Three localities of coastal sand-dunes along the western coastline of Korea: Sindu-ri, Sinhap-ri, and Jaeun-do, were surveyed for the lepidopteran fauna. This survey resulted in the records of five species new to Korea: a species of Cosmopterigidae, Cosmopterix flavidella Kuroko, 2011, based on eight specimens from Sinhap-ri and Jaeun-do; a species of Tortricidae, Noduliferola abstrusa Kuznetzov, 1973, based on five specimens from Sinhap-ri and Jaeun-do; a species of Pyralidae, Maliarpha borealis Sasaki, 2012, based on four specimens from Sindu-ri; and two species of Erebidae, Ectoblemma rosella Sugi, 1982 and Metachrostis miasma (Hampson, 1891), based on one specimen for each from Jaeun-do. Three genera, Noduliferola Kuznetzov, 1973, Maliarpha Ragonot, 1888 and Ectoblemma Sugi, 1982, are introduced for the first time to the Korean fauna. Two species, Noduliferola abstrusa and Maliarpha borealis, are suggested as the indicator species for coastal sand-dunes. The superficial and genital features of the five species found from this study are described and illustrated. A photograph of the female genitalia of Ectoblemma rosella is provided for the first time.

Three new species of the genus Micractinium were collected from five localities on the South Shetland Islands in maritime Antarctica, and their morphological and molecular characteristics were investigated. The vegetative cells are spherical to ellipsoidal and a single chloroplast is parietal with a pyrenoid. Because of their simple morphology, no conspicuous morphological characters of new species were recognized under light microscopy. However, molecular phylogenetic relationships were inferred from the concatenated small subunit rDNA, and internal transcribed spacer (ITS) sequence data indicated that the Antarctic microalgal strains are strongly allied to the well-supported genus Micractinium, including M. pusillum, the type species of the genus, and three other species in the genus. The secondary structure of ITS2 and compensatory base changes were used to identify and describe six Antarctic Micractinium strains. Based on their morphological and molecular characteristics, we characterized three new species of Micractinium: M. simplicissimum sp. nov., M. singularis sp. nov., and M. variabile sp. nov.

Six species of the family Kelleriidae, including four new species, are recorded from tropical waters of the Asia-Pacific, two of them from Phuket Island, Thailand, one each from Bohol Island, Philippines and Phu Quoc Island, Vietnam, and two from Kosrae Island, Micronesia. A new genus Kelleriella is proposed to accomodate one of these new species (Kelleriella quadridens n. sp.). There are three diagnostic features of the new genus: the terminal segment of antenna is armed with one strong claw and six setae, the armature of the maxilliped endopod is reduced, and the third exopodal segment of leg 4 is armed with four spines and five setae. The other three new species are Kelleria latipes n. sp., Kelleria phuketensis n. sp., and Kelleria robusta n. sp. As diagnostic features of these new species, their caudal rami are about 2.5, 3.2, and 1.72 times longer than wide, respectively, the exopod of leg 5 of them is smooth, without any process, about 1.9, 3.7, and 2.9 times longer than wide, respectively, and armed with one spine plus one seta in Kelleria latipes and Kelleria phuketensis or with 2 setae in Kelleria robusta. Additionally, Kelleria javaensis Mulyadi, 2009 is synonymized with Kelleria regalis Gurney, 1927 and Kelleria grandisetiger Kim, 2006 is synonymized with Kelleria andamanensis Sewell, 1949, and both species are redescribed.

This monographic study presents morphological descriptions of eight species of Padina collected from the Visayas and Mindanao regions of southern Philippines, including distributions of each species and a taxonomic key for all the species examined. Of these species, three are new records for the Philippines, namely: P. fernandeziana Skottsberg and Levring, P. jonesii Tsuda and P. moffittiana Abbott and Huisman. One species, P. antillarum (Kützing) Piccone, represents a new nomenclatural record, which is applied to a Philippine species for the first time. Four species previously reported in the Philippines are reconfirmed and described P. australis Hauck, P. minor Yamada, P. boryana Thivy and P. sanctae-crucis Borgesen. All eight species studied have distromatic thalli, except for P. antillarum which is tetrastromatic. Three of these have indusiate sporangia, namely: P. sanctae-crucis, P. moffittianaand P. fernandeziana.

The genus Parorthocladius is a small group among the subfamily Orthocladiinae (Diptera: Chironomidae). A total of ten species of Parorthocladius have been recorded in the world, of which two species were found from Japan, three species from China, and three species from the Russian Far East. Only one species, P. nudipennis is widely distributed in Europe and the Russian Far East. This genus can be distinguished from other genera by the absence of acrostichals on the thorax, wing vein R4+5 ending proximal to the tip of vein M3+4, anal point parallel side, rounded apically. We report four new species of Parorthocladius collected in Korea and described them with illustrations. As a result, fourteen species of Parorthocladius have been recorded in the world.

Three species in the genus Aetea (Bryozoa: Cheilostomata: Aeteidae) are described: Aetea anguina (Linnaeus, 1758), A. ligulata Busk, 1852, and A. truncata (Landsborough, 1852). Aetea ligulata Busk, 1852 and A. truncata (Landsborough, 1852) are new records of Korean bryozoan fauna. Four of the 17 species in the genus Aetea Lamouroux, 1812 are cosmopolitan or widespread. Three of these species (Aetea sica (Couch, 1844) was not observed) are reported in this study.

A new species of the genus Smenospongia (Dictyoceratida, Thorectidae), S. coreana n. sp., is described from Gageodo Island, Korea. This new species is readily distinguished from the other species of Smenospongia by the un-lobated growth forms and un-crowded primary fibres. S. aurea and S. lamellata are no distinction between primary and secondary elements, but this species is easily distinguished from them. The matrix easily derived from the fibres. This species has five sesterterpenes, three scalaranetypes and two linear furanosesterterpenes, in chemical compounds.

The genus Krenosmittia is a small group of Orthocladiinae, containing a total of twenty species in the world. Among them, six species were found in Japan, four species in China, and five species from the Russian Far East. This genus can be distinguished from other Orthocladiinae genera by the eyes bare, absence of acrostichals on thorax, costa strongly extended, anal vein ending proximal to FCu, squama bare, and having a strongly developed virga. We report three new species: K. danyangensis n. sp., K. triangulia n. sp., and K. pseudoannulata. The genus Krenosmittia is the first record in Korea. Line drawings of the diagnostic characters are provided for all the species recognized in this study.

Three new copepod species of Critomolgus are described from the Korean coast of the Sea of Japan. They were found In association with the sea anemones of intertidal and shallow water, one of them from Anthopleura japonica Verrill and the remaining two from Anthopleura midori Uchida and Muramatsu. The descdbed three new oopepods are sympatric and very closely related to one another, though they are easily distinguished from other imown species of the same genus. This is the first record on the sea anemone-associated copepods in the Far East.
