Pyrgotidae is a small acalyptrate family including about 370 species worldwide and little attention has been given to their systematics until recently. Latest changes in taxonomic status of some of the Korean species made this review inevitable. In the present study, the Korean pyrgotid species are reviewed with discussion of their taxonomic status. We also provide a revised key to all 14 Korean species (seven Adapsilia, three Eupyrgota, two Parageloemyia, one Porpomastix, and one Tephritopyrgota species) supplemented by digital images to facilitate accurate identification.

South Korea presently harbors less than 800 long-tailed gorals (Naemorhedus caudatus), an endangered species. I report for the first time on the taxonomic status and genetic diversity of the Korean species using non-invasive fecal sampling based on mitochondrial cytochrome b gene sequence analyses. To determine the taxonomic status of this species, I reconstructed a consensus neighbor-joining tree and generated a minimum spanning network combining haplotype sequences obtained from feces with a new goral-specific primer set developed using known sequences of the Korean goral and related species (e.g., Russian goral, Chinese goral, Himalayan goral, Japanese serow, etc.). I also examined the genetic diversity of this species. The Korean goral showed only three different haplotypes. The phylogenetic tree and parsimony haplotype network revealed a single cluster of Korean and Russian gorals, separate from related species. Generally, the Korean goral has a relatively low genetic diversity compared with that of other ungulate species (e.g., moose and red deer). I preliminarily showcased the application of non-invasive fecal sampling to the study of genetic characteristics, including the taxonomic status and genetic diversity of gorals, based on mitochondrial DNA. More phylogenetic studies are necessary to ensure the conservation of goral populations throughout South Korea.

Pagurus is the most diverse hermit crab genus in Korea. In this study, the cytochrome c oxidase subunit I (COI) and 16S rRNA of 24 individuals from four Korean Pagurus species (i.e., 7 Pagurus brachiomastus, 8 P. proximus, 8 P. simulans, and 1 P. rectidactylus) were sequenced and analyzed. No genetic difference was found between the COI and 16S rRNA sequences of P. brachiomastus and P. simulans, and the COI sequences of P. rectidactylus and P. quinquelineatus (comparative species from NCBI). Considering the morphological and ecological characteristics together, we assume that P. simulans and P. rectidactylus are subspecies of P. brachiomastus and P. quinquelineatus, respectively. This study should facilitate further research on the taxonomic status of these species.

분리(分離)된 저영양세균(低營養細菌)중, 질소고정균(窒素固定菌)과 메타놀 이용균(利用菌)의 대부분이 분류학상(分類學上)새로운 균(菌)으로서 특정지을 수 있었다. 분리된 질소고정균의 경우 형태적 생리적인면에서 Azospirillum에 대응하는 균이라 생각되어 졌으나, 균체지방산조성 및 키논종(種)에 있어서 명확한 차이점을 보여 Azospirillum 속의 새로운 균주로써 추정되었다. 메타놀이용균중 부속기갖는 세포로된 균주들은 prosthecate bacteria(Hyponycrobium sp.)에 대응하는 균이라고 추정되어졌다. 그이외의 regular irregular rods를 나타내는 메타놀이용균에 대해서는 균체지방산조성면에 있어서 서로 다르다는 것이 주목되어져 균체지방산조서의 분석결과(分析結果)를 갖고 화학분류(化學分類)의 측면에서 재검토한 결과 유사도(類似度) 85-90% level에서 8개 cluster로 나뉘어졌다. 일부, cluster에 속하는 균주는 Pseudomonas sp.와 유사한 균으로 추정되었으며, 그 외의 균주들에 대해서는 분류학적 검토가 더욱더 필요로 한다.

