  • Based on our insect collecting trip to the Is. Jin-do, Jeollanam-do Province from June 29 to July 1, 2005, a total of 573 lepidopterous species belonging to 37 families are reported, with adding 122 species new to the locality During our survey, the most dominant species was Cryptolechia malacobyrsa Meyrick (Oecophoridae), followed by Sandrabatis crassiella Ragonot (Pyralidae) and Yponomeuta tokyonellus Matsumura(Yponomeutidae), and the family Noctuidae (165 spp.) was the most diverse taxon in species number. We here also discuss the species representing the climatic feature in the island and compare the species diversity with those of other two major islands in Korea, Is. Geoje-do and Is. Jeju-do. Among the species recognized in this study, two species, Epilepia dentata (Matsumura and Shibata) and Meganola costalis (Staudinger) are recorded in Korea for the first time, in spite of the presence of previous notes on the species which is invalid. The adults and genitalia of the two species are illustrated and described briefly.

  • Rice blast caused by Pyricularia oryzae, which is a major threat to food security worldwide, markedly decreases the yield of rice. Some rhizobacteria called 'plant growth-promoting rhizobacteria' inhibit plant pathogens and improve plant growth by secreting iron-chelating siderophores. The decreased availability of iron adversely affects the survival of pathogens, especially fungal pathogens, in the rhizosphere. This study aimed to determine the morphological diversity of siderophore-producing bacteria, analyze the type of siderophores produced by the bacteria, and examine their growth-inhibitory activity against Pyricularia oryzae. The rhizobacteria were isolated from the rhizosphere of Sembada Hitam variety of black rice plants in Pakem, Sleman, Yogyakarta, Indonesia. In total, 12 distinct isolates were screened for the production of siderophores. It was found that 9 out of 12 bacteria produced siderophore and most of them were Gram positive bacteria. The best siderophore-producing isolates with different type of siderophore were used in further studies. The IS3 and IS14 isolates were found to be the best siderophore producer that produced hydroxamate and mixed type of hydroxamate-carboxylate type of siderophore, respectively. In the dual culture assay, IS14 showed a strong antagonistic effect against Pyricularia oryzae by the 81.17% inhibition.

  • From a result of surveys on the biodiversity monitoring for moths in Korea, six species of micro-moths that were never known from Korea are reported here for the first time from this country. They are: Udea pseudocrocealis(South, 1901) of the family Crambidae, which has been known as endemic to Japan; Epinotia albiguttata (Oku, 1974) of the family Tortricidae, which was known belonging to Hikagehamakia Oku, 1974; and four species of the family Gelechiidae: Protoparachronistis concolor Omelko, 1986 and P. discedens Omelko, 1986, which were described from Primorisk, Russian Far East; Thiotricha pancratiastis Meyrick, 1921, which is known from Isl. Jejudo, and Thiotricha sp. which is being described in a separate paper. Here we provide images of adults and genitalia for the unrecorded species with a brief diagnosis.

  • The genus Philanthus Fabricius, 1790 in Korea are reviewed, and two species, Philanthus triangulum and P. coronata, are treated. The former is new to Korea. This species is easily separated from congeners by dense punctures in propodral enclosure and tri-forked marking in lower face. DNA barcoding test is supportive in our identification as well as conspecitficity of Korean materials showing variation in size and coloration. The observed data on flower associations of this species specified with domestic localites and date are separately provided. The current status of Philanthus coronatus that has been the only representative of the genus but forgotten for a lengthy time in Korea is discussed.

  • A new genus Parkiana Cho, gen. nov., belonging to Torodorinae of Lecithoceridae, is described from Madagascar, with two new species: P. matutinalis Cho & Agassiz, sp. nov. and P. andasibensis Cho & Agassiz, sp. nov. Although superficially similar to Thubdora Park, 2018, some of their morphological characters, such as wing venation, are unique and the species of the genus are grouped apart from Thubdora in a preliminary phylogenetic analysis based on COI barcode sequences. In addition to the specific descriptions, adults and genitalia for the two new species are illustrated.

  • Polygonatum taxa of Korea were classified as two sections, three series and 14 species and 2 varieties and reviewed taxonomically. Among the examined taxa, endemics in Korea were recorded as two species; P. grandicaule Y. S. Kim, B. U. Oh & C. G. Jang and P. infundiflorum Y. S. Kim, B. U. Oh & C. G. Jang. The habitat of Korean unrecorded species, P. acuminatifolium Kom. and P. odoratum var. odoratum were confirmed in this study. Keys to the sections, series and species including description of each taxon were provided here.

In addition, supplementary collecting data are provided for the two species of Erebidae, Lophomilia nekrasovi Kononenko et Behounek and Acontia martjanovi (Tschetverikov), whose Korean distribution has been briefly reported. The female genitalia of Luceria striata are described for the first time. Photos of imagines and genitalia, where available, are provided. All the examined specimens are deposited in the Department of Plant Medicine, Chungbuk National University in Cheongju, Korea.

  • Family Coleophoridae, commonly known as "casebearers", is one of the largest families of Gelechioidea (Lepidoptera), with more than 1,450 described species worldwide, but it has been poorly known in Korea, with only 32 known species of the genus Coleophora Hübner, 1822. Here we present Coleophora fasciella Koo & Baldizzone, sp. nov., a new species to science, and C. mayrella (Hübner, [1813]), an unrecorded species in Korea. Diagnostic characteristics with descriptions of the genitalia are provided with photos of adults, wing venations, and genitalia of both sexes for the species. Mitochondrial cytochrome c oxidase subunit I(COI) barcode sequences for the two species are also provided.

  • Recently, the new genus Parkiana (Lecithoceridae) and its two new species, Parkiana matutinalis and Parkiana andasibensis, were described by the authors from Andasibe, Madagascar. Although the morphological descriptions and figures fully characterized the new genus with two new species in that paper, the journal issue in which the description appeared was published online-only, and the ZooBank LSID, required for validation of new names in electronic-only publications, was not included. Therefore, the present note serves to validate the names of the new genus and species, Parkiana, Parkiana matutinalis and Parkiana andasibensis, by fulfilling Code conditions for nomenclatural availability.

  • The reexamination of the fungal genus Botryosphaeria on 12 plant species of 10 families was carried out based on molecular phylogenetic analyses using the regions of translation elongation factor 1-α, β-tubulin, DNA-directed RNA polymerase II subunit, and internal transcribed spacer region of rDNA and morphological characteristics. Japanese isolates were divided into five clades and include Botryosphaeria dothidea, B. qingyuanensis, B. sinensis, and Botryosphaeria spp. Two species, B. qingyuanensis and B. sinensis have been newly added to the Japanese mycoflora, but their host plants are not specified. Botryosphaeria tenuispora isolated from Leucothoe fontanesiana and insect galls on fruits of Aucuba japonica has been proposed as a new species.
