Four feather mites, Alloptes(Apodalloptes) orthogramme Gaud and Mouchet, 1957, Alloptes(Conuralloptes) limosae Dubinin, 1951, Alloptes (C.) procerus Gaud, 1972 and Alloptes (Sternalloptes) fauri Gaud, 1957 are reported for the first time in South Korea. These specimens were collected from four charadriiform bird species: Actitis hypoleucos, Larus crassirostris, Limosa limosa, and Numenius phaeopus. The family Alloptidae Gaud, 1957 and a genus Alloptes Canestrini, 1879 are newly added to the invertebrate fauna of South Korea as well. Here, we provide the morphological description and illustrations based on the present specimens. Additionally, partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) were newly-generated for using as DNA barcodes.

재첩은 하구생태계에 서식하는 종으로, 우리나라에는 섬진강 하구에서 가장 많이 분포하는 것으로 알려져 있다. 섬진강 하구에 서식하는 재첩은 담수와 해수생태계의 변화를 잘 반영하는 종이다. 재첩은 외부형태만으로는 종 동정이 어려운 분류군에 속한다. 본 연구에서는 섬진강 서식 재첩의 종 동정을 위해 형태적 관찰뿐만 아니라 미토콘드리아 DNA의 COI 유전자 기반 DNA 바코딩을 통해 분석하였다. 그 결과 재첩 간 다른 두 종을 확인하였으며, COI 염기서열의 다중배열 분석결과 약 98%의 높은 상동성을 보였다. 재첩과 내 다양한 종들과 계통수 분석으로 계통유 전학적 위치를 확인한 결과, 본 연구에서 사용한 재첩은 C. japonica, C. fluminea와 하나의 계통군으로 묶여졌고 진화적 거리는 0.003 이하로 나타났다. 또한 재첩속인 C. leana와 0.089, C. fluminalis와 0.096으로, 재첩과 내 3종과는 약 0.2로 C. japonica에 비해 상대적으로 진화적 거리가 먼 것으로 나타났다. 계통유전학적 분석을 통해 본 연구에서 사용한 재첩은 C. japonica이고, 그중 한 개체가 C. fluminea인 것으로 확인되었다. 이러한 연구 결과는 DNA 바코딩을 이용한 섬진강 하류 지역에 서식하는 재첩의 COI 시컨스를 통해 계통유전학적 정보를 제공하여 형태학적 분석에 어려움이 있는 종에 대한 중요한 자료로 활용될 것이다.

Two feather mites, Zachvatkinia larica Mironov, 1989 and Ardeacarus ardeae (Canestrini, 1878) are reported for the first time in Korea. Specimens of Z. larica and A. ardeae were collected from the blacktailed gull Larus crassirostris and little egret Egretta garzetta, respectively. The genera Zachvatkinia Dubinin, 1949 and Ardeacarus Dubinin, 1951 are new to this country. Here, we provided morphological descriptions and illustrations of these two species. Additionally, we provide the partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) as DNA barcode markers.

Four feather mite species, Grallobia fulicae (Trouessart, 1885), Grallobia gallinulae Gaud, 1968, Grallolichus proctogamus (Trouessart, 1885) and Megniniella gallinulae (Buchholz, 1869), previously unrecorded in South Korea are reported. Specimens of Grallobia fulicae and Grallolichus proctogamus were collected from the eurasian coot, Fulica atra in Cheongju-si. Grallobia gallinulae and M. gallinulae were found on the common moorhen, Gallinula chloropus in Yesan-gun. The genera Grallobia Hull, 1934, Grallolichus Gaud, 1960 and Megniniella Gaud, 1958 are new records for South Korea. Here, we provide illustrations and morphological descriptions of these four feather mite species as well as the partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) as DNA barcodes.

Two feather mites, Scutomegninia phalacrocoracis Dubinin and Dubinina, 1940 and Ptiloxenus major ($M{\acute{e}}gnin$ and Trouessart, 1884) are reported for the first time in Korea. Specimens of S. phalacrocoracis and P. major were collected from the great cormorant, Phalacrocorax carbo and great crested grebe, Podiceps cristatus, respectively. The genera Scutomegninia Dubinin, 1951 and Ptiloxenus Hull, 1934 are also new reports for South Korea. Here, we provide morphological descriptions and illustrations of these two species. Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) as DNA barcodes.

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.

Scolelepis (Parascolelepis) papillosa (Okuda, 1937), originally described from a single incomplete individual from Jeju Island in Korea, was collected from the intertidal sandflats of Soan Island (Jeollanam-do province) in Korea. The examined specimens of S. (P.) papillosa agree well with the original description in having the papillae on the basal sheath of the palps, presence of occipital antenna, absence of notochaetae in chaetiger 1, branchiae completely fused with notopodial postchaetal lamellae at the anterior chaetigers, and neuropodial hooded hooks appearing from chaetiger 16. In this study, the sequences of partial mitochondrial cytochrome c oxidase subunit I (COI), 16S ribosomal DNA (16S rDNA), and the nuclear 18S ribosomal DNA (18S rDNA) of the species were determined. We also provide the detailed description and illustrations on this species based on the complete specimens newly collected in this study.

Feather mites comprise two superfamilies(Analgoidea and Pterolichoidea) and are highly specialized ectosymbionts of birds. To date, this group contains more than 2,500 species worldwide. Fifty-five feather mite species have been reported in Korea, and only one species of genus Alloptes has been recorded from black-tailed godwit Limosa limosa. Three new records of feather mites from the L. limosa in Korea are added in this study: Avenzoaria punctata Gaud, 1972, Bregetovia limosae (Buchholz, 1869), and Montchadskiana buchholzi (Canestrini, 1878). The genus Bregetovia Dubinin, 1951 is also new report for this country. In this paper, we provide the morphological descriptions and illustrations based on the present specimens. Additionally, we determined partial sequences of the mitochondrial cytochrome c oxidase subunit I(COI) from three feather mites as DNA barcodes.

Jesogammarus (Jesogammarus) hinumensis Morino, 1993 was discovered firstly from a brackish water region in Jeju Island, Korea. To identification of the specimens we conducted both of morphological and molecular analyses. This species is characterized by having large eyes and a robust seta on the mandibular palp article 1. The morphology of this Korean specimens was well matched with the original description without variation. The mitochondrial cytochrome c oxidase subunit I(COI) sequences of the present specimens were also completely identical to the sequences of J. (J.) hinumensis collected from the type locality of the species. Thus, we concluded that the Jesogammarus species from Jeju Island is J.(J.) hinumensis, based on both morphological and molecular data.

The brittle star, Amphistigma minuta H.L. Clark, 1938, was collected from Munseom Island, Jeju-do, Korea, by SCUBA diving. This species has distinct morphological features, as follows: a small disk with large papillae on the disk margin; slender arms and four arm spines at proximal; and oral parts the same as those of the genus Amphipholis. Additionally, we obtained partial sequences of the cytochrome c oxidase subunit I gene (COI) (513 bp) and compared them with sequences from Australian A. minuta and 13 other species of Amphiuridae. As a result, intraspecific pairwise distance was 0.4% between two Korean individuals and intraspecific distance between the Australian and the Korean populations was 2.6-2.8%, which indicates they should be considered as the same species. Ultimately, 15 species of the family Amphiuridae have currently been recorded in Korea, including A. minuta.
