According to zoogeographic analysis, distribution types of Korean species of the subfamily Tryphoninae are as follows; Holarctic species (9.6%), Transpalearctic (38.4%), Transpalearctic-Oriental (8.2%), Eastern Palearctic (Trans-Far East Asia)-Oriental (4.1 %), Eastern Palearctic (17.8%) and Endemic (21.9%). Because of large numbers of palearctic and endemic species, we believe that the Korean Tryphoninae may have originated from northern hemisphere. The oldest fossil species of the Tryphoninae are the Catachoru rninor Townes and Urotryphon pusillus Townes in Creataceous amber from the peninsula Taimyr, Siberia. The world-wide distribution of the Tryphoninae appears to coincide with the continental movement.

A taxonomic study of the Palearctic species of the genus Brachyserphus is presented. Two species are newly described as B. acuticaudatus sp. n. and B. semipunctatus sp. n. from South Korea and the Russian Far East. B. striatopropodeatus (Kolyada 1997 syn. n.) is synonymized under B. lucens (Provancher 1883) and a key to the Palearctic species is provided.

We investigated cladoceran fauna from 71 study areas in South Korea. Sixty-two taxa were found, of which there were 30 planktonic and 25 littoral-benthic cladoceran species. In the present study, taxa of cladocera were identified by biographical traits. Species endemic to the Far East were found in the northernmost areas of South Korea, whereas Palearctic species were found in the southernmost areas. Generally, coexistence of cladoceran species in northern and southern areas was observed, implying possible faunistic complexes of cladocera in various areas of South Korea. We believe that further studies conducted in different habitats will greatly expand our knowledge of the biodiversity of cladocera in South Korea.

The characteristics of insect communities in specific localities reflect climatic and environmental status and change. We investigated the description pattern of new insect species by reviewing announcements of new or newly recorded insects in Korea published in five systematic journals between 1999 and 2009: Entomological Research (1999-2009), Insect Koreana (1999-2003), Journal of Asia-Pacific Entomology (1999-2009), Korean Journal of Applied Entomology (1999-2009), and Korean Journal of Systematic Zoology (1999-2009). A total of 757 new species were reported in 299 research papers. More than 85% of the newly described or reported species belonged to four orders: Coleoptera (225 species), Lepidoptera (202 species), Hymenoptera (141 species), and Diptera (82 species). The number of new species fluctuated from year to year, and a few major authors described most species. The graph of the cumulative number of species described in Korea was not asymptotic. We also examined the decadal trends in the proportion of species according to their biogeographical origin. The numbers of northern (Palearctic and Nearctic) and southern (Oriental) species recorded in Korea between 1999 and 2009 were increasing mainly due to the recent taxonomic research environment. It is also possible that recent climatic change induces new migrants toKorea from more southern parts of Oriental region, but more information is needed to confirm this hypothesis.

A Korean Cheiracanthium erraticum (Walckenaer, 1802) is first described with detailed illustrations, leg spination, trichobothrium patterns and SEM photographs of male palp and female epigynum. Two species, C. lascivum Karsch, 1879 and C. eutittha Boesenberg & Strand, 1906 are excluded from Korean fauna. A map showing distribution of species and a key to the species of genus Cheiracanthium from Korea are provided.

Three species of the linyphiid genus Walckenaeria, Walckenaeria chikunii Saito and Ono, 2001, Walckenaeria furcillata (Menge, 1869), and Walckenaeria ichifusaensis Saito and Ono, 2001, are reported new to the Korean spider fauna. W. furcillata is widely distributed throughout the Palearctic region, but W. chikunii and W. ichifusaensis are only known from their type localities in Japan. Photographs and illustrations of the diagnostic characters are provided.

Spider fauna of Mt. Yongmunsan located in Yangpyeong-gun, Gyeonggi-do, was surveyed from April to October in 1996. A total of 75 species of 51 genera in 22 families from 996 individuals of spiders were identified. Species richness of each family, there were 17 Araneid species (22.7%), followed by each of the 7 Thomisid and Tetragnathid species (9.3%), 6 Salticid species (8.0%), and 5 Lycosid species (6.7%). Zoogeographically, spider fauna of Mt. Yongmunsan represented 1 cosmopolitan species (1.3%), 2 holarctic region species (2.6%), and 9 palearctic region species (12.0%), and 4 Korean endemic species (4.0%). Thus it is suggested that spider fauna of Mt. Yongmunsan was under northern regional influence.

Sciaria thoracica Matsumura belonging to the family Sciaridae is recorded from Korea for the first time. This species is a conspicuous species having the rufous thorax in Palearctic region. The morphological diagnosis and photos of adult, and the result of DNA barcoding inferred from the Korean and the Japanese populations of S. thoracica are provided.

Spider fauna of Oksunbong located in Jecheon City, Chungcheongbuk-do, was surveyed provisionally from May to September in 1998. A total of 58 species of 40 genera in 18 families from 301 individuals of spiders were identified. Species richness of each family, there were 10 Araneid species (17.2%), followed by 9 Theridiid species (15.5%), and 8 Tetergnathid speices (13.8%). Zoogeographically, spider fauna of Oksunbong represented 1 cosmopolitan species (1.7%), 2 holarctic region species (3.4%), and 7 palearctic region species (12.1%). However, Korean endemic species were not collected during this survey. Thus it is suggested that spider fauna of Oksunbong was under northern regional influence.
