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.

In this study, the phylogenetic relationships among the genera Alsidium C. Agardh and Bryothamnion $K{\ddot{u}}tzing$ were investigated. Phylogenetic analyses using the plastid-encoded markers rbcL, psbA, and the mitochondrial barcode region (COI-5P) resolved a well-supported clade that included the species Alsidium corallinum, Bryothamnion seaforthii, and B. triquetrum. Our results indicated that taxonomic recognition of the genus Bryothamnion is not supported and two species of Bryothamnion are reallocated to Alsidium. A reexamination of the morphological definition of Alsidium is provided with an updated diagnosis of the genus and a morphology-based comparison of species that are currently circumscribed under this generic name. Furthermore, we reviewed morphological differences and similarities between Alsidium and the genus Digenea, both belonging to the tribe Alsidieae, discussing the most relevant morphological characters.

Ichneumonidae are well-known parasitoids that attack the larvae or pupae of other insects. This study analyzed whether the abdominal DNA of two ichneumonid wasps, Pimpla disparis and Theronia atalantae gestator, showed the signature of the host species, Ivela auripes. Observations confirmed that these two ichneumonids were the representative parasitoid species growing in the larvae of I. auripes. In addition, sequence analysis showed that the mitochondrial cytochrome oxidase I gene of the host was amplified completely from the DNA extracted from the gut tissues of the ichneumonids. Even after 96 h of adulthood, the host's DNA traces did not disappear and were amplified in many individuals. These results suggest a constructive first step for establishing of a host information bank for ichneumonids in the future.

Spionid polychaete Prionospio kirrae Wilson, 1990 is newly reported from the Yellow Sea in Korea. This species is characterized by four pairs of branchiae, which are apinnate on chaetigers 2-4 and pinnate on chaetiger 5, a caruncle extending to the posterior end of chaetiger 1, the presence of a distinctly high dorsal crest on chaetiger 11, and the presence of tridentate hooded hooks with rounded apical teeth. 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 are determined from Korean specimens.

Four monogonont rotifers, Filinia hofmanni Koste, 1980, Lecane pusilla Harring, 1914, Mikrocodides chlaena (Gosse, 1886), and Proales fallaciosa Wulfert, 1937, were newly recorded in Korea. The genera Mikrocodides Bergendal, 1892 and Proales Gosse, 1886 were recorded for the first time in Korea. Mikrocodides chlaena and Proales fallaciosa were found from soil samples and are both soft-bodied species. Filinia hofmanni has previously been recorded mainly in Europe, and this is its first record in Asia. Lecane pusilla is the 24th lecanid rotifer recorded in Korea, and its morphological characteristics are consistent with previous research of L. pusilla. We have provided the morphological diagnoses of the four Korean specimens in this study, along with the partial sequences of mitochondrial cytochrome c oxidase subunit I(COI) gene of three species.

The genus and species, Diekeana insignis(Gorham), is reported for the first time in Korea. Male adults were collected from Geoje Island and Changwon-si, located in the southern part of South Korea. The species of D. insignis(Gorham) is characterized by the following morphological characteristics: body length about 9.4mm; pronotum with transverse black marking in the middle part; each elytron with seven large black markings; penis long, slightly bent at apical part, truncate at apex; parameres narrow and as long as penis guide; penis guide narrow and pointed at apex. We herein provide habitus photographs, illustrations of morphological characters, male genitalia, and a detailed diagnosis. A partial sequence of the mitochondrial COI gene was obtained and provided mtDNA information for this species.

Two Pseudopolydora polychaetes, P. bassarginensis and P. reticulata, originally described from Peter the Great Bay in Russia and Taiwan, respectively, were recorded firstly in Korea with DNA information. Two species are known to have distinct morphological characteristics that are separated from other Pseudopolydora species. They are characterized by reticulate pigmentations on the dorsal sides of the anterior chaetigers, a longitudinal black band-like pigmentation on the caruncle, and black paired spots on the ventral sides of the anterior chaetigers. These two species can be distinguished morphologically from each other by the length of the caruncle. Methyl green staining pattern of the species is a good method for delimiting Pseudopolydora species. The partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI), 16S ribosomal DNA (16S rDNA), and the nuclear 18S ribosomal DNA (18S rDNA) from Korean specimens of the two species were determined. The morphological descriptions and images of the two Pseudopolydora species are provided.
