Polyphylla laticollis manchurica Semenov, 1900, is a critically endangered species in the Republic of Korea and is strictly protected as a Class I endangered species. Although this beetle species faces a threat of extinction, its ecological understanding is limited. Previous studies conducted on this species in the Republic of Korea have focused only on its taxonomy and mitochondrial genome sequences. Herein, we report an observation of the mating of adults of P. l. manchurica in June 2021, during an ongoing study on Korean beetles. This incidence was reported around light sources from newly constructed townhouses near Geumgang River. Larval habitats were observed along the river between April 2022 and March 2023. Particularly, two larvae were found inside the plant debris, and three were found under the roots of reeds. This study provides key information on the mating ecology of P. l. manchurica that can assist conservation efforts of this critically endangered species.

Planting trees is a very common practice in the coastal dunefields of South Korea as a way to stabilize dune landscapes and protect inland residential areas from strong winds and blown sands. On the other hand, disturbing the original foredune environment may deteriorate the ability of coastal landsto recover from coastal erosion after storms, causing a retreat of coastline. However, there is little information of this sort on the surface of forested dunefields. Airborne LiDAR or drone-based mapping is not easily applicable in such areas. In this study, we developed a digital terrain model of Dasari dunefields, Chungnam Province, based on direct topographic surveys with real-time kinematic GPS and total stations. We also analyzed previous two aerial photographs taken in 1947 and 1966, in order to detect an older landforms of the dunefields. Results suggested that there have been little changes in geomorphology of the Dasari dunefields for the last 50 years, despite continued tree plantings. Today, there are remains of U-shaped structures such as blowouts and parabolic dunes in the dunefields.

A faunistic list and distribution of aquatic beetles were given with two newly records, Copelatus parallelus Zimmermann, 1920 (family Dytiscidae) and Scirtes sobrinus Lewis, 1895 (family Scirtidae) from Nohwa and Bogil islands in South Korea. As a result, a total of 30 species belonging to 24 genera and eight families were recognized: 12 Dytiscidae species, eight Hydrophilidae species, three Haliplidae species, two Scirtidae species, two Gyrinidae species, one Noteridae species, one Elmidae species, and one Psephenidae species. Composition and habitus photographs of all collected aquatic beetles, habitats, and the diagnostic characters of C. parallelus and S. sobrinus are provided.

The family Trogossitidae Latreille occurs worldwide, including some Pacific islands. The family contains about 50 genera and 600 described species, and the group was recently classified by Kolibáč into three subfamilies, Lophocaterinae, Peltinae and Trogossitinae. Among the lophocaterine genera, a genus Ancyrona Reitter includes 62 species in most parts of the world except the Nearctic region, and is divided into five informal species groups by Kolibáč. In this study, the genus Ancyrona and its a single species, A. diversa (Pic), is newly reported in the Korean fauna. A diagnosis, habitus photographs, and illustrations of female diagnostic characters are provided, with a key to Palaearctic species of the genus Ancyrona.

The subgenus Abstrulia Casey belonging to the genus Tetratoma Fabricius of the family Tetratomidae is distributed ten species over the Holarctic region, including eight Palaearctic species. In East Asia, four species from Russian Far East and two species from Japan have been recorded, respectively. In the Korean Peninsula, two species, T. (A.) ainu (Nakane) and T. (A.) pictipennis Reitter, were reported up to date, and latter species is newly recorded in South Korea in this paper. A redescription, habitus photograph, and illustrations of diagnostic characters of the species are provided, with a key to species of the subgenus Abstrulia.

The genus and species, Diekeana insignis(Gorham), is reported for the first time in Korea. Male adults were collected from Geoje Island and Changwon-si, located in the southern part of South Korea. The species of D. insignis(Gorham) is characterized by the following morphological characteristics: body length about 9.4mm; pronotum with transverse black marking in the middle part; each elytron with seven large black markings; penis long, slightly bent at apical part, truncate at apex; parameres narrow and as long as penis guide; penis guide narrow and pointed at apex. We herein provide habitus photographs, illustrations of morphological characters, male genitalia, and a detailed diagnosis. A partial sequence of the mitochondrial COI gene was obtained and provided mtDNA information for this species.

The genus Hydroporus Clairville is the most diverse group belonging to the subfamily Hydroporinae in the family Dytiscidae. However, members of this group have not been recorded in the Korean peninsula. The genus Hydroporus Clairville is characterized by the following features: body glabrous to distinctly setose; elytra and ventral surface mainly piceous to black; epipleuron lacking a carina on humeral angle; metacoxal process conjointly with hind margin straight or slightly angulate medially. We collected the high mountain wetland and identified the species of Hydroporus uenoi Nakane based on male genitalia for the first time. A habitus photo, a redescription, mitochondrial DNA sequence, illustrations of the aedeagus of species, and habitat information are provided.

The beetle family Georissidae, represented by Georissus kurosawai Nakane, is identified for the first time in Korea. Worldwide, the family Georissidae Laporte contains 83 described species in the only genus Georissus Latreille. This beetles usually inhabits sandy or muddy banks of streams, rivers, and standing water, and some species live in tidal flats and leaf litter. Mostly, adults are covered by a layer of mud or sand grains dorsally and are attracted to light. They are characterized by the combination of the following characters: prosternum reduced, procoxae enlarged, metacoxae separate, ventral hydrofuge pubescence absent, elytra punctatostriate and without scutellary stria, metathoracic anepisterna concealed, and sternite III enlarged.

안재홍의 '불함도(不咸道)'의 핵심은 ? ? 배어 원칙(原則)'인바, 이는 '다사리 국가론(國家論)'의 토대가 된다. 안재홍의 '다사리 국가론'은 우리말 숫자의 의미를 어원적으로 해명하고, 그에 정치철학적 의의를 부여한 것이다. 안재홍이 특히 주목한 우리말 숫자는 '다섯'으로서, 그의 '다사리 국가론'도 여기에 근거하는 것이다. 그에 의하면 '다섯'은 '다사리'로서, 여기에는 '모든 사람이다 말한다'는 뜻과 '모든 사람을 다 살린다'는 뜻이 담겨 있다. 안재홍의 정치적 노선은 '좌 우의 대립을 지양시켜 통일민족국가를 건설하려는 것'이었던바, 이를 위해서는 '대립의 지양회통 논리'와 '새로운 나라의 전망'을 제시해야만 했다. 안재홍은 우리말 숫자의 어원(語源) 해석에서 이두 요소를 찾아내고, 이를 '조선정치철학'으로 체계화시킨 것이다. '조선인은 조선의 정치철학에 입각하여 국가를 건설하는 것이 가장 바람직하다' 는 주장에는 많은 사람들이 쉽게 동의할 것이다. 이러한 맥락에서, 안재홍은 정치적 정당성의 근거를 우리 민족의 전통에서 찾음으로써, 한편으로는 左 右의 대립을 지양시키려고 했고, 한편으로는 자신의 정치 노선에 대한 대중적 지지를 확보하려고 했던 것이다.
