The gromiids (Protozoa ; Sacromastigophora ; Rhizopoda) collected at 9 different sites in Korea , during the period from May to October 1989 were examined, and four species were identified with the scanning electron microscope(SEM). Three species : Euglypha acanthophora. Tracheleuglypha dentata and Trinema enchelys turned out to be new to the Korean fauna.

A taxonomic study of the genus Cafius Curtis in Korea is presented. The world-wide genus Cafius containing 45 species is restricted to seacoasts. Five species are recognized, three of which are reported for the first time in Korea [C. algrum (Sharp), C. mimulus (Sharp), C. rufescens Sharp]. A key, descriptions, and drawings of diagnostic characters of known Korean Cafius species are presented.

Two marine tardigrades belonging to the genus Halechiniscus Richters, H. jejuensis n. sp. and H. remanei Schulz are recorded from Jeju Island, Korea. Halechiniscus jejuensis n. sp. is distinguished from the congeners by the shape and position of lateral body processes, the shape of sensory papilla on leg IV, and the contour of head portion not clearly divided into two lobes. A revised key to the nine species of the genus Halechiniscus is prepared.

This study describes a new record of a thelotremoid lichen (Leucodecton desquamescens) from South Korea. The taxon is characterized by thick, bulging thallus with many calcium oxalate crystal inclusions; an immersed, round to irregular ascomata with free exciple, ellipsoid to $\pm$ roundish submuriform, brown ascospores, and lack of secondary metabolites. A detailed taxonomic description and comments are presented for this taxon. The lichen genus Leucodecton is reported for the first time in South Korea.

A Colletotrichum species was isolated from leaves of Cymbidium exhibiting symptoms of anthracnose. In this study, the isolates obtained were identified based on recent taxonomic approaches for the genus Colletotrichum. The identity of the causal pathogen was confirmed using morphological data and phylogenetic analysis of combined multi-gene dataset (internal transcribed spacer, glyceraldehyde 3-phosphate dehydrogenase, chitin synthase-1, actin, histone3, beta-tubulin, and calmodulin). Pathogenicity testing revealed that the isolates were pathogenic to Cymbidium. Based on these results, the fungal pathogen occurring on Cymbidium orchids was identified as Colletotrichum cymbidiicola, which is a newly recorded species in Korea.

In order to investigate the indigenous prokaryotic species diversity of the Nakdong River system in Korea, fresh water samples from Hapcheonho Lake and Jinyangho Lake were analyzed for bacterial taxonomic diversity. The isolated bacterial strains were identified based on 16S rRNA gene sequences, and those exhibiting at least 98.7% sequence similarity with known bacterial species, but never reported in Korea, were selected as unrecorded species. Eleven unrecorded bacterial species were discovered in this study. The isolates were identified as Aquabacterium citratiphilum, Clostridium ghonii, Curvibacter delicates, Deinococcus depolymerans, Eubacterium moniliforme, Flavobacterium nitrogenifigens, Kineosporia mesophila, Luteibacter jiangsuensis, Microbacterium terricola, Rhizobium larrymoorei, and Sediminicoccus rosea belonging to the phyla Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria and Deinococcus-Thermus. The selected isolates were further characterized for cellular and colonial morphologies, growth conditions, physiological properties, and enzymatic activities. Descriptive information of these previously unrecorded species is also provided.

In order to characterize the current status and distribution of reptiles currently inhabiting the Republic of Korea, the results of survey data were analyzed in this study. The results of this analysis showed that the reptiles were distributed into two orders, seven families, and 21 species, with the exception of six marine reptiles, including Dermochelys coriacea schlegelii, Chelonia mydas japonica, Caretta caretta, Hydrophis melanocephalus, Hydrophis cyanocinctus, and Pelamis platrrus. Also, the taxonomic revisions of several species were suggested, although this would be ill-advised before further studies can be conducted regarding the current status of marine reptiles in the region.

This paper presents a detailed pharmacognostical study of the stem and root of the crude drug Ipomoea quamoclit Linn. (Convolvulaceae). Morphoanatomy of the stem and root have been studied with the aim to aid pharmacognostic and taxonomic species identification using light and confocal microscopy, WHO recommended physico-chemical determinations and authentic phytochemical procedures. The physico-chemical, morphological and histological parameters presented in this paper may be proposed as parameters to establish the authenticity of stem and root of I. quamoclit and may possibly help to differentiate the drug from its other species.

In Korean Peninsula including neighboring islands and Japanese Islands identical firefly species or the species belonging to same genera occur together in both territories. These geographic firefly species, nonetheless, have never been subject to taxonomic consideration together until recently, lacking clear species status and phylogenetic relationships. A recent serial study of these fireflies using luciferase gene and/or portions of mitochondrial DNA sequences provided some insight into these populations in terms of validity of species name, phylogenetic relationships, and speciation event. In this article, thus, we have reviewed the recent progress on phylogenetic and/or population genetic aspects of these species, i.e., Hotaria-group fireflies, Luciola lateralis, and Pyrocoelia rufa to better understand the firefly species in these regions.

A taxonomic study on the freshwater harpacticoids of the genus Canthocamptus has been accomplished as one of the serial researches on the family Canthocarnptidae in South Korea. As a result of it, a total of seven species of the genus are listed, two of which are new to Korean fauna: C. kitaurensis Kikuchi and C. macrosetifer Ishida. Additional materials of five species belonging to Canthocamptus mirabilis species group are recorded. A key to the seven species of the genus Canthocamptus known from Korea is prepared.
