Two isopods, Elaphognathia lucanoides Monod, 1926 and Limnoria saseboensis Menzies, 1957, are newly recorded in Korean fauna. Elaphognathia lucanoides can be distinguished from its congeners by the following characteristics combined: the cephalon is strongly excavated on the anterior margin; the paraocular ornamentation is forming a ridge distinctly; and the mandible is longer than cephalon. Limnoria saseboensis differs from the related species by the following features: pleonite 5 has two parallel longitudinal carinae; the pleotelson has one or two pairs of tubercles and two carinae; and the tubercles are present on the posterior margin of the pleotelson. In this paper, detailed descriptions and figures of these two species are provided.

In the flora of Korea, Carex L. is one of the most species-rich genera. Among nearly 157 Carex taxa, less than 30 have had chromosome numbers reported. We report the meiotic chromosome numbers of eight Carex taxa from Korean populations, which include the first count for C. accrescens Ohwi (n = 37_II) and the first chromosome investigations of Korea populations for three taxa: C. bostrychostigma Maxim. (n = 22_II), C. lanceolata Boott (n = 36_II), and C. paxii Kuk. (n = 38_II). In most species, chromosome counts observed in the study are included in the variation ranges of previous chromosome numbers. However, C. bostrychostigma Maxim. (n = 22_II) and C. planiculmis Kom. (n = 29_II) are assigned new chromosome numbers. Carex is known to have holocentric chromosomes, lacking visible primary constrictions and exhibiting great variance in its chromosome number. Further investigations of the diversity of Carex chromosomes will provide basic information with which to understand the high species diversity of the genus.

Members of this family Sciomyzidae are known as marsh flies and snail-killing flies because most of the known larvae are obligate predators of Mollusca, especially freshwater and terrestrial Gastropoda. Most species are found in the shallow ephemeral aquatic habitats with rich organic substrates, such as the hard-water streams, small ponds and lakes in mountain valleys. To date, a total of 8 marsh fly species in 4 genera have been known in Korea. During a taxonomic survey of the family Sciomyzidae in Korea, the authors have found the genus Ditaeniella Sack, 1939; thus, it was discovered for the first time in Korea. This genus can be distinguished by the other related taxa with hairs over much of the mesopleuri, hairs on the prosternum and one orbital seta. In addition, the nominate species, Ditaeniella grisescens Meigen, 1830 was also firstly recoded in the Korean fauna.

Psalidoremus is one of the subgenus which consists of five species and eleven subspecies through Taiwan, Japan, Korea and north eastern part of China which present strong endemism to their distribution. While most of advance studies focus on the new species or subspecies from this taxon, this paper suggests paleogeographical assumption and hypothesis of how they diverged from common ancestors. Phylogeographical patterns illustrated by the distribution of five species, which including Prosopocoilus inclinatus, Prosopocoilus hachijoensis, Prosopocoilus dissimilis, Prospocoilus pseudodissimilis, Prosopocoilus motschulskii respectively, has been assessed in this research. Speciation history is suggested by morphological tendencies especially in male mandibles with assumption from geographical patterns of under sea level.

Hypocreales is one of the largest orders within the class Sordariomycetes in Ascomycota. Several species of this order are cosmopolitan and have a broad range of habitats. Here, we isolated several fungal strains from environmental samples, including freshwater sediment and plant litter. The strains were identified via molecular and phylogenetic analyses of rDNA and other DNA markers, such as TUB, RPB2, and EF1. The morphological characteristics of the fungi were investigated using microscopy, and culture characteristics were assessed from their growth on several media. We identified 17 species previously unrecorded in Korea: Dactylonectria hordeicola, Flavocillium bifurcatum, Fusarium luffae, Ilyonectria ilicicola, Ilyonectria qitaiheensis, Ilyonectria robusta, Lecanicillium aphanocladii, Nectria ulmicola, Neonectria lugdunensis, Ovicillium oosporum, Pseudonectria foliicola, Sarocladium spinificis, Scolecofusarium ciliatum, Trichoderma appalachiense, Trichoderma subviride, Trichoderma taiwanense, and Trichoderma tsugarense.

This study introduces one specimen each of the genera Gymnopilus, Marasmius, and Mycena as an unrecorded species found in the Hwasun Gotjawal and Jeju Gotjawal Provincial Park of the Hangyeong-Andeok terrain, South Korea. Morphological analyses of macroscopic and microscopic features, and molecular analysis of the nuclear ribosomal internal transcribed spacer region were conducted to identify the specimens. Our results indicated that the newly identified specimens were Gymnopilus dilepis, Marasmius tenuissimus, and Mycena seminau. Here, we describe these newly identified mushroom species and provide baseline data on their diversity in Gotjawal, South Korea.

The morphology of the two marine hypotrichous ciliates Apokeronopsis bergeri and A. ovalis, isolated from the Yellow Sea, Korea, are described based on live and protargol-impregnated specimens. It is the first time that these species have been recorded in Korea. In addition, the small subunit ribosomal RNA gene was sequenced for comparison with the public database. The genus Apokeronopsis has recently been established in the family Pseudokeronopsidae, and the two congeners of the Korean population share the following characteristics: one row of one or more buccal cirri; usually two frontoterminal cirri; midventral complex composed of two distinctly separated rows; one left and one right marginal row; number of transverse cirri, more than eight; absence of caudal cirri; two types of cortical granules. Apokeronopsis bergeri differs from A. ovalis primarily in body shape (fusiform vs. oval form), size (usually $260{\times}80{\mu}m$ vs. $160{\times}55{\mu}m$), type II cortical granules (oval vs. round shape; yellow-green vs. mostly colourless and only a few yellow-green in colour), and morphometric data (75-106 vs. 53-70 in adoral membranelles; 37-47 vs. 24-36 in frontal cirri; 9-15 vs. 1-2 in buccal cirri), as well as molecular data (2.87% of pairwise distance).

The Erythropeltidales are a common group of small, mostly epiphytic, marine red algae. However, they are little known in Korea. Many of the described species of Erythropeltidales differ subtly in morphology, and often the morphological differences are due to the substrate or environmental changes. Integration of molecular data with standardized culture conditions has been recommended to account for these algae. A Madagascaria species was first collected from the western coast of Korea and was identified as Madagascaria erythrocladioides based on the morphological and molecular characteristics. Morphological characteristics conformed well with its original description, and the phylogenetic analysis based on rbcL sequence showed Korean M. erythrocladioides nests in the same clade with the original species described in Japan with a genetic distance of 0.0-0.1%. This species was isolated from a red alga, Pterocladiella capillacea, in laboratory culture. The thallus ontogeny and host preference were examined by a co-culture with 13 different species of algae. Results showed a relatively broad host preference in mono-spore attachment and epiphyte development of Madagascaria erythrocladioides. Mono-spores of M. erythrocladioides attached to most of the red algal hosts' surfaces but no crustose thalli developed on some of the algal hosts even after one month of co-culture.
