한국산 박새속 조류 Porus maior(박새), Parus ater(진박새), Parus palustris(쇠박새), Parus varius(곤줄박이)의 핵형을 C-banding 방법으로 분석한 결과 ZZ-ZW 염색체를 동정, 확인할 수 있었으며, 구조적 이질염색질의 부위가 일반염색 방법에 의한 핵형 비교에서 보다 종간에 더 많은 차이를 나타냈다. 그러나 일반염색 방법과 C-banding 방법 만으로는 4종간의 종분화 기작을 추측할 수 없었다. The chromosomal analysis of Paws motor, Paws ater, Pahs palustris and Pows varius of the genus Paws in Korea were performed by C-handing method. The identification of sex chromosones was ascertained and the part of constitutive heterochromatin was more different between interspecies than by conventional Giemsa staining method. However, conventional Giemsa staining and C-banding methods could not explain mechanisms of speciation between four species.

Taxonomic confusion has been presented within freshwater crayfishes of the genus Cambaroides since Starobogatov published morphological definition and revision of the group in 1995. He suggested that Cambaroides should be revised: the C. dauricus, contained three species C. dauricus, C. wladiwostokiensis, and C. koshewnikowi; the C. schrenckii with two. species C. schrenckii and C. sachalinensis. Also Straovogatov did not take into account the previous data. of crayfish distributions. In order to. clear up the confusion, the taxonomy of crayfish sampled from Mongolia, Russia, China, and North Korea was reassessed. Starovogatov's key could not lead to the correct identification. Also, detailed observations of apical robe of the male first pleopod did not support the taxonomy on the genus Cambaroides proposed by Starobogatov in 1995. However, some local variations of morphology exist in rostrum, pleuron, and telson of Asian crayfish. Future studies should be concentrated on whether there are geographical clines of morphology or if taxonomic subdivision is necessary.

To find microorganisms producing esterase inhibitors, microbes were isolated from soil samples that were collected at different locations in Korea and screened for inhibitory activities. One of the inhibitor-producing strains was named strain DMC-498. This strain was found to be a new species of the genus Streptomyces by comparison with the characteristics of morphology and metabolisms of the other species of the genus.

The planthopper subfamily Achilinae (Metcalf, 1938) from Korea is taxonomically revised. Six genera and seven species are recorded among Korean fauna. Among them, one genus, Phenelia Kirkaldy, and two species, Phenelia striatella (Matsumura, 1914) and Deferunda qiana Chen and He (2010) are new to Korea. The male genital structures of all these species are described and illustrated, plus an identification key to the tribe, genus, and species is provided.

The genus Luidia belongs to the family Luidiidae in the order Paxillosida. It is a common littoral taxon, and the depth range of the Korean fauna is generally 0-100 m. However, specimens of Luidia were collected from Jeju Island in Korea at 150-160 m depth and identified as Luidia sagamina sagamina $D{\ddot{o}}derlein$, 1920. This species is determined by morphological characteristics and mitochondrial cytochrome c oxidase subunit I sequence analysis. Luidia sagamina sagamina is a very rare sea star in worldwide and it only collected previously from Sagami Bay, Japan, and is newly reported in Korea. Four species of Luidia, including L. s. sagamina, are recorded in the Korean fauna.

A fungus of the genus Kordyana, found on leaves of Commelina communis and C. minor exhibiting white smut-like symptoms, was identified as Kordyana commelinae based on morphological characteristics and two rDNA sequence analyses. We report the novel occurrence of the genus Kordyana in Korea and the association of K. commelinae with the host plant species. As well, we provide the necessary mycological information to resolve species delimitation and taxonomic problems of Kordyana.

Previously, we found the operon random primer (OP-5A) that is characteristic the genus Panax by randomly amplified polymorphic DNA (RAPD) analysis. However, OP-5A primer is limited to apply on the differentiation of only crude herbal plants. To construct more sensitive and unique primers on the genus Panax, ginseng-specific DNA profile (350 bp) that was amplified by OP-5A primer were inserted in a plasmid vector in the TA cloning method and sequenced. We designed the PCR primers (Forward: 5＂-AGGGGTCTTGCTAT AGCGGAAC-3＂, Reverse: 5＂-AGTCTTAATTTCATATTTTCGTATG-3＂) and identified the unique ginseng band (350 bp) in commercial granule products including ginseng extracts as well as crude ginseng plants by nascent PCR.(omitted)

The genus Phaedrotoma Foerster, 1862 (Hymenoptera: Braconidae: Opiinae) parasitize in larvae of flies, Tephritidae, Agromyzidae, Ephydridae, Anthomyiidae, Scathophagidae, and Drosophilidae, of which 12 species are recorded in South Korea. As results of our survey, Phaedrotoma rugulifera Li et al. (2013) and Phaedrotoma vermiculifera Li et al. (2013) are reported for the first time in South Korea. Those specimens were collected by sweeping. Descriptions, and diagnostic illustrations of P. rugulifera and P. vermiculifera are provided.

The aim of this study was to characterize a new fungal species, Acremonium conglutinatum, isolated from air samples collected in Wando, South Korea. Phylogenetic analysis based on the internal transcribed spacer and large subunit regions revealed its unique position within the genus Acremonium. The isolated strain displayed distinct morphological characteristics, including ellipsoid or bent-ellipsoid conidia formed in clusters on the phialides. These features differentiate the new species from closely related species within the genus. This study describes the morphological and molecular characteristics of A. conglutinatum and emphasizes its phylogenetic relationships with other Acremonium spp. The identification of this novel species contributes to our understanding of the diversity and ecological role of Acremonium.
