  • The first zoeal stage of Enosteoides ornata (Stimpson, 1858) is described and illustrated in detail. Its morphological characteristics are compared with those of other known species of the family Porcellanidae. In the family Porcellanidae its diagnostic characteristics are the exopod of an antenna armed with a seta and five spinules and the coxa of the first maxilliped having two setae. The former characteristic can be seen in most of the genus Petrolisthes zoeas, while the latter usually in the genus Pachycheles zoea. The Enosteoides ornata seems to be p1aced intermediately between the genus Pachycheles and the genus Petrolisthes based on the zoeal morphology.

  • Two new marine gastrotrichs of the genus Pseudostomella, P. longifurca and P. koreana, are described from the shallow sublittoral sand bottoms of South Korea. Pseudostomella longifurca n. sp. is characterized by the cuticular armature with tetrancres, five dorsal papillae on the prebuccal apparatus, four dorsolateral adhesive tubes, and elongated pedicle. Pseudostomella koreana n. sp. is distinguished from its congeners by the small body, tetrancres, two pairs of dorsolateral adhesive tubes, and tube-shaped copulatory organ. A brief review of the genus is prepared, with the character comparison table for all congeners currently recognized, and a revised key to the species of Pseudostomella. This is the first record of the genus Pseudostomella from East Asia.

  • A new species, Arca koumaci Lutaenko et Maestrati n. sp. (Bivalvia: Arcidae), is described from New Caledonia. The species is characterized by the small size, the convex shell with a strong posterior umbonal ridge covered by spikes, the widely curved ventral margin, and presence of cancellate sculpture and convergent marginal teeth. Presence of spikes on the posterior ridge is a unique morphological feature recorded for the first time in the genus. It is proposed that the only subgenus, namely Pliocene A. (Arcoptera) Heilprin, 1887, apart from nominative, can be recognized in the genus. Three morphological types are distinguished within the genus based on shell shape and sculpture. Bathymetric analysis shows that representatives of Arca inhabit water depths down to 175 m, and more than half of Recent species were found below 50 m. Types of A. bouvieri P. Fischer, 1874, Arca boucardi Jousseaume, 1894, Arca avellana Lamarck, 1819, and Arca retusa Lamarck, 1819 are illustrated.

  • A marine algal species was collected from the southern coast of Korea. This alga is characterized by a large and cartilaginous thallus, a dichotomous branching pattern, compressed axes, rare proliferations near the apex, and cystocarps protruded toward surface. In a phylogenetic tree based on rbcL sequences, this species nests in the same clade as Neodilsea yendoana as a terminal clade of the genus Neodilsea. The genetic distance between both sequences within the clade was calculated as 0.2% considered to be in the intraspecific range within the genus. Based on the morphological and molecular data obtained in the present study, this Korean species is identified as N. yendoana. This is the first record of the genus Neodilsea and N. yendoana in Korea.

  • The samples were collected at lowland swamps, reservoirs, mountainous wetlands, and sphagnum bogs from 2012 to 2014. The followings were newly recorded in Korea: two species, three varieties, and one form, including six taxa of the genus Cosmarium. The newly recorded Korean species were Cosmarium bioculatum var. hians, C. bireme, C. pseudobiremum, C. nitidulum var. pseudorectangulare, C. trilobulatum f. retusum, and C. trilobulatum var. depressum. The flora of the genus Cosmarium contains 303 taxa in total in Korea. The specimens were cultured and deposited on the algal culture collection of Kyonggi University (ACKU) and National Institute of Botanical Resources (NIBR).

  • Despite the worldwide distributions of genus Lepidepecreum and the previous reports from China and Japan, this genus has not yet been recorded in Korean waters. In this study, Korean materials of lysianassid amphipods are assigned readily to the genus Lepidepecreum and identified as L. vitjazi Gurjanova, 1962 based on the following features: well-developed dorsal keels of the pleonite 3 and urosimite 1; unconcaved palmer margin of ganthopod 1; hooked locking spines of propodus on pereopods 3 and 4; and the shape of coxa 4. We also provide the description and illustrations of this species.

  • The genus Patrinia, belonging to the Valerianaceae family, includes ca. 20 species of herbaceous plants with yellow or white flowers, distributed in Korea, China, Siberia, and Japan. Among them, P. scabiosaefolia (yellow Patrinia), P. saniculaefolia, P. villosa (white Patrinia), and P. rupestris are found in Korea. Several members of this genus have long been used in folk medicine for the treatment of inflammation, wound healing, ascetics, and abdominal pain after childbirth. Thus far, ca. 217 constituents, namely flavonoids, iridoids, triterpenes, saponins, and others have been identified in this genus. Crude extract and isolated compounds have been found to exhibit anticancer, anti-inflammatory, antioxidant, antifungal, antibacterial, cytotoxic activities, lending support to the rationale behind several of its traditional uses. The present review compiles information concerning the phytochemistry and biological activities of Patrinia, with particular emphasis on P. villosa, as studied by our research group.

  • The genus Nippoleucon was newly established within the family Leuconidae and two Hemileucon species, N. hinumensis (Gamo, 1967) and N. enoshimensis (Gamo, 1967), were transferred to this genus. Through examination of the cumacean specimens from the Gwangyang Bay of the Korea Strait, N. hinumensis is recorded as new to Korean fauna. The genus Nippoleucon is reported from Korea for the first time.

  • The genera Dero and Allonais belong to the family Naididae. Most species in the genus Dero have unique morphological characters including a branchial fossa and/or gills at the posterior end of the body. The genus Allonais has no eyes unlike its close relative the genus Nais. Of these genera, one species of Dero, D. obtusa, was recently reported in Korea. However, the genus Allonais has not been recorded in Korea. Here, we report Dero dorsalis Ferroni$\grave{e}$re, 1899 and Allonais pectinata (Stephenson, 1910) with a diagnosis and illustrations.

  • The Palaearctic species of the genus Trathala Cameron are reviewed. Genus Trathala is the third largest group. This genus was described Trathala striata by Cameron for the first time in the world. One hundred one species of this genus have been recorded worldwide. Trathala flavoorbitalis Cameron and Trathala hierochontica (Schmiedeknecht) were recorded from Palaearctic. Here we report three species, Trathala flavoorbitalis Cameron, Trathala hierochontica (Schmiedeknecht) and Trathala striata Cameron, from Palaearctic region. Among them, Trathala striata Cameron is a newly recorded species for the first time from Palaearctic region and South Korea. Redescriptions of Palaearctic Tranthala species with photographs and a key to the Palaearctic Trathala species are provided.
