  • A taxonomic review of the Korean Lycocerus (Cantharidae, Coleoptera) was presented. Through this study, total of four species were found from Korea including a species new to Korea, Lycocerus striatus. We newly provided a key to the Korean Lycocerus species and the distributional map on each species in this study.

  • The genus Rhogadopsis Brethes, 1913 (Hymenoptera: Braconidae: Opiinae), which mostly parasitizes mining flies (Diptera: Agromyzidae), has been considered to subgenus in the genus Opius Wesmael, 1835. However, according to having the derived wing venation and forming a monophyletic clade, the genus Rhogadopsis is elevated to generic rank. As results of faunal survey in Yeoseo-do, Jeonnam, South Korea, the male specimen of Rhogadosis obliqua were collected by sweeping. Diagnosis, description, distribution and diagnostic illustration of Rhogadopsis obliqua are provided.

  • 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 traditional animal phylogenetic tree is to align the body structure of the animal phylums from simple to complex based on the initial development character. Currently, molecular systematics research based on the molecular, it is on the fly, is again estimating prior trend and show the new genealogy and interest of the evolution. In this paper, we generate the training set which is obtained from a DNA sequence ans apply to the classification. We made use of the mitochondrial DNA for the experiment, and then proved the accuracy using the MEGA program which is anaysis program, it is used in the biology field. Although the result of the mining has to proved through biological experiment, it can provede the methodology for the efficient classify and can reduce the time and effort to the experiment.

  • The genus Areotetes van Achterberg & Li, 2013 (Hymenoptera: Braconidae: Opiinae), which is endoparasitoid of mining or infesting of fruit dipterous larvae, have been reported for the first time in China. Currently, four species of the genus Areotetes have been known from the province Hunan and Fujian, China. In this study the genus Areotetes with Areotetes carinuliferus van Achterberg & Li, 2013 is reported for the first time from Korea. Material studied in the present study were collected by sweeping in Mt Gongchi, Eochungdo, Province Jeonbuk, Korea. Herein, diagnosis of genus, description, distribution, and diagnostic illustration of A. carinuliferus are provided. In addition, DNA barcode data of the partial gene of mitochondrial cytochorome c oxidase subunit I (COI) are included.

  • A unicellular green alga was axenically isolated from the Port of Jeongja, Ulsan, Korea. Morphological, molecular, and biochemical analyses revealed that the isolate belonged to Heterochlorella luteoviridis. This is the first report of this species in Korea. The microalgal strain was named as H. luteoviridis MM0014 and its growth, lipid composition, and biomass properties were investigated. The strain thrived over a wide range of temperatures ($5-30^{\circ}C$) and withstood up to 0.5 M NaCl. The results of gas chromatography/mass spectrometry analysis showed that the isolate was rich in nutritionally important polyunsaturated fatty acids. Its major fatty acids were linoleic acid (35.6%) and ${\alpha}$-linolenic acid (16.2%). Thus, this indigenous marine microalga is a potential alternative source of ${\omega}3$ and ${\omega}6$ polyunsaturated fatty acids, which are currently obtained from fish and plant oils. Ultimate analysis indicated that the gross calorific value was $19.7MJ\;kg^{-1}$. In addition, the biomass may serve as an excellent animal feed because of its high protein content (51.5%). Therefore, H. luteoviridis MM0014 shows promise for applications in the production of microalgae-based biochemicals and biomass feedstock.
