Acrobeloides nanus (de Man, 1880) Anderson, 1968 belonging to the family Cephalobidae Filpijev, 1934 (Cephalobomorpha) is newly reported from South Korea. This species is distinguished from other Acrobeloides species by its low and blunt labial probolae, five lateral incisures with middle incisure extending to the tail tip, and bluntly rounded tail. In this study, details of morphological characters of A. nanus is described and illustrated based on optical and scanning electron microscopy. In addition, molecular sequence data of the D2-D3 region of 28S rDNA, 18S rDNA and mitochondria DNA cox1 region from this species are provided as DNA barcode sequences.

The present census on freshwater bryozoans in the Han River, Geum River and in lentic water bodies in Gangwon Province revealed three gymnolaemate species. Two of them-Hislopia prolixa Hirose and Mawatari, 2011 and Victorella pavida Saville Kent, 1870 were recorded for the first time from South Korea. Paludicella articulata (Ehrenberg, 1831), on the other hand, had already been documented from a few sites since 1941. The bryozoans, all belonging to the order of Ctenostomata, were found on a variety of substrates in freshwater (H. prolixa and P. articulata) and brackish habitats (V. pavida). Hislopia prolixa had recently been established as a new species and this is the first record for an occurrence outside of Japan, where it had been newly described from Lake Biwa and nearby satellite lakes.

The Ministry of Environment of South Korea has launched its plan to establish the National Ecological Institute. An International Symposium and Workshop was held at Ewha Womans University in Seoul on Thursday, 30 September 2010, to strengthen international cooperation, networking and partnerships for the conservation of biodiversity. This symposium was attended by experts of many major institutions for biodiversity conservation from South Korea and overseas. At the symposium and workshop preceded by a keynote speech by the renowned primatologist and conservation biologist Jane Goodall the participants discussed a wide range of topics including "biodiversity conservation: in situ and ex situ approaches", "conservation of species diversity and ecosystem management", and "international cooperation for biodiversity conservation and research". As a basis for future discussions, this article summarizes how the National Ecological Institute might contribute most effectively to public life and environmental management in South Korea and worldwide. It addresses the following issues: governance and funding, synergies within Korea, participation in international networks, external advice, a broad view of ecological issues, research agenda, building on identity, public outreach, and training the next generation of scientists.

The genus Callochiton Gray, 1847 is small to medium sized chiton (up to $55{\times}36mm$ in size) and includes approximately 30 species worldwide, most of which are found on hard substrata in subtidal zone. To date, only three species of Callochiton Gray, 1847 have been reported in Japan. In this study, we found C. foveolatus(Is. Taki, 1938) as first record of the family Callochitonidae Plate, 1901 in Korea and its morphological features were described and compared with other northwestern Pacific species. In addition, the partial fragment of mitochondrial DNA cytochrome c oxidase subunit I sequences of C. foveolatus was determined as DNA barcoding record and compared with other congeneric species.

Taxonomic study for the comatulid crinoids collected from the Korea Strait and Jeju Island was conducted. Two species of comatulids, Captoptometra rubroflava belongs to the family Zygometridae and Gephyrometra versicolor belongs to the family Calometridae, were identified and both of them were turned out to be new to the Korean fauna. The family Zygometridae is newly reported in Korea.

Protochitonidae Ashby, 1925 is a family of small to medium sized chitons that includes a single fossil genus and two extant genera. Of the two extant genera, Deshayesiella Carpenter in Dall, 1879 contains 5 described species. Although most Deshayesiella species are known to be found in deep sea habitats(over 100 m), D. curvata (Carpenter in Pilsbry, 1892) is found from shallow waters(1-20 m). In this study, we provide details of microstructure of shell and radula characters using scanning electron microscopy and morphological features of D. curvata, and its partial sequence of mitochondrial DNA cox1 gene as DNA barcode sequence. In addition, we compare morphological differences of D. curvata from other congeneric species.

An epialtid spider crab, Naxioides robillardi (Miers, 1882), is known as widely distributed in Indo-West Pacific region include Japanese waters. Four specimens of epialtid crabs were collected from adjacent waters of Jejudo Island and identified as N. robillardi. This species can be grouped into two forms such as N. robillardi form typical and N. robillardi form mammillata according to morphological features of carapace, gastric spine, and chela. Morphological characters of all Korean specimens well agree with the form mammillata in general. In this paper, morphological diagnosis and illustrations of newly collected N. robillardi are provided. DNA barcode sequence of COI region is also determined for the first time.

A parasquillid stomatopod, Faughnia haani(Holthuis, 1959), collected from Jeju Island, is reported for the first time in Korea. This species is characterized by the presence of obtuse anterolateral angles of carapace, median and three pairs of longitudinal carinae on telson, and crenulate inner margin of uropodal protopod. In this paper, a detailed description and illustrations are provided. As a result of this study, the geographical distribution of the present species is extended and 15 species of stomatopods including this species are now recorded in Korean fauna. The specimen examined herein was deposited in the National Institute of Biological Resources(NIBR).

A squillid stomatopod, Oratosquilla fabricii, collected from Jindo Island, is reported for the first time in Korea. The family Squillidae differs from other families by the presence of more than four intermediate denticles of telson. This species is distinguished from O. oratoria, another Oratosquilla species recorded in Korea, by the presence of an armed submedian carinae on the fourth abdominal somite and dark patches on the second abdominal somite. In the present study, detailed descriptions and illustrations of O. fabricii are provided. A key to the species of Korean Oratosquilla species is also presented. With this new record, the number of stomatopod species in the Korean fauna has increased to 16.

Polygordiidae is recorded as a new record in the Korean fauna. Twenty-three specimens of Polygordius pacificus were collected from the low intertidal zone with coarse sandy bottom on the eastern coasts of Korea. Morphologically, there was no doubt that the specimens are close to the holotype of P. pacificus, particularly due to the presence of elongated and longitudinal pygidial glands, and the length to width ratio. The prostomium of the Korean specimens have a rounded shape that is similar to subsequent research using scanning electron microscope. The DNA sequence comparison of the mitochondrial cytochrome c oxidase subunit I (COI) between Korean and Japanese population supports the identification of present specimens.
