Two new records of Scleroderma species from South Korea are described here. Comprehensive taxonomic studies of Scleroderma specimens were conducted at the Korea National Arboretum. Based on morphological and molecular data (fungal barcode sequences), two new records (S. laeve and S. nastii) were confirmed. Herein, morphological descriptions, including Scanning Electron Microscope (SEM) images of basidiospore ornamentation, and a taxonomic key of Korean Scleroderma species are provided.

We conducted a taxonomic study of bdelloid rotifers found from terrestrial habitats such as mosses, leaf litter and soil at four different locations in Korea. The study resulted in four new Korean records belonging to two genera in two families, Habrotrochidae and Philodinidae, of bdelloid rotifers: Habrotrocha soror Donner, 1950; H. thienemanni rubella Donner, 1951; H. valida Milne, 1916 and Philodina nitida nitida Milne, 1916. These new Korean records are rare and have very limited distributions. Habrotrocha thienemanni rubella and H. valida were not found again after their original descriptions until the present study. The present study is the third record for both H. soror and P. nitida nitida. All these four new Korean records are new to Asian fauna as well. Here, diagnostic characteristics and photomicrographs are provided for each new Korean record. In addition, a partial sequence of mitochondrial cytochrome c oxidase subunit 1 gene (mtCOX1) for P. nitida nitida is presented.

The Korean Olethreutinae comprises 277 species. In this study, two species of Olethreutinae: Hedya corni Oku, 1974 and Epinotia salicicolana Kuznetzov, 1968, are reported for the first time from Korea. Our records of Hedya corni are based on three specimens in both sexes from Islands Bogildo and Geojedo. The Korean record of Epinotia salicicolana is based on one male specimen from Muan-gun. The present records of Hedya corni represent the first occurrence out of Japan. Hedya corni is similar to Hedya inornata (Walsingham) but differs from the latter in having the reddish brown forewings. Epinotia salicicolana is similar to Epinotia solandriana (Linnaeus) but differs from the latter in having the smaller dorsal patch on the forewing. Habitus and genitalia of the two olethreutine species are illustrated and briefly described. Their bionomics and distribution are summarized. With our new records, the species numbers of the Korean Hedya and Epinotia are increased to 11 and 23, respectively.

Through the collection of herbarium specimens in Bhutan over the years, new plant species are discovered nearly annually. Thus, this paper reports two new genera and 19 new records of flowering plant species from Bhutan. The new genera include Eurycorymbus of the family Sapindaceae and Homalium of the family Salicaceae. The new records of plant species are Eranthemum erythrochilum (Acanthaceae), Hemidesmus indicus (Apocynaceae), Ilex umbellulata (Aquifoliaceae), Canarium strictum (Burseraceae), Ehretia acuminate (Boraginaceae), Vaccinium sikkimense (Ericaceae), Nothapodytes foetida (Icacinaceae), Machilus edulis (Lauraceae), Grewia asiatica (Malvaceae), Hibiscus fragrans (Malvaceae), Cipadessa baccifera (Meliaceae), Baccaurea javanica (Phyllanthaceae), Canthiumera glabra (Rubiaceae), Homalium napaulense (Salicaceae), Eurycorymbus cavaleriei (Sapindaceae), Acmella radicans (Asteraceae), Silene latifolia (Caryophyllaceae), Cleome rutidosperma (Cleomaceae), and Cuphea carthagenensis (Lythraceae). Morphological determinations of the genera and species were carried out at the National Herbarium (THIM) of the National Biodiversity Centre of Bhutan. Brief descriptions of the species, phenology, and photo plates are provided in this annotated checklist.

A taxonomic study on bdelloid rotifers collected from mosses and/or leaf litter at four different locations in Korea resulted in five new Korean records and a new species, Philodina wonkimi n. sp. Philodina wonkimi n. sp. is easily distinguished from its congeners by the very long antenna which is much longer than the height of the pseudosegment carrying a dorsal antenna in creeping. Among the five new Korean records, two species- and two subspecies-level taxa are new to Asia as well. Adineta rhomboidea Bērzinš, 1950 has been reported from only three European countries including the type locality, and is recorded outside Europe for the first time. Present study is the fourth record for Philodina eurystephana Schulte, 1954. In addition, a partial sequence of mitochondrial cytochrome c oxidase subunit I gene (mtCOX1) for P. wonkimi n. sp. is provided here.

Two trochid shells of the genus Ginebis, G. crumpii(Pilsbry, 1893) and the genus Enida, E. japonica A. Adams, 1860, collected from the coast of Jeju Island in Korea are reported. Ginebis crumpii and Enida japonica are closely related to Calliostoma Swainson, but can be differentiated by the features of the aperture and umbilicus. These species are a new records to the Korean Molluscan fauna. At present, G. crumpii and E. japonica are the only species of the represented in Korean water. Including the new records in this study, the family Trichidae contains 30 genera and 57 species in Korean water.

Two new species, Pentathyone kojinensis n. sp. and Pseudocnus pawsoni n. sp. belonging to the families Sclerodactylidae and Cucumariidae are described. In addition, four species, Thyone bicornis, Thyone fusus chinensis, Thyone micra, and Molpadia changi, are reported as new records from Korea. Pentathyone kojinensis n. sp. closely resembles Cucumaria mirabilis Theel and C. constrica Ohshima in ossicle form, but the latter two species are clearly distinguished from the new species in having the posterior processes of the calcareous ring in several fragments, rather than stout and entire. Pseudocnus pawsoni n. sp. is similar to Cucumaria koraeensis Ostergren in general features and ossicle morphology though it has not biscuit-shaped plates. However, Cucumaria koraeensis has ten tentacles of the same size, unlike Pseudocnus pawsoni n. sp. in which the two ventral tentacles are much smaller than the remaining eight.

Two new yeast records, Cryptococcus adeliensis YJ19-2 and Cryptococcus uzbekistanensis YJ10-4 were screened from 60 yeasts strains that were isolated and identified from wild flowers in Yokjido, Gyeongsangnam-do, Korea. The morphological and cultural characteristics of the newly recorded yeasts and the physiological functionalities of the supernatants and cell-free extracts obtained from their cultures were investigated. The two newly recorded yeasts did not form ascospores and pseudomycelia. They also grew well in yeast extract-peptone-dextrose broth. C. uzbekistanensis YJ10-4 grew in a vitamin-free medium and was also tolerant to sugar and salt. Antihypertensive angiotensin I-converting enzyme inhibitory activity of the supernatant from C. adeliensis YJ19-2 was high (71.8%) and its cell-free extract also showed very high (81.2%) antidiabetic $\acute{a}$-glucosidase inhibitory activity.

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.
