of Korea are described in the present work with appropriate body measurements and morphological illustrations; A. hwaseongensis sp. nov., A. imi sp. nov., A. namhansanensis sp. nov. and A. nasuta sp. nov. Females of A. hwaseongensis sp. nov., A. namhansanensis sp. nov. and A. nasuta sp. nov. can be distinguished based on the epigyne shape and structure of internal genitalia from previously described species. Males of A. imi sp. nov. can also be distinguished based on the shapes of retrolateral tibial apophysis, embolus tip and conductor from previously described species. Also, a key to the Korean Alloclubionoides spiders is provided. Alloclubionoides gajiensis Seo, 2014 is newly synonymized with Alloclubionoides cochlea (Kim et al. 2007).

Spiders from Oksunbong in Chungcheongbuk-do, Korea

Up to date detailed qualitative studies of mountainousspiders in Chungcheong area have not yet been conductedproperly. On a global and regional scale, mountains usual-ly maintain high species richness with some rare speciesbecause they are not much disturbed by human activitycompared to other ecosystems. In view of the growingimportance of distribution data of organisms for conserva-tion at many scale, biota will depend heavily on compileddata including many ecological factors such as time, space,habitat type, community structure, biodiversity, functionalguild and so on. Spiders, one of the main arthropodswhich show high relative abundance, ease of collection,and high biodiversity in habitat preferences and foragingstrategies, allows for effective monitoring of site differ-ences(Yen, 1995). This survey was conducted in Oksun-bong situated in Chungcheongbuk-do, as a serial workto understand spider fauna of Korean mountains throughqualitative monitoring and establishing regional inventory.

Spider Fauna of Island Geojedo (Prov. Gyeongsangnam-do) in Korea

This work was conducted to investigate spider fauna and community structure of Geojedo situated at the southern coast of Gyeongsangnam-do, South Korea. Seventy species of 48 genera belonging to 17 families were identified from 389 collected spiders. Check list of spiders which represent 137 species, 91 genera from 29 families was made from former reports and present work including 4 cosmopolitan species, 6 Holarctic species, 13 Palearctic species and 2 Korean endemic species. Species richness was high in Araneidae (30 species, 21.9%), Salticidae (22 species, 15.8%), Theridiidae (18 species, 12.9%), and Thomisidae and Linyphiidae (10 species, 7.2%) in order. This work might be valuable monitoring to understand the biota of Geojedo and to analyze Korean island ecosystem.
