  • The most recent, Jeong and Nakabo (1997) described Raja koreana as a new species based on an adult female specimen collected from the southwestern coast of Korean Peninsula. Raja koreana has several unique characters not shared with any other supraspecific taxa of Rajoidei, but it was provisionally included in the genus Raja because of having no information of its clasper. Later, two mature males and a few specimens of the species were collected from near the type locality. Therefore, a new genus should be erected for this species. The new genus is characterized by the followings: Rostral shaft straight, narrow and thick in depth: unsegmented base with filamentous cartilage. Dorsal surface of tail with a row of distinct thorns along midline, patches of distinct thorns anterior to first dorsal fin and between first and second dorsal fins in bathe sexes; most thorns directed anteriorly, and thornlets directed posteriorly. Scapulocoracoid comparatively short and high, rear corner high, without anterior bridge, postventral fenestra expanded. Distal tip of accessory terminal 1 claspser cartilage well separated from the tip of accessory terminal 2 clasper cartilage.

  • Structured modeling provides a formal mathematical framework, language, and computer-based environment for conceiving, representing, and manipulating a wide variety of models. It provides a natural framework for integrated modeling owing to its explicit representation power for computational dependencies among submodels. Nevertheless, it doesn't seem to offer a systematic way of composing a structured model from submodels. In order to develop a systematic way, this paper discusses three key issues; (1) Genus structure of validated submodel, (2) Storing method of genus structure, and (3) Integration of genus structures to generate a new genus structure. To visualize the approach, a programming module is developed to implement the step-by-step integration.

  • Objectives : The purpose of this research is to identify the actual origin species imported as Aquilaria malaccensis from Indonesia. Methods : After producing the permanent preparat by cutting off the specimen thinly, we observed its characteristics. Results : The imported ones have not interxylary parenchyma, so none is in the genus aquilaria. Since the aliform parenchyma is mostly observed around the vessel pore, they are in the genus gonystylus, and the rest have no aliform parenchyma, so their specimen is unidentified. Conclusion : The imported as A. malaccensis are not in the genus aquilaria, but most of them are in the genus gonystylus and, for the rest, the specimen is unidentified.

  • In previous studies investigating the genus Xanthoparmelia, thirteen different species have been reported from South Korea alone. However, there currently has been no revisional study performed until now. To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was based on nuclear ribosomal (nr) DNA ITS sequences. A thorough examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) confirmed that eight species of Xanthoparmelia occur inside South Korea. Our analysis further confirmed the colors of the lower surface and medullar chemistry are important taxonomic characters in Xanthoparmelia. This study also presents a detailed description of each species and a key to the genus.

  • In the plant virus world, there are six genera of plant viruses with dsDNA genomes and six genera with ssDNA (Fauquet et al., 2005). The dsDNA viruses are comprised of 4 genera in the Caulimoviridae, the genus Badnavirus and the genus Tungrovirus. The ssDNA viruses are comprised of four genera in Geminiviridae, and the two genera Nanovirus and Babuvirus in the Nanoviridae. The genera Babuvirus and Badnavirus are not well studied in Asia. However, we recognized the significance of two species, Banana bunchy top virus (BBTV) in the genus Babuvirus and Banana streak virus (BSV) in the genus Badnavirus, during the survey of banana viruses in Asia. Their main characters will be introduced in this mini-review.

  • Both the genus Malthacus Kirby and M. angusticollis (Motschulsky) are reported for the first time in Korea. Five North Korean specimens of M. angusticollis were loaned from Hungarian Natural History Museum, Budapest, Hungary and Sungshin Women's University, Seoul, Korea. Here we provide a key to the genus of the Podabrini in Korea and a diagnosis and taxonomic account of the genus Malthacus and M. angusticollis.

  • Two species of mysid, Nipponomysis fusca (Ii, 1936) and N. tenuiculus (Ii, 1940), are newly recorded in Korean fauna. These two species were collected using a light or a bait trap from all coasts of the Korean peninsula. The genus Nipponomysis can be distinguished from allied genus by the following morphological characteristics: third to eighth thoracic endopods with carpopropodus divided into five to six subsegments compared to three subsegments, and anterior four pairs of pleopod in female subequal in length and fifth pair elongated. Nipponomysis fusca is characterized by its acute rostral plate and armature of telson, and N. tenuiculus differs from other species by the number of spine in ventral statocyst region and the shape of the fourth pleopod in male. Herein, we present detailed descriptions of two species from Korean waters with illustrations of morphology. In addition, an identification key to the Korean species of the genus is provided.

  • A new genus Goodingius is proposed to incorporate Hemicyclops adhaerens(Williams), H. arenicolae Gooding, H. elongatus Wilson and H. subadhaerens Gooding, all of which bear the six-segmented female urosome, three mandibular elements (or three elements plus one rudimentary setule), five setae on the first antennular segment, and no inner coxal seta of leg 4. The genus Giardella Canu, a sister taxon of Goodingius, is redefined as possessing eight elements on the third exopodal segment of leg 3, only a single inner seta on the second endopodal segment of leg 4, four spines on the third endopodal segment of leg 4. To the genus Giardella, Hemicyclops caissarum Kihara and Rocha and H. carinifer Humes are assigned, in addition to Giardella ricoensis n. sp., Giardella callianassae Canu, and G. thompsoni A. Scott. Keys to the species of both genera are provided.

  • The family Zopheridae Solier consist of members from several previous families, Zopherinae Solier, Monommatinae Blanchard and Colydiinae Erichson, and more than 1,700 described species are placed in the Zopheridae. They are widely distributed in all major biogeographical regions. The zopheridine genus Bitoma Herbst comprise more than 30 species worldwide including four Palaearctic species. A taxonomic study of the genus Bitoma in Korea is presented. The genus Bitoma and its two species, B. crenata (Fabricius) and B. siccana (Pascoe), are new to the Korean Peninsula. A key, diagnoses, habitus photographs, and illustrations of aedeagus of the Korean Bitoma species are provided.

  • The European corn borer, Ostrinia nubilalis (Hubner) has been known as only one species of genus Ostrinia in Korea. After Mutuura and Munroe(1970) revised the genus Ostrinia, the name of the corn stem borer in Korea has been very confused. The critical examination of the external morphology and the genitalia revealed that species of the genus Ostrinia occurring in Korea are O. fyrbacakus (Guenee, O. scapulalis (Walker), O. zaguliaevi Mut. & Mun. and O. zealis (Guenee)
