  • Recent field and herbarium studies have yielded three vascular plant taxa of the family Poaceae that have been documented in Korea. All of the three species, collected from Jeolla-do and adjacent areas, were introduced and naturalized. Three species are identified as Vulpia bromoides (L.) Gray, Agrostis capillaris L. and Eragrostis pectinacea (Michx.) Nees. We provide the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa are also provided.

  • Twelve species of siphonostomatoid copepods mainly associated with marine invertebrates are recorded from Korean waters. Nine species are new to science: Arctopontius minutus n. sp., A. adelphus n. sp, and Dyspontius alatus n. sp. in the family Artotrogidae; Asterocheres horridus n. sp., A. cuspis n. sp., A. quadridens n. sp., Scottocheres mipoensis n. sp., Asteropontoides acutirostris n. sp. and Callomyzon macrocephalus n. gen. n. sp. in the family Asterocheridae. The new genus Callomyzon is distinguished from other genera in the family by having six setae on the third endopodal segment of leg 3, four spines and three setae on the third exopodal segment of leg 4 and three setae on the third endopodal segment of leg 4. Three new records of Korea, Asterocheres lilljeborgi Boeck, 1859 and A. simulans (T. Scott, 1898) in the Asterocheridae, and Parartotrogus arcticus T. and A. Scott, 1901 in the Cancerillidae are redescribed as the circum-Arctic species.

  • This study aims to investigate the freshwater bryozoans of Jeju Island off the Korean Peninsula for the first time. To date, twelve species has been reported from the mainland of Korea. However, no study of freshwater bryozoans has ever been conducted on Korean islands including Jeju Island, which is the largest island in Korea. Five species in three genera Fredericella, Plumatella and Stephanella, from Jeju Island are described. Of which, three species, Fredericella indica, Plumatella mukaii and P. rugosa, are new records of Korean bryozoan fauna. As a result of this study, the number of identified Korean freshwater bryozoans is now 15 species, including 12 phylactolaemates and three gymnolaemates.

  • Three species of pelagic sergestid shrimps, Deosergestes seminudus (Hansen, 1919), Sergia lucens (Hansen, 1922) and S. talismani (Barnard, 1947), were identified based on collections by the National Fisheries Research and Development Institute from the Korean coast of the Yellow Sea between 2003 and 2011. They are herein reported for the first time from the Yellow Sea. Morphological descriptions and illustrations with color photographs of all species are also given. With the addition of these species, the family Sergestidae in the Korean waters now comprises five species belonging to three genera. Finally, a key to the Korean genus and species of the family Sergestidae is presented.

  • Three species of the genus Dohrniphora, viz., D. cornuta, D. malaysiae, and D. prescherweberae were newly recorded from Korea. These newly recorded species can be easily identified by the characteristic that inner face of male hind femur equipped with a group of peg-like stout setae on basal sensory area. Peg-like setae are arranged perpendicularly in D. cornuta whereas linear in D. malaysiae and somewhat arched in D. prescherweberae. Also, concave area near the peg-like setae is also well developed in male which is smooth in D. cornuta, on the other hand, there is well developed distal carina in D. malaysiae and with groups of microtrichia in D. prescherweberae. In this study, detailed descriptions with photographs of three newly recorded species and a key to males of all Korean Dohrniphora species are provided.

  • A new genus and two new species of Bathynellacea are described from California in USA. Califobathynella, a new genus, belongs to the subfamily Leptobathynellinae, and is closely related to the genera Parvulobathynella and Leptobathynella but differs from them with respect to labrum, maxillule, maxilla, and male thoracopod VIII. Based on the detailed structure of mouthparts, the phylogenetic relationship of three genera are discussed. The phlogenetic age of the stem species of three genera are estimated at the late Jurassic, based on their phylogenetic relationship and distribution pattern. Two new species, C. noodti and C. teucherti differ from each other in the structure of labrum.

  • Three species of Ellobiid molluscs collected from Korea were identified as Auriculastra duplicata (Pfeffer, 1854), Laemodonta siamensis (Morelete, 1875) and Melampus (Pira) flavus (Gmelin, 1791). This is the first record from the Korea, providing a description of the species with illustration for the shell morphology. Including the new recorded in this study, the family Ellobiidae contained six genera and 13 species in the Korea.

  • We report three new records Korean marine gastropods. The new record species are Hipponix acuta, Lyncina (Ponda) carneola, and Velutina (Velutella) plicatilis cryptospira. As a result, the family Hipponicidae in Korea turned out to be 5 species of 4 genera, Cypraeidae are 14 species of 8 genera, and Velutinidae are 7 species of 3 genera, respectively.
