  • Gammarus gageoensis n. sp., a new species of freshwater gammarid, was collected from Gageodo Island, South Korea. This new species is characterized in terms of its morphology by the flagellum of antenna 2 with calceoli, the pereopods 3 and 4 with numerous long curled setae on the posterior margins, the terminal article of the outer ramus in uropod 3, which is longer than the adjacent spines, and the presence of both rami with long simple setae. The morphological characters of the new species that are different to related species are presented in the text. This paper also compares the new species to related species by the partial sequence of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene. The sequence difference, consisting of a 39-44% difference relative to closely related species, is also large enough to designate this gammarid as a different species from other freshwater gammarid species. This is the first finding of a new species of Korean freshwater gammarid since 1992. Including this new species, a total of 10 species are known to Korea.

  • A new species, Indigofera grandiflora B. Choi et S. Cho, was described from sourthern Korea. The new species is related to I. kirilowii and I. koreana in the Far East. However, the species differs from these two species in having larger flowers and leaflets and hairiness on leaflets. The new species is also allied to I. decora in southest China and Japan, but clearly distinguished from the latter by its larger flowers, shorter inflorescences, and hairiness on leaflets.

  • Seven new species in two genera, Sarcotragus and Bergquistia (Demospongiae: Dictyoceratida: Irciniidae), are described from Jeju Island, Korea. The separation of the two genera was made on basis of morphological evidence in skeletal structure, especially fasciculation of primary fibres and filament thickness. Two new species in the genus Sarcotragus and five new species in the genus Bergquistia are compared with other reported species.

  • A new species of the genus Biemna(Demospongiae: Poecilosclerida: Desmacellidae), Biemna hongdoensis n. sp. was collected from Hongdo Island, Korea by SCUBA diving in 2004. B. hongdoensis n. sp. is closely related to B. megalosigma Hentshel, 1912 in their spicules, but the styles and sigmas of new species are larger than B. megalosigma's and microxeas and raphides of new species are smaller than B. megalosigma's. Also, new species has not spheres. The stubby conulose are distributed throughout the surface of new species.

  • Ten new species of two families (Suberitidae and Polymastidae) are described from Korea. Six new species in Suberitidae: Plicatellopsis ramosa n. sp., Pseudosuberites anheungensis n. sp. P. youngilensis n. sp., Suberites hwasunensis n. sp., S. chujaensis n. sp. and S. rugosa n. sp. are compared with other similar reported species. All new species differ from previously reported species in morphology, texture, color, skeletal structure, and spicule type. Four new species in Polymastidae: Polymastia fistula n. sp., P. sasuensis n. sp., P. viridis n. sp., and Weberella haengwonensis n. sp. are different from previously reported species in the growth form of papillaes and fistules, color and spicule types. For example, Weberella haengwonensis is similar to Weberella verrucosa in shape, but differs based on surface papillaes and spicule sizes.

  • A new species, Monoblastus forsythia sp. nov. is described from South Korea. All specimens of this new species were collected on Forsythia koreana (Nakai). A taxonomic study of South Korean Monoblastus was initiated by Uchida in 1930, and until now four species have been recorded from South Korea. The genus Monoblastus is a Holarctic genus with 31 described species, 14 species are Nearctic, seven are Western Palaearctic region, and nine species occur in Eastern Palaearctic region. In the study, I provide description and photos of both sexes of this new species. Also, modified key to species of the South Korean Monoblastus is provided.

  • 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.
