Hitchhiker insect species from international vessels entering Korea in 2022 were monitored. A total of 947 samples of hitchhiker insects were collected using a simple collection method by hand. Among them, 856 individuals were classified as 374 species of 86 families in 10 orders through integrative analysis with DNA barcoding and morphological examination. The rest 91 individuals were identified only to the family level. As a result of examining the distribution of the 374 species (856 individuals), 38 species (71 individuals) were confirmed as not-distributed species in Korea, including six species (11 individuals) as 'regulated species' listed by the Korean Animal and Plant Quarantine Agency. Of 38 not-distributed species, 10 species were detected multiple times (at least twice). Accordingly, it is necessary to strengthen monitoring of the area around the port of entry along with continuous surveillance to prevent invasion of species detected multiple times. For monitoring alien hitchhiker insect species, this study provided detection information and biological data for alien species.

We monitored the hitchhiker insect pests from the international vessels entering into Korea in 2021. As a result, total of 581 individuals were detected by the survey based on visual inspection with naked eye. Among them, 500 individuals were identified as 244 species of 65 families under 11 orders through the integrative taxonomic method with DNA barcoding and morphological reexamination, but the remaining 81 individuals were classified as only to the family level. Of the 244 species identified, 26 species were determined to be not-distributed species in Korea (two Orthoptera, two Hemiptera, one Megaloptera, five Coleoptera, three Hymenoptera, and 13 Lepidoptera). Among them, two species, Sagra femorata (Chrysomelidae, Coleoptera) and Dendrolimus punctatus (Lasiocampidae, Lepidoptera), were discovered as 'Regulated species' listed by Animal and Plant Quarantine Agency, South Korea. Therefore, we reported on the 26 not-distributed species in Korea and provided inanimate pathway information such as navigation routes on the vessels hitchhiking the species, state of the samples at the time of detection, identification results and original distribution for the detailed monitoring and the risk analysis on the species.

On the Korean Peninsula, eleven species of the genus Liparis (Orchidaceae) have been recorded, and three species are presumed to belong to the L. makinoana complex. These are L. koreana, L. japonica, and L. makinoana. Liparis japonica and L. makinoana are distributed in South Korea, but the distribution of L. koreana has not been confirmed. Liparis japonica and L. makinoana are morphologically very similar, making it difficult to classify them. Recently, L. japonica and L. makinoana in Japan were reclassified into three species. One of them is an amended species of L. makinoana, and the other two species were described as new species, specifically L. longiracemosa and L. suzumushi. It was confirmed that the three species are distributed in South Korea. Here, we provide a distribution map, photographs of the three new species, and a comparison of their morphological characteristics.

(1) 1966年 5月 25日부터 1967年 8月 30日에 이르는 사이에 江原道高城郡懸內面松峴里에서 三陟郡近德面草堂窟에 이르는 嶺東地方에서 10箇 河川을 調査하여 40種의 淡水魚를 採集, 또는 確認하였다. 이 중, 32種은 이 地城에서는 未記錄種이다. (2) 이들 40種 중, 元山 以北에서 産出되지 않은 것이 14種이고, 漢江에서 棲息하지 않은 것이 17種이었고 蔚珍以南의 상도 慶尙道 東部에서 發見되지 않은 것이 11種 이다. (3) 嶺東地域에서 産出되지 않은 淡水魚로서 元山 以北에 棲息하는 것이 33種, 蔚珍 以南에서 發見되는 것이 16種, 漢江에서 採集되는 것이 60種이다. (4) 本區域은 淡水魚 分布上 Amur 亞區와 中國亞區의 中間型을 나타내고 있으며, 南北과 東西間의 差異는 各各 生態的 條件과 地域的 要因의 差異에 緣由하는 것으로 思料된다. (5) 本區域에서 産出되는 淡水魚 중, 分布上 特히 注目되는 것은 Ganthopogon strigatus, Cobitis rotundicaudata, Coreoperca kawamebari, Leucopsarion petersi 等이며, Gobiogobio, Pseudorasbora parva, Zacco paltypus, Zacco temmincki 等이 採集되지 못한 것은 意外이였다.

