This study deals with 8 species in 3 families of Collembola including 6 new records of Korea. They are Oudemansia esakii (Kinoshita, 1932), Axelsonia littoralis (Moniez, 1890), Sinella (S. str.) straminea (Folsom, 1899), Sinella (S. str.) coeca (Schott, 1899), Entomobrya marginata (Tullberg, 1871), and Willowsia bimaculata (Borner, 1909). Among them Oudemonsia esakii, Axelsonia littoralis and Entomobrya marginata are halophilous species. Sinella straminea and Sinella coeca were collected from nests of ants comprising the first report of myrmecophilous Collembola from Korea. The Collembolan fauna of Korea is accordingly listed as 203 species in 10 families.

The family Geometridae, which is one of the most species-rich taxa of Lepidoptera, includes more than 23,000 species worldwide and over 800 species in South Korea. Herein, we record six species of Geometridae for the first time in Korea. Jodis urosticta and Jodis amamiensis can be characterized by their greenish wings and strongly dentate ante- and postmedial lines on the fore and hindwings. These species can also be separated by the shape of the valva of the male genitalia. Pelagodes antiguadraria can be characterized by their greenish wings, whitish medial bands on the forewing and whitish postmedial line on the hindwing. Brabira kasaii can be characterized by the thick grayish band-shaped central fascia of their fore- and hindwings. Sauris marginepunctata can be characterized by the greenish ground color of the forewing, the dark ochreous medial bands and subterminal line and the grayish hindwing. Philereme vetulata can be characterized by their dark brownish wing color and the band-shaped central fascia of the forewing, as well as the medially projected postmedial line of the hindwing. Echthrocollix minuta can be characterized by their pale grayish wing color, brownish postmedial and subterminal lines and large discal dot.

We extracted arbuscular mycorrhizal fungal (AMF) spores from rhizospheres of three plants from Upo Wetland, Korea. We identified the isolated AMF spores based on morphological characteristics and phylogenetic analysis of partial 18S rDNA nucleotide sequences. The species diversity of AMF spores was calculated among the study sites and host plants. Consequently, nine species from six genera of AMF spores were identified. We confirmed the species diversity of the AMF spores in rhizospheres affected by host plants in the wetland. In the course of this study, we confirmed a previously unreported AMF species in Korea: Diversispora epigaea. We described the morphological features and molecular characteristics of this previously unreported AMF species.

Aspergillus is one of the largest and diverse genera of fungi with huge economical, biotechnological, and social significance. Taxonomically, Aspergillus is divided into six subgenera comprising 27 sections. In this study, 235 strains of Aspergillus subgenus Circumdati (section: Candidi, Circumdati, Flavi, Flavipedes, Nigri, and Terrei) preserved at the Korean Agricultural Culture Collection (KACC) were analyzed and re-identified using a combined dataset of partial b-tubulin (BenA), Calmodulin (CaM) gene sequences and morphological data. We confirmed nineteen species to be priorly reported in Korea (A. neotritici, A. terreus, A. floccosus, A. allahabadii, A. steynii, A. westerdijkiae, A. ochraceus, A. ostianus, A. sclerotiorum, A. luchuensis, A. tubingensis, A. niger, A. welwitschiae, A. japonicus, A. nomius, A. tamarii, A. parasiticus, A. flavi, and A. oryzae). Among the studied strains, three species (A. subalbidus, A. iizukae, and A. uvarum), previously unreported or not officially documented, were discovered in Korea, to the best of our knowledge. We have given a detailed description of the characteristic features of the three species, which remain uncharted in Korea.

Thirty-six species of the tribe Tortricini (Tortricidae) in Northeast China are listed with available information. Among them, two species, Acleris hastina (Linnaeus) and A. laiordairana (Duponchel), are reported for the first time from China. Croesia crataegi (Kuznetsov) is newly recorded from Northeast China. Available information, including host plant, distributional range, and biological record, are enumerated.

