Both the genus Malthacus Kirby and M. angusticollis (Motschulsky) are reported for the first time in Korea. Five North Korean specimens of M. angusticollis were loaned from Hungarian Natural History Museum, Budapest, Hungary and Sungshin Women's University, Seoul, Korea. Here we provide a key to the genus of the Podabrini in Korea and a diagnosis and taxonomic account of the genus Malthacus and M. angusticollis.

A new laophontid copepod species, Apolethon articulatus n. sp., is described from the estuaries and salt marshes in South Korea. Apolethon articulatus is similar to the three congeneric species currently known in sharing the character combination of the elongate first endopodal segment of leg 1 with inner seta and the expansion of second endopodal segments of legs 2-4 with decrease in the number of setae on them. However, A. articulatus differs from them by the separate exopod of female leg 5 and the armature of mandibular palp with 6 setae. Description and taxonomic accounts of the new species are presented herein with detailed illustrations and SEM micrographs. As the true identity of the rarely known genus has not been clarified yet, a revised generic diagnosis is provided with a key to the species hitherto known in the genus.

한국산 모기에 대한 조사연구사업의 일환으로 1387년 6월 경기도 남양주군 광릉에 위치한 임업시험장 일대에서 야외채집을 실시한 결과 미기록종 Aedes bekkui(베꾸숲모기)를 채집하였기에 이를 보고한다. 성충의 특징은 기문하구(subspiracular area)에 작을 강모가 없는 점이고, 유충의 특징은 머리털 4-C와 6-C의 간격이 좁고 5,6-C의 크기와 모양은 서로 대등하며 6,7-C의 간격은 5,6-C의 간격보다 2배이상 넓다는 점이다. 또 꼬리틸 3-X는 단모로 되어 있고 2-X보다 상당히 길다. Tanaka의 검색표에 따르면 Aedes bekkui 성충의 특징은 아속 Edwardsaedes와 일치되지만 유충은 아속 Aedimorphus에 일치된다. 이는 Belkin이 처음 아속 Edwardsaedes를 확립할 때 유일하게 Aedes imprimens를 단모식 표본종(monotypic species)으로 이용하여 그 특징 열거에 있어 너무 단조로 왔기 때문이며 또한 일본에서 A. imprimens가 A. bekkui로 판명되기까지 자충의 특징만이 기록되어 왔기 때문이다. 그러므로 과거 한국에서 보고된 A. imprimens도 일본의 경우와 같이 A. bekkui의 오식종이었을 것으로 생각된다.

The aim of this study is to report monotypic species, Nonparahalosydna pleiolepis(Marenzeller, 1879) for the first time from Korean waters with its DNA barcoding data. We collected individuals of the species from the subtidal zone of southern coast of Korea through scuba diving. To estimate DNA barcoding gap, the pairwise genetic distances were calculated between N. pleiolepis and its congeners (Halosydna brevisetosa Kinberg, 1856 and Lepidonotus squamatus (Linnaeus, 1758)) based on the cytochrome c oxidase subunit I gene (COI). Inter-specific genetic distances ranged from 18.7% to 24.6%, while intra-specific genetic distance within N. pleiolepis ranged from 0.3% to 0.5%. The maximum intra-specific genetic distance among the three species was 1.4%. The morphological diagnosis of N. pleiolepis with a taxonomic note on the species were also provided.

A genuine interstitial cyclopoid species belonging to the genus Psammophilocyclops Fryer, 1956 is recorded from the filtration basin of a water treatment plant, South Korea. The genus Psammophilocyclops is very rarely found, and only three species have been recognized as yet: P. boccaroi Fryer, 1956 from Africa, P. trispinosus Shen et Tai, 1964 and P. bispinosus Shen et Tai, 1964 from China. The present new species differs from the congeneric species by the character combination of 11-segmented antennule in female, four-segmented maxilliped with 2,1,1,2 setation, the spine formula of 3,3,3,3, and setal arrangement of 3,3,5,3 on the distal endopodal segments of legs 1-4. Descriptio and taxonomic accounts of the new species are presented with a revised generic diagnosis and a key to the species hitherto known in the genus.

The species of the genus Athalia Leach from South Korea are reviewed. Six species are listed, one of which is a new record from South Korea (Athalia tanaoserrula Chu and Wang). In South Korean Athalia, we were not able to find any specimens of A. kashmirensis Benson, while many specimens identified as such were a misidentifications of A. tanaoserrula. Therefore, we think that A. kashmirensis should be excluded from the faunal list of South Korea. A key to the species of South Korean Athalia, diagnosis, photographs of the diagnostic characters, distribution and recorded hosts for each species are also provided.

A total of 56 genera and 101 species of the fly family Tephritidae have been previously recorded in Korea. As a result of an ongoing study of this family, I report the following ten additional species new to Korea: Actinoptera montana (Meijere, 1924), Actinoptera reticulata Ito, 1984, Campiglossa luxorientis(Hering, 1940), C. melanochroa (Hering, 1941), C. quadriguttata (Hendel, 1927), C. shensiana (Chen, 1938), Oxyna gansuica Wang, 1998, Tephritis jocaste Hering, 1953, Tephritis okera (Shinji, 1940), and Trupanea guttistella (Hering, 1951). Among the five genera involved here, the genus Actinoptera Rondani, 1871 is recognized for the first time in Korea. Therefore, 57 genera and 111 species are now officially recognized for the Korean tephritid fauna. For each newly recognized Korean species, I provide new Korean name, synonymy, taxonomic diagnosis and color photographs. When possible, I list the host records and discuss their intraspecific variability and sexual dimorphism.

As a result of continuous taxonomic studies on the Korean crabs, Carcinus aestuarii Nardo, 1847 belonging to the superfamily Portunoidea is newly reported from Korean waters. Carcinus aestuarii has characteristics as followings: cardiac, hepartic and brachial regions are divided by deep furrow; shape of three lobes in frontal area is flatter with hairy; inside of carpus is with one sharp tooth; the posterior-lateral margin of the carapace is concave, and so on. The examined specimen doesn't have hairy and bump on outer margin of the chelipeds which differed from the previous description of the specimens collected from Tokyo Bay, Japan. Here, the diagnosis and the picture of Korean specimen is provided. Korean portunoids currently consist of 20 species belonging to 10 genera.

An aegid species, Rocinela niponia Richardson, 1909, is a Far Eastern species known from Korean and Japanese waters. In this study, mitochondrial cytochrome c oxidase subunit I (COI) sequences of R. niponia were determined based on four specimens collected from the subtidal zone of Chujado Island, South Korea. We compared DNA barcoding data of this species with its congeners. As a result, there was no intra-specific genetic distance between the four COI sequences of R. niponia. Inter-specific distances between R. niponia and other five aegid species ranged from 23.8% to 35.6%. Morphological diagnosis and images of R. niponia are also provided as a valuable contribution toward the identification of Rocinela species in further taxonomic and ecological studies.