Pinus densiflora stands are common secondary forest communities on infertile soils in Korea. The stands are results of long severe past biotic pressure such as cutting, burning and grazing. These could be regarded as biotic climax in Korea. Because of their prevalent occurrence, relatively simple species and age composition, and their domestic economic importance, study of their distributional patterns may give some basic knowledge for better utilization of land resources in Korea. To detect distributional patterns and interspecific associations ten pine stands, each of which was homogenious with respect to topography and physiognomy, were subjectively selected from pine stands in Kyunggi Province near Seoul in 1969 and were made object of this study. Four contiguous systematic samples of count for trees, shrubs and seedlings from belt transects were collected from homogeneous areas within ten natural pine stands. The belt transect was 64m or 128m in length, and 1m, 2m or 4m in width. Basic units within the transect ranged from 64 to 256. The data from the contiguous transects were analysed in terms of multiple split-plot experiment. Departure from randomness of stem distribution, i.e., pattern, was tested in terms of variance mean ratio. For the detection of association between species, correlation coefficient was calculated for different block sizes. The values of ${\gamma}$ were tested by the usual t-test. Fine trees within one of the stands showed significant regular distribution through out the blocks. Within other eight stands pines were randomly distributed at basic unit with 4$\times$4m, 2$\times$2m, 2$\times$1m and 1$\times$1m. One significantly clumped distribution at basic unit 2$\times$2m, however, was observed from one of the pine stands. These randomly distributed groups were themselves significantly regularly distributed throughout the blocks for four pine stands. For the other four pine stands, in addition to the random distribution at the basie unit(the primary random group), randomly distributed groups with 32m dimension(the secondary random groups) were also observed. Both the primary and the secondary random groups were significantly regularly distributed at the rest of blocks. Pine seedlings were not distributed randomly thoughout the blocks. Within three of the ten stands they were contagiously distributed. Important shrub species underneath pines such as Querus serrata, Q. acutissima, Leapedeza intermedia, Rhododendron Yedoense var. poukhanenae, Juniperus utilis, Rhododendron mucronulatum var. ciliatum shnwed consistently similar distributional pattern with the pine at each stand. The shrub species pairs; Rhododendron Yedoense var. poukhanenae/Quercus serrata, Rhododendron mucronulatum var. ciliatum/Lespedeza intermedia were significantly negatively associated from 1m to 4m dimensional block sizes but became significantly positively associated from 8m sized blocks on. On the other hand the shrub species pairs; Lespedeza intermedia/Robinia Pseudoacacia, and Lespedeza bicolor var, japonica/Lespedeza intermedia were also significnalty negatively associated from 1m to 8m sized blocks but became significantly positively associated from 16m sized blocks on. The associational pattern between Rhododendron mucronul tun var. poukhanenae and Lespedeza intermedia was not consistent throughout the stands. In some stands negative associations were observed throughout the blocks except NS 32. From these observatons micro-edaphic variation within the pine stands seems not to be great enough to cause distributinal difference of pine trees within the ten pine stands. Among each species and pine seedings, however, the edaphic variation within the pine stands may be great enought to cause distributional variation.

A new species of the genus Biemna(Demospongiae: Poecilosclerida: Desmacellidae), Biemna hongdoensis n. sp. was collected from Hongdo Island, Korea by SCUBA diving in 2004. B. hongdoensis n. sp. is closely related to B. megalosigma Hentshel, 1912 in their spicules, but the styles and sigmas of new species are larger than B. megalosigma's and microxeas and raphides of new species are smaller than B. megalosigma's. Also, new species has not spheres. The stubby conulose are distributed throughout the surface of new species.

3종의 외국산 따개비가 한국의 조간대 해역에 침입한 것이 발견되었는데 이들은 Balanus amphitrite, B. eburneus 및 B. improvisus이다. 한국내에서 이 3종이 모두 발견되고 개체군이 가장 발달된 곳은 동남부 해역, 즉 부산 부근이다. B. amphitrite는 1970년도 초에 가장 먼저 한국에 침입한 것으로 추측되며 가장 널리 분포해 있으나 목포 이북의 서해에는 아직 침입해 있지 않은 상태이다. B. improvisus는 동해의 복쪽까지 확산해 있으나 B. eburneus는 동남부 해역에 국한되어 있다. B. amphitrite는 재래종인 B. albicostatus와 경쟁을 하고 있는데 이 두 종이 혼생하고 있는 여러 지역에서 후자의 재래종이 배타되고 있는 실정이다. 서해는 아직 외래 따개비의 침입을 받고 있지 않은데 그 이유는 현재 모르고 있다.

(1) Plants in the crater of Halla-San (Mt. Halla), a conical volcano that originated in the Tertiary period, were studied on three different occasions; July 1937, July 1955, and August 1957, and noted 52 familites, 149 species. In the latest study undergone in 1957, the authors collected 108 species. Notable species among them are Geranium Shikokianum Matsum which has not been reported in Korea, Clematis Chiisanensis Nakai, Lactuca Chelidonifolia Makino, and Platanthera Maximowiczana Schelchter which have not been reported in Jeu-Do(Island) so far. (2) Plants in To-Do(Island), territorial island of Jeju-do, were also studied. The authors noted Canavalia lineata D.C.non-reported Species in Korea, usually distributed along Southern Honshu, Shikoku, and Kyushu of Japna, Ryukyu and Taiwan. The overfall flora of the island is composed of 30 families, 44 Species; 5 Species of wood plants and 39 species of herbs, and is mostly of littoral plants.