The radulae of six species of bithyniid snails, Bithynia striatula, B. tentaculate, B. siamensis, B. leachi, Gabbia misella and G. australis, were observed by SEM. The radular formula of all the bithyniids studied was 2 : 1 : 1 : 1 : 2. The all teeth were multicuspid and the central teeth had numerous basal denticles. The mesocones of the central and lateral teeth were spade or arrow-head shape. The mesocones of the central teeth and the lateral teeth of B. leachi, G. misella and G. australis were slightly larger than the other cusps in contrast of those of the other species. Number of cusp was varied by the specimen and the species.

Farmed kelp gametophytes were previously observed to be living endophytically in filamentous red algae. The interactions of two farmed kelp species and six red algae were examined in laboratory culture. Undaria pinnatifida (Harvey) Suringar and Laminaria religiosa Miyabe demonstrated the differing abilities of zoospores to become endophytic in four host red algae and neither kelp became endophytic in two non-filamentous red algae. There was a strong seasonal component regarding infectiousness that is associated with the changes in fron erosion in U. pinnatifida from April to June. At the same time, L. religiosa showed no significant changes in frond erosion, and there were no apparent changes in infection levels in the two species they were able infect. This study indicated clear differences between two keip species with regard to their symbiotic relationship to red algae in terms of host specificity and preference of kelp gametophytes.

A revised checklist of the Korean Plecoptera is updated here, with 10 families, 36 genera, and 95 species are reported. Pictetiella asiatica Zwick & Levanidova, Claassenia radiata (Klapálek), Xanthoneuria unimaculata (Zhiltzova) and Sweltsa sp. Ko (temporary name) are known only from the Democratic People's Republic of Korea. Nemoura sahlbergi Morton, Perlomyia kiritshenkoi Zhiltzova, and Neoperla adamantea Murányi & Li are reported for the Republic of Korea in this study. Nemoura ussuriensis Zhiltzova, Capnia sidimiensis Zhiltzova, Eucapnopsis quattuorsegmentata Okamoto, Yoraperla uenoi (Kohno), Isoperla kozlovi Zhiltzova, and Kamimuria lyubaretzi Teslenko are new from the Korean peninsula. Materials, bibliographic data, diagnoses for newly recorded species, and their distributions are provided.

Haloptilus caribbeanensis Park, 1970 (Copepoda, Calanoida, Augaptilidae) is redescribed in detail on the basis of an adult female collected from Suruga Bay, Japan. This is the first record of the species from the Indo-Pacific region. Morphology of the Pacific specimen agrees well with that of the Caribbean Sea and Gulf of Mexico specimens, except for the numbers of mandibular teeth. The former has five teeth and the latter six teeth on mandible. The segmentation and segmental aesthetasc numbers of female antennules of H. caribbeanensis are compared with those of five species of Haloptilus (H. angusticeps, H. fons, H. longicomis, H. ornatus and H. spiniceps). These characters show morphological differentiation at the species level. H. caribbeanensis has no aesthetasc on the proximal segments II, IV, and VI of the female antennules.

Fresh mushrooms were collected during survey field trips to the southern areas of Songnisan National Park for 24 days from April to November in 2002. Through this investigation, a total of 682 fungal collections were obtained and taxonomically amounted to 5 classes, 14 orders, 44 families and 202 species. Among them, six genera Diplomitoporus, Heterochaete, Hydnochaete, Loweporus, Scytinostroma and Tomentellina, and twelve species, Asterostroma cervicolor, Diplomitoporus crustulinus, Fomitopsts cajanderi, Heterochaete delicate, Hydnochaete tabacinoides, Hyphodontia sambuci, Hypoxylon deustum, Lopharia cinerascens, Loweporus roseoalbus, Phanerochaete chrysosporium, Scytinostroma odoratum and Tomentellina fibrosa were confirmed as new to Korea and registered here with descriptions.
