Ahyoung Choi,Jin-Woo Bae,CHANG-JUN CHA,Jongsik Chun,임완택,Kwang-Yeop Jahng,Che Ok Jeon,KISEONG JOH,김승범,성치남,Jung-Hoon Yoon,조장천 국립생물자원관 2015 Journal of species research Vol.4 No.2

As a subset study to discover indigenous prokaryotic species in Korea, a total of 39 bacterial strains assigned to the classes Betaproteobacteria and Gammaproteobacteria were isolated from diverse environmental samples collected from soil, tidal flat, freshwater, seawater, seaweed, wetland, plant roots, guts of insects, and fermented foods. From the high 16S rRNA gene sequence similarity (>99.1%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 39 species have been described in Korea; therefore 4 species of 4 genera in the order Burkholderiales and 1 species in the order Neisseriales within the class Betaproteobacteria, and 10 species of 6 genera in the order Alteromonadales, 11 species of 3 genera in the order Pseudomonadales, 4 species of 4 genera in the order Enterobacteriales, 2 species of 2 genera in the order Vibrionales, 1 species in the order Aeromonadales, 3 species of 3 genera in the order Oceanospirillales, 2 species of 2 genera in the order Xanthomonadales, and 1 species in the order Chromatiales within the Gammaproteobacteia are reported for proteobacterial species found in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.

최지은,인경호,김봉석,김경희,김진석,김용인,이병윤,임채은 국립생물자원관 2020 Journal of species research Vol.9 No.1

Chrysosplenium grayanum Maxim. (Series Nepalensia), which had been known to be restricted to Japan, was newly discovered from Mt. Cheongtae in Yeonggwang-gun, Jeollanam-do, located in the southern part of the Korean Peninsula. Species identification was confirmed using morphological characteristics and DNA sequence data, while comparing with materials obtained from Japan and herbarium specimens. Chrysosplenium grayanum is clearly distinguished from the remaining taxa of the genus Chrysosplenium by having glabrous plant body, opposite leaves, cylindrical papillae with roundish head at the tip on the smooth seed surface, and four stamens. Molecular sequence data of the nuclear ribosomal ITS regions, chloroplast rbcL and matK genes strongly supported that this previously unknown Chrysosplenium species from Korea is C. grayanum. Taking the molecular and the morphological evidence into consideration, it is clear that newly discovered Chrysosplenium population in Korea is conspecific with the widely distributed C. grayanum in Japan. In this paper, we provide a description, illustration, and photo images of Chrysosplenium grayanum from Korea and also a key to the Chrysosplenium species in Korea.

Nannophya koreana sp. nov. (Odonata: Libellulidae): A new dragonfly species previously recognized in Korea as the endangered pygmy dragonfly Nannophya pygmaea Rambur

배연재,Jin Hwa Yum,김동건,서경인,강지현 국립생물자원관 2020 Journal of species research Vol.9 No.1

A new dragonfly species, Nannophya koreana sp. nov., is described from Korea on the basis of morphology and mitochondrial cytochrome oxidase c subunit I (COI) gene sequences. Nannophya materials from Korea and other areas in Southeast Asia were compared. The new species was previously recognized in Korea as the endangered pygmy dragonfly Nannophya pygmaea Rambur, 1842, which is widely distributed in insular and peninsular Southeast Asia. However, male adults of the Nannophya population in Korea could be distinguished from other N. pygmaea populations by the presence of a thick, incomplete black stripe on the lateral synthorax that terminated at half-length (vs. continuous to wing base), light orange (vs. red) anal appendages, and 4-5 (vs. 2-3) black teeth on the ventral superior appendages. In addition, the body length of N. koreana was generally larger (1.2-1.4 times) than that of N. pygmaea, regardless of life stage. COI gene sequences from the two groups exhibited substantial genetic differences (>12%), thereby sufficiently substantiating their differentiation. The taxonomic status, distribution, and habitat of the new species are discussed.

New records of coccoid green algae in Korea

김용재 국립생물자원관 2017 Journal of species research Vol.6 No.1

Coccoid green algae collected from March to November 2015 from 79 freshwater ecosystem sites throughout South Korea, including lakes, ponds, swamps, streams, and rivers, were identified using light microscopy. A total of 218 taxa were identified, among which 11 were new species records in Korea; these 11 species were found at four sites (Hanagang River, Chukdong reservoir, Chukdong fishery, and Deokjin reservoir). The new species recorded were Fotterella tetrachlorelloides, Trochiscia naumannii, Keriochlamys styriaca, Placosphaera opaca, Siderocystopsis fusca, Siderocelis oblonga, Siderocelis estheriana, Pachycladella umbrina, Pachycladella zatoriensis, Crucigenia mucronata and Scenedesmus sempervirens.

Sergey Mikhailovich Muzyka,Olga Valentynovna Bondarenko,Elena Aleksandrovna Makarova 국립생물자원관 2015 Journal of species research Vol.4 No.2

The correlation coefficient (r) between the meteorological parameters and the gross biological productivity of the most common mycorrhizal mushrooms was determined. The results can be both of theoretical and practical importance.

A new species of Cavernocypris (Ostracoda) from Texas (U.S.A.) with a taxonomic key

Okan Külköylüoğlu 국립생물자원관 2020 Journal of species research Vol.9 No.2

Cavernocypris reddelli n. sp. is a new species of the genus Cavernocypris collected from spring waters of Texas, U.S.A.. This is the sixth species of the genus described so far. It can be distinguished from the other species of the genus by the shape and length of carapace, presence of robust marginal pore canals on right valve, number and length of setae on second antenna, shape of hemipenis, numbers of whorls on the Zenker organ, and differences in other parts of chaetotaxy. The new species was compared with other species and a new taxonomic key for the genus is presented for future studies.

A new record of the subgenus Eusimulium Roubaud from Korea with an updated key to genera and subgenera of Korean black flies (Diptera: Simuliidae)

김삼규 국립생물자원관 2020 Journal of species research Vol.9 No.2

Larvae and pupae of Simulium (Eusimulium) satsumense were collected and recorded from Korea for the first time. Detailed descriptions and photographs of both immatures are provided. Currently, 42 species are known from the subgenus Eusimulium, which is found globally, mainly in the Holarctic Region, but unknown from Korea. Members of the subgenus Eusimulium are morphologically homogeneous in male, female, and pupa, making them extremely difficult to distinguish from one another. S. (E.) satsumense can be distinguished from other Korean black flies by the following combination of the characteristics: Pupa: Gill of four slender filaments, dorsalmost filament strongly divergent from other filaments; cocoon slipper shaped without anterodorsal projection; Larva: Head spots distinctly positive; postgenal cleft short, apically rounded or squared; antenna with proximal segment brown; abdominal segments IX with prominent ventral tubercles; and rectal papillae of three simple lobes. In addition to descriptions for larvae and pupae of the species, a key to genera and subgenera of Simulium of Korean black flies are also provided.

Yury Evgenjevich Vashukevich,Elena Valirievna Vashukevich,Gottlieb Polzer,Liza Polzer,Svetlana Viktorovna Shvetsova,Victoria Mikhailovna Khantakova 국립생물자원관 2015 Journal of species research Vol.4 No.1

The article is devoted to the study of the density dependence of the horns tissue on the species and the age of the representatives of the deer family. In scientific literature this problem was covered partially. Basic physical parameters (mass, volume, and density) of horns from red deer (Cervus elaphus), fallow deer (Dama dama), European (Capreolus capreolus) and Siberian roe deer (Capreolus pygargus) were estimated. The present study was designed to analyze the results for making identification of species and age of the animal possible.
