  • The taxonomic revision was made on the tribe Harpalini (Coleoptera: Carabidae) in Korea. The Korean species are arranged after Kryzhanovskij et al. (1995) system with minor emendation. This present list is an attempt to bring together the available literature and collection-based information on fauna or taxa recorded from Korea (including some collections from the northern part of the Korean Peninsula, now North Korea). Materials examined for each species, an annotative checklist of Korean Carabidae, and the practical key to tribes and genera are provided. As a result, a total 86 species (and subspecies) belonging to 13 genera are recognized from the Korean Peninsula, of which one species (Harpalus egorovi) is new to South Korea. Distribution of two species, Harpalus tardus and H. tibeticus hsifanicus, are very doubtful in the Korean Peninsula. Besides, numerous new distribution records are given as based on materials deposited in various Universities and private collections.

  • From the soil biodiversity study, we found a species, Phauloppia lucorum (C.L. Koch, 1841) in the family of Oribatulidae (Acari: Oribatida) from the straw mat covering the cherry trees during winter in 2011. This species inhabiting litter and soil of forest, moss and lichens on tree and stones is distributed in the eastern Asia and western and central parts of Europe. In this paper, we illustrate the diagnostic features of a new species with detailed diagrammatic representations and its geographical distribution.

  • Rhizome rot of ginger, caused by Pythium myriotylum, a major limiting factor for its production, has occurred annually, but become severe, especially in hot and humid years with frequent rainfalls in Korea. Most studies on rhizome rot have been carried out since 1980s in the National Institute of Agricultural Sciences and Technology, Honam Crop Experimental Station and Choongnam Provincial Rural Development Administration. Many aspects of rhizome rot, such as survey of the disease incidence, taxonomy, pathogenicity and physiology of pathogen, and ecology of soilborne inocula have been studied in the researches. However, intensive studies have been concentrated on management technologies of the disease including seed-rhizome disinfection, soil sterilization, evaluation of cultivar resistance, and fungicide application, and most developed technologies have been used in commercial farmings. In future, development of resistant varieties and simple soil disinfection technologies applicable in Korean condition and economically feasible fungicide application technology have to be developed for better management.

  • 227 red yeast strains were isolated from air (60 isolates), plant flowers (45 isolates), soil (40 isolates), water (37 isolates) and dairy products (45 isolates). On the basis of 33 different physiological and morphological properties, the isolated strains were assigned to 6 species belonging to 4 genera. Rhodotorula mucilaginosa and Cryptococcus albidus were the most dominant species among red yeasts of the air, plant flowers, water and dairy products, whereas Cryptococcus albidus and Rhodotorula glutinis were prevailed in soil. Cryptococcus laurentii was represented by considerable number of strains, whereas the other spesies were of low occurrence. Noteworthy was the isolation of 2 different groups of isolates belonging to Rhodotorula glutinis. These groups were differentiated from each other on the basis of rhamnose, cellobiose and arabinitol assimilation and growth at $37^{\circ}C$. Systematic position of Rhodotorula glutinis was discussed.

  • This paper gives a brief introduction of taxonmic knowledge of Thomisidae and Philodromidae. The materials and papers quoted here mainly from Dr. Song. I hope that information given in the Korean text will be useful to the study of taxonomy of the Famillies Thomisidae and Philodromidae in Asia.

  • A fungal strain was isolated from a soil sample collected in Korea and designated as YW23-8. Based on a sequence analysis of the internal transcribed spacer (ITS) regions, the isolate was assigned to the genus Sarcopodium. Moreover, a phylogenetic analysis based on the concatenated nucleotide sequences of the ITS regions and the large subunit of the nuclear ribosomal RNA (LSU) gene showed that the strain YW23-8 occupies a distinct phylogenetic position within Sarcopodium. The isolate had significant differences from its closest neighbors, S. circinosetiferum, S. circinatum, S. macalpinei, and S. vanillae. Morphological features such as different conidial structures, the absence of septation in conidia, and the presence of milky white watery droplets along with the results of the phylogenetic analysis clearly distinguish YW23-8 from the closest Sarcopodium species. We therefore conclude that strain YW23-8 represents a novel species of the genus Sarcopodium for which we propose the name Sarcopodium terrigenum.

  • Three fungal isolates designated as CNUFC-YR329-1, CNUFC-PTS103-1, and CNUFC-PTS2-1 were discovered during a survey of fungal diversity of the order Mortierellales from freshwater and pine tree rhizosphere soil samples in Korea. The strains were analyzed morphologically and phylogenetically based on the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA gene sequences. Based on their morphology and phylogeny, the three isolates were identified as Mortierella elongata, M. horticola, and M. humilis, respectively. To the best of our knowledge, M. elongata, M. horticola, and M. humilis, belonging to an undiscovered taxon, have not been previously described in Korea.

  • Talaromyces is a genus within the phylum Ascomycota (class Eurotiomycetes, order Eurotiales, family Trichocomaceae). Many species in this genus are known to produce diverse secondary metabolites with great potential for agricultural, medical, and pharmaceutical applications. During a survey on fungal diversity in the genus Talaromyces in Korea, six strains were isolated from soil, indoor air, and freshwater environments. Based on morphological, physiological, and multi-locus (ITS, BenA, CaM, and RPB2) phylogenetic analyses, we identified five previously unrecorded species in Korea (T. brevis, T. fusiformis, T. muroii, T. ruber, and T. soli) and a new species (T. echinulatus sp. nov.) belonging to section Talaromyces. Herein, detailed descriptions, illustrations, and phylogenetic tree are provided.