Elsholtzia hallasanensis, E. springia, and E. splendens var. fasciflora (Lamiaceae) were reported recently as new species or new varieties of E. splendens according to their morphological characteristics. To reappraise the taxonomic status of these additional taxa and to determine the relationships between all Korean Elsholtzia taxa except E. saxatilis, which is distributed in North Korea, molecular studies based on the nrDNA (ITS) and cpDNA (rpl16, and trnH-psbA) sequences of seven taxa of Elsholtzia and one outgroup were carried out. The molecular data support that E. angustifolia and E. minima are distinct species from E. splendens and E. ciliata, respectively, because they have several private marker genes and show monophyly. The molecular data also support that E. splendens has a very close taxonomic relationship with both E. hallasanensis and E. springia. We found that E. splendens var. fasciflora, with multiple inflorescence, was based on several private marker genes and on the monophyly of its trees, suggesting that it can be considered as a variety. Elsholtzia springia, with the same sequences and the same morphological characteristics with E. hallasanensis after transplanting, should be treated as a synonym of E. hallasanensis. Moreover, we consider the taxonomic status of E. hallasanensis as E. splendens var. hallasanensis (Y. Lee) N.S. Lee & C.S. Lee, stat. nov.

The hairtail (currently recognized as Trichiurus lepturus in Korea) is one of the most important commercial fish species in Korea, Japan, China, and Taiwan. Because the amount of catches has been steadily declining, we must determine the early life stages of the hairtail from the viewpoint of resource management. Furthermore, the taxonomic status of the hairtail is unclear among ichthyologists, potentially creating management difficulties. Therefore, the purpose of this study was to compare morphological and molecular information on eggs, larvae, and adults of hairtail from Korea with that of T. lepturus from the Atlantic Ocean, and to review the taxonomic status of the hairtail. A total of 510 base pairs of the mitochondrial DNA cytochrome oxidase subunit I sequences of 12 eggs, 2 larvae, and 11 adults of the hairtail from the Korean waters clearly matched those of Trichiurus japonicus adults (d = 0.000-0.014) from the East China Sea rather than those of T. lepturus (d = 0.100-0.110) from the Atlantic Ocean. Our results also showed that larvae of the Korean hairtail are different than those in the Atlantic Ocean in having no melanophores along the ventral edge of the lower jaw. Therefore, our findings suggest that the hairtail in the Korean waters may not be T. lepturus, but T. japonicus.

Following the taxonomic reassignment of Schizopora and some Hyphodontia species into Xylodon, we confirmed nine Korean species of Xylodon in a previous study. In the present study, we propose Korean names for these Xylodon species according to the Principles of the Mycological Terminology Review Committee of The Korean Society of Mycology.

The water deer, Hydropotes inermis (Cervidae), is native to China and Korea and has two subspecies of the Chinese water deer (Hydropotes inermis inermis) and Korean water deer (Hydropotes inermis argyropus). To date, only the Korean water deer has been reported in South Korea. In this study, however, an intraspecific phylogeny and haplotype analysis based on mitochondrial cytochrome oxidase I indicated that both Korean and Chinese water deer are found in South Korea. The populations of the two Korean genetic lineages did not show distinct geographic distributions. Further morphological studies on the Korean water deer will be required to confirm its taxonomic status.

We investigated the taxonomic status of the Korean populations of Eurema hecabe (Linnaeus, 1758) based on morphology and nuclear triose phosphate isomerase (Tpi). Up to now, the Korean population of E. hecabe was classified into E. mandarina (de l'Orza, 1869) based on morphological characteristics. A previous study raised the possibility of the Jeju-do population to be E. hecabe based on the color of forewing's fringe. However, morphological examination showed that the Korean population found in southern areas (Gyeonsang and Jeolla provinces), including Jeju-do is E. mandarina. In particular, the external morphology of autumn seasonal type of the Korean population was almost same as the Japanese mainland population, which is known as E. mandarina. Furthermore, sequence analysis of Tpi gene from nine individuals of E. mandarina collected in South Korean localities including Jeju-do clearly showed that all Korean specimens truly belong to E. mandarina.
