  • A comparative study of the petiole anatomy in the tribes Forsythieae (Abeliophyllum, Forsythia) and Fontanesieae (Fontanesia), including one related genus Myxopyrum belonging to Myxopyreae, was carried out using light microscopy. The anatomical characteristics of the distal, medial and proximal parts of the petiole were studied to document any differences. We are described in detail based on their quantitative and qualitative characteristics. Three crystal types (acicular, druse, and prismatic crystals) were found in both Fontanesia and Myxopyrum within all of the studied taxa. Uni-cellular non-glandular trichomes were found in Abeliophyllum and three Forsythia taxa (F. europaea, F. giraldiana, and F. japonica). All features were compared and the vascular patterns of the petiole were distinguished in two types: Type 1A: Trace continuous arc - without crystals (Abeliophyllum, Forsythia), 1B: with crystals (Myxopyrum), Type 2: Trace invaginating at ends with crystals (Fontanesia). A detailed anatomical description of the studied taxa is provided, and its systematic importance is also briefly discussed. In conclusion, some petiole anatomical characteristics (e.g., the main vascular patterns, the presence/absence of crystals) can be useful for diagnostic features as well as partly for supporting the recently proposed molecular phylogeny.

  • Three harpacticoid species of the genus Onychocamptus are reported from the inland waters of South Korea: O. vitiospinulosa (Shen and Tai), O. mohammed (Blanchard and Richard) and O. bengalensis (Sewell). Of these, O. vitiospinulosa and O. mohammed are newly added to Korean copepod fauna. Onychocamptus vitiospinulosa is redescribed. Systematic accounts on the morphological details and the intraspecific variabilities are provided with a key to the Onychocamptus species from Korea.

  • The nutlet morphology and pericarp structure of 14 taxa (4 taxa of the genus Glechoma and related taxa) were studied by light and scanning electron microscopy, and a detailed description of nutlet morphological features for all examined taxa is provided. The shape of the nutlet is ovate to elliptic. Its size is 1.36-3.83 mm in length and 0.80-2.65 mm in width. The largest one was found in Marmoritis rotundifolia, while the smallest one was in Agastache nepetoides. Three different surface types were recognized in the studied taxa based on differences in cell outline and cell boundary relief (rectangular, pitted, and ridged negative reticulate-cell). Three types of trichome (uni-cellular non-glandular trichome, multi-cellular non-glandular trichome, and peltate glandular trichome) were distributed in the nutlets. The pericarp is formed in three layers (i.e., exocarp, mesocarp, and endocarp including sclenchyma tissue), and the pericarp in the studied species is $39.0-237.5{\mu}m$ thick. The morphological and anatomical features (the nutlet shape, surface type, and trichome distribution) in the genus Glechoma and related taxa are described and discussed.

  • Morphological and anatomical characters of selected 3 taxa of Rhynchospora were reexamined. The epidermal patterns of achene and leaf were investigated using a scanning electron microscope (SEM) and a light microscope (LM). Morphological characters such as length and width of bract, spikelet, scale, achene, stem, leaf and leaf sheath, and shape of inflorescence, spikelet, scale, apex of scale, perigynium and achene, and number of stigma and anatomical characters (transectional shape of the stem, and leaf: vascular bundles in stem and leaf epidermal patterns: shape of fundamental epidermal cell and cell wall, type of silica body, subsidiary cell shape, size and frequency of stomatal complex of leaf) were useful for the identification. Keys based on data were presented here.

  • This study carried out to certify of taxonomic delimitation in A. artemisiaefolia, A. trifida, A. trifida for. integrifolia, and A. psilostachya in the area of literature and experiment. A. psilostachya was not a vestige of naturalized in Korea and A. trifida and A. trifida for. integrifolia didn't have any valuable differences of morphological and molecular biological experiment. I arranged that naturalized species in Ambrosia are A. artemisiaefolia L. and A. trifida L. in Korea.

  • Anatomical features of seed coat were examined on Trollius, Calathodes, and Caltha of Ranunculaceae to evaluate the taxonomic circumscription of Megaleranthis saniculifolia, which is monotypic and endemic in Korea. Megaleranthis saniculifolia showed the exotestal type of seed coat exhibiting a well-developed palisade structure in exotesta and its external surface of exotesta cells was concave. On the other hand, the shape of exotesta cells in Caltha was cuboidal and the outer surface was smooth. The exotesta of Calathodes seeds was formed of the palisade structure like M. saniculifolia, but the outer surface of exotesta cells was smooth. The palisade structure was much better developed in the exotesta of Calathodes as well as Megaleranthis seeds than in the exotesta of Trollius seeds. The outer surface of exotesta cells in Trollius was either convex or concave according to the species examined. Since the genera of the subtribe Calthinae of the family display differences in seed sculpturing and the anaotmy of seed coat, these characteristics are useful to access taxonomic relationships among them. The morphological and anatomical features of seed coat suggest that Megaleranthis be possibly allied with Trollius rather than Caltha or Calathodes. Concave surface of seed coat cells and well-developed palisade structure of exotesta are shared by M. saniculifolia and some species of Trollius in common.

  • Specimens of spider mites parasiting on conifer trees were collected from Korea during the period from May, 1986 to June, 1988. As a result, seven species belonging to the tribe Tetranychini, subfamily Tetranychinae, family Tetranychidae were identified as follows: 1. Panonychus citri(McGregor, 1916), *2. Oligonychus clavatus(Ehara,1959), *. O.hondoensis(Ehara,1954), *4. O.pustulosus Ehara, 1962, 5. O.karamatus(Ehara, 1956), 6. O.perditus Pritchard and Baker, 1955, 7. O. ununguis(Jacobi, 1905). Of which, three species with asterisk are newly recorded from Korea.

  • A taxonomic review of the genus Leiognathus was made based on specimens collected from the coast of Korea from 1997 to 2004. The genus Leiognathus in Korea includes 6 species: Leiognathus elongatus, L. fasciatus, L. lineolatus, L. nuchalis, L. rivulatus, and L. bindus. Leiognathus bindus is reported for the first time in Korea. It is characterized by having bright orange spots between the 2nd and 5th spines of the dorsal fin. Detailed morphological measurements and counts and a key to species of Leiognathus from Korea are provided.

  • Fourteen species of the genus Gonocephalum and one species of the genus Opatrum (Tenebrionidae, Opatrini) from Korea have been previously recorded. They are taxonomically reviewed based on many faunistic reports and research papers. We also examined many specimens including voucher materials of the previous studies. Among the recorded species, G. sabulosum is excluded because it was misidentified for the individual variation of Opatrum subaratum. We couldn’t find any Korean materials of four species (G. japanum, G. bilinearum, G. outreyi, G. malayanum), and used the materials determined from other countries. Key to 13 species of the genus Gonocephalum, illustrations of adults and male aedeagus are provided.
