본 연구에서는 국내에서 처음 발견된 Aulacophoroides hoffmanni (Takahashi, 1937)를 최초로 보고한다. 2024년 야외조사에서 한국의 서부 2개 지역의 등나무(Wisteria floribunda (Willdenow))에서 심각한 피해를 주고 있는 A. hoffmanni를 확인하였다. 무시성충의 상세한 형태 기재와 계측값을 제시하였으며, 생체 및 슬라이드 표본 사진을 포함하였다. 이 종은 등나무에 심각한 피해를 주고 있어 관상용 등나무의 주요 해충이 될 것으로 예상된다.
The Pieris napi-complex in East Asia that comprises P. melete Ménétriés, 1857, P. dulcinea (Butler 1882), and P. nesis (Fruhstorfer 1909) has been taxonomically challenging to distinguish due to their similar appearances. In this study, P. nesis, typically found in central Japan, was discovered in the highlands on Jejudo Island, the southernmost part of the Korean Peninsula. We conducted a molecular phylogenetic analysis using mitochondrial COI gene to explore the relationship between P. dulcinea and P. nesis, and confirmed that P. nesis occurs in Korea. This paper provides the morphological characteristics of P. nesis compared to P. dulcinea, along with DNA data.

The genus Xylaria, a large and diverse group within Ascomycota, plays an important role in forest ecology as decomposers. Several new Xylaria species have been recently identified. In this study, the morphological and molecular characteristics of Xylaria species found in Korea were analyzed based on the latest classification systems. Notably, species with characteristics similar to Xylaria cubensis and X. rogersii, which were not previously reported in Korea, were identified. X. cubensis grows on rotten wood and is characterized by brownish clavate stromata with rounded apices and small, dark ascospores. X. rogersii, found in Magnolia spp., has long stromata with a dark-brown, fine-striped outermost layer and subhyaline to yellowish single-celled ascospores. Genetic analysis using a combined dataset of internal transcribed spacer, β-tubulin, and RPB2 sequences revealed that these species form a distinct group separate from other known species. Further investigations included detailed macro- and micromorphological studies, as well as molecular analyses to establish their taxonomic positions more precisely.
A specimens of Hippichthys spicifer (Rüppell, 1838) (92.7 mm in standard length) were collected from Jeju Island, Korea on July 19, 2023. The species is well distinguished from Hippichthys heptagonus by the number of trunk rings between the anus and dorsal fin (two in H. spicifer vs one) and the presence of black stripes on the abdomen (present in H. spicifer vs absent). It is also distinguished from Hippichthys penicillus by the direction of the lateral median trunk ridge (deflected in H. spicifer vs. straight). Mitochondrial DNA cytochrome c oxidase subunit I sequences (436 bp) showed a 99.1% match with H. spicifer. As this is the first record of such species in Korea, we suggest a Korean name “Jul-mu-nui-sil-go-gi”.
The purpose of this study was to record for the first time in Korea the presence of Melanoides tuberculata (an invasive alien species), which was confirmed during the “National Survey on the Status of Alien Species” in Jukdang stream (also known as Guppy Stream, located in Icheon, Gyeonggi Province), which is affected by the year-round discharge of heated effluent from a large semiconductor factory and where various tropical organisms, including ornamental fish, appear due to artificial release. A Total of 52 specimens were collected, and they can be visually distinguished from native melanian snails by their reddish-brown flames and spots. Genetic analysis further confirmed the species as Melanoides tuberculate. Melanoides tuberculata typically inhabits tropical climates, but its presence has been confirmed in altered aquatic environments such as Jukdang stream, where the water temperature remains warm even in a temperate climate. This indicates the need for further monitoring of domestic streams with similar conditions, particularly those receiving heated effluent, like Jukdang stream. Additionally, due to its strong reproductive capacity, including parthenogenesis, and its adaptability to various environments, there have been cases where the populations of Pomacea lineata and Aylacostoma tenuilabris have declined. This suggests that Melanoides tuberculata may have a competitive advantage in interspecific competition, potentially suppressing native species populations if it spreads within the domestic ecosystem. Melanoides tuberculata serves as an intermediate host for parasites that can cause diseases in both humans and animals, raising public health concerns in many countries. There is also a significant risk that it could be mistaken for native melanian snail species and consumed, which necessitates a high level of caution.
