First Report of Stilt Crab Crossotonotus spinipes (Decapoda: Palicoidea: Crossotonotidae) from Korea
Lee, Sang-Kyu,Kim, Sa-Heung,Kim, Won The Korean Society of Systematic Zoology 2010 Korean Journal of Systematic Zoology Special Issue Vol.26 No.3
A stilt crab Crossotonotus spinipes (De Man, 1888) is newly reported from Korean waters as a result of continuous taxonomic studies on crabs. The present specimen has a row of tubercles and a longitudinal lobe with denticles on the dorsal border of the propodus of the chelipeds, and a shorter Pereopod 5. The description and illustration of this species are provided.

The zoeal stages of Pisidia serratifrons are described and illustrated for the first time and its morphological characteristics are compared with those of three known Pisidia species of the family Porcellanidae. The zoea of P. serratifrons differs from those of other Pisidia (P. brasiliensis, P. dispar, and P. dehaanii), by having 11 spinules on the exopod of the antenna. In order to facilitate the study of plankton-collected material, a provisional key is provided for identification of the Korean porcellanid zoeae.
Three Aetideid Species of Copepods (Copepoda: Calanoida: Aetideidae) from East Sea of Korea
Lim, Byung-Jin,Song, Sung-Joon,Min, Gi-Sik The Korean Society of Systematic Zoology 2011 Korean Journal of Systematic Zoology Special Issue Vol.27 No.1
Three aetideid copepods collected from the East Sea of Korea are described: Bradyidius angustus (Tanaka, 1957), Gaetanus minutus (Sars, 1907), and Aetideus acutus Farran, 1929. The former two species are new to the Korean copepod fauna. The sequences of cytochrome c oxidase subunit 1 were determined to be the molecular characteristics of these three species.

Thais Roding, 1798, commonly known as rock-shell, is among the most frequently found gastropod genera worldwide on intertidal rocky shores including those of Japan, China, Taiwan and Korea. This group contains important species in many marine environmental studies but species-level taxonomy of the group is quite complicated due to the morphological variations in shell characters. This study examined the genetic variations and relationships among three Korean Thais species based on the partial nucleotide sequences of mitochondrial cox1 gene fragments. Phylogenetic trees from different analytic methods (maximum parsimony, neighbor-joining, and maximum likelihood) showed that T. bronni and T. luteostoma are closely related, indicating the most recent common ancestry. The low sequence divergence found between T. luteostoma and T. bronni, ranging from 1.53% to 3.19%, also corroborates this idea. Further molecular survey using different molecular marker is required to fully understand a detailed picture of the origin for their low level of interspecific sequence divergence. Sequence comparisons among conspecific individuals revealed extensive sequence variations within the three species with maximum values of 2.43% in T. clavigera and 1.37% in both T. bronni and T. luteostoma. In addition, there is an unexpectedly high level of mitochondrial genotypic diversity within each of the three Korean Thais species. The high genetic diversity revealed in Korean Thais species is likely to reflect genetic diversity introduced from potential source populations with diverse geographic origins, such as Taiwan, Hong Kong, and a variety of different coastal regions in South China and Japan. Additional sequence analysis with comprehensive taxon sampling from unstudied potential source populations will be also needed to address the origin and key factors for the high level of genetic diversity discovered within the three Korean Thais species studied.
A Systematic Study on Syllidae (Annelida, Polychaeta) from the Yellow Sea of Korea
이종위,노분조,Lee, Jong-Wui,Rho, Boon-Jo The Korean Society of Systematic Zoology 1992 Korean Journal of Systematic Zoology Special Issue Vol.3 No.-
본 연구는 1980년 7월부터 1991년 11월까지 서해안의 15개 지소에서 채집된 염주발갯지렁이과(Syllidae) 표본들을 동정 분류한 것으로써, 그 결과 5속 8종이 얻어졌다. 이들 중, Exogone gemmifera, Syllis amica 2종은 한국 미기록종이며, 이들에 관하여는 기재하고 그림을 그렸다. This study on Syllidae was based on the specimens collected from July 1980 to November 1991, at 15 localities in the Yellow Sea of Korea. As a result, eight species of five genera were identified. Of these, two species(Exogone gemmifera and Syllis amica) are newly known from Korean waters. These two species are described with figures.
Two Marine Littoral Species of the Genus Medon (Coleoptera: Staphylinidae: Paederinae) New to Korea
Kim, Tae-Kyu,Cho, Young-Bok,Ahn, Kee-Jeong The Korean Society of Systematic Zoology 2011 Korean Journal of Systematic Zoology Special Issue Vol.27 No.1
The taxonomy of marine littoral species of the genus Medon Stephens in Korea is presented. The genus and two species-Medon prolixus (Sharp) and M. rubeculus Sharp-are identified for the first time in the Korean Peninsula. Redescriptions of M. prolixus and M. rubeculus with an illustration of its habitus and line drawings are provided.
Fish Assemblage Dynamics and Community Analysis in the Han River
Choi, Jun-Kil The Korean Society of Systematic Zoology 2010 Korean Journal of Systematic Zoology Special Issue Vol.26 No.2
A study of Han River fish assemblage dynamics for 4 years was conducted. From April 2005 to August, 2008, fishes inhabiting two sites of Han River were sampled for identification. For further analysis, 40 individuals of the dominant species were sampled monthly from March 2006 to November 2008. The fish assemblage at site 1 was dominated by Zacco platypus (32.69%), while the subdominant species were Acheilognathus yamatsutae (14.4%), Acanthorhodeus gracilis (9.43%), Squalidus japonicus coreanus (6.84%), and Tridentiger brevispinis (5.18%). The most abundant species at site 2 was Korean Chub (Zacco koreanus) with relative abundance of 62.45% and followed by Pungtungia herzi (10.29%), Coreoperca herzi (8.67%), and Coreoleuciscus splendidus (6.82%) as the subdominant species. At both sites, the endemics populations show an increasing pattern during the whole survey period, while the natives were declining in the last two years.
A New Record of Iasis zonaria (Salpida: Salpidae) in Korean Waters

