  • 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 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.

  • Setarches longimanus (Alcock 1894), in the family Scorpaenidae, was collected from Busan and the coastal waters of Jeju Island, Korea, in January and November 2014, respectively. Two specimens are characterized by XI, 10 dorsalfin rays; 19-21 pectoralfin rays; III, 5 anal fin rays; a second preopercular spine much shorter than the first and third; and an interorbital width 11.3 %-11.6 % of the standard length. We also analyzed 587 base pairs of the mitochondrial DNA cytochrome c oxidase subunit I sequences in order to confirm the taxonomic status of the specimen. As a result, the sequences of our specimen almost corresponded to those of Chinese S. longimanus (genetic distance, d = 0.005), but considerably differed from those of S. guentheri (d = 0.120-0.124). We propose the new Korean names "Ma-su-gam-peng-sok" for the genus Setarches, and "Bul-geun-ma-su-gam-peng" for the species S. longimanus.

  • The genus Luidia belongs to the family Luidiidae in the order Paxillosida. It is a common littoral taxon, and the depth range of the Korean fauna is generally 0-100 m. However, specimens of Luidia were collected from Jeju Island in Korea at 150-160 m depth and identified as Luidia sagamina sagamina $D{\ddot{o}}derlein$, 1920. This species is determined by morphological characteristics and mitochondrial cytochrome c oxidase subunit I sequence analysis. Luidia sagamina sagamina is a very rare sea star in worldwide and it only collected previously from Sagami Bay, Japan, and is newly reported in Korea. Four species of Luidia, including L. s. sagamina, are recorded in the Korean fauna.

  • Family Coleophoridae, commonly known as "casebearers", is one of the largest families of Gelechioidea (Lepidoptera), with more than 1,450 described species worldwide, but it has been poorly known in Korea, with only 32 known species of the genus Coleophora Hübner, 1822. Here we present Coleophora fasciella Koo & Baldizzone, sp. nov., a new species to science, and C. mayrella (Hübner, [1813]), an unrecorded species in Korea. Diagnostic characteristics with descriptions of the genitalia are provided with photos of adults, wing venations, and genitalia of both sexes for the species. Mitochondrial cytochrome c oxidase subunit I(COI) barcode sequences for the two species are also provided.

  • 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.

  • In Korean waters, the cirolanid isopod, Eurydice longiantennata Nunomura and Ikehara, 1985 has been reported only from the subtidal zone of Jeju island. We obtained the mitochondrial cytochrome c oxidase subunit I (COI) sequences of this species and determined the DNA barcoding data of E. longiantennata based on a genetic comparison of E. longiantennata and its congeners. The intra-specific genetic distance between the three COI sequences of E. longiantennata ranged from 0 to 0.6%. The inter-specific distances between E. longiantennata and other cirolanid isopods ranged from 24 to 33.2%. In this study, we provided the DNA information of E. longiantennata with a morphological diagnosis and images of the species.

  • Two specimens of Taractes rubescens (family Bramidea) were collected from Busan and Pohang, Korea, between 2015 and 2016. Taractes rubescens was very similar to Taractes asper, but the two species are clearly distinguishable by the number of anal fin rays (21-23 in T. rubescens vs. 25-27 in T. asper) and the presence of a lateral caudal keel (present in T. rubescens vs. absent in T. asper). The mitochondrial DNA cytochrome c oxidase subunit I sequences of the specimens described in this paper perfectly matched those of T. rubescens, but differed from those of T. asper (genetic distance: 6.9%). We use the Korean common name proposed by Kim and Ryu (2017) for T. rubescens, "Geom-eun-sae-da-rae".