A New Report on Sesarmid Crab Clistocoeloma villosum (Crustacea: Decapoda: Brachyura) from Korea
Lee, Sang-Kyu,Jung, Jong-Woo,Kim, Won The Korean Society of Systematic Zoology 2010 Korean Journal of Systematic Zoology Special Issue Vol.26 No.2
As a result of continuous taxonomic study on crabs, Clistocoeloma villosum (A. Milne-Edwards, 1869) is newly reported from Korean waters. C. villosum has no epibranchial tooth on the carapace, while C. merguiense De Man, 1888, only recorded species of this genus in Korean fauna, has two epibranchial teeth. The description and illustrations of C. villosum are provided herein. Korean Sesarmid crabs now consist of 10 species belonging to six genera.
A Systematic Study on the Asteroidea in Korea I. Species from the South Sea
신숙,Shin, Sook The Korean Society of Systematic Zoology 1992 Animal Systematics, Evolution and Diversity Vol.8 No.2
For the systematic study of Korean Asteroidea the specimens collected from total 69 localities in the South Sea, Korea during the period from April, 1980 to Apirl, 1992 were indentified. As a result, 23 species, 18 genea, 8 families and 5 orders were identified of which two species, Mediaster brachiatus and Stellaster equestris have not been reported in Korea yet. Asterina perctinifera was the commonest species collected from 43 localities of 69 localities. Fifteen species were found in Korea Strait and Cheju Island area, respectively. Fifteen temperate species, 7 tropical species and 3 boreal species were found to be distributed in the South Sea of Korea. The asteroids known so far in Korea tuned out to be 43 species. 1980년 4월부터 1992년 4월까지 우리나라의 남해연안과 여러 도서 지방의 총 69개 지역에서 채집된 해성류를 동정하였다. 그 결과 5목 8과 23종이 밝혀졌고, 이들 중 Mediaster brachiatus와 Stellaster equestris 2종은 한국 미기록종이었으며 Asterina pecitinifera는 43개 지역에서 채집되어 가장 흔한 종이었다. 대한해협과 제주도 해역에는 각각 15종의 해성류가 있었으며 온대종 15종, 열대종 7종, 한대종 3종이 분포하고 있었다. 현재까지 밝혀진 해성류는 43종이 된다.
