강원도 홍천군 규방산에서 채집된 1종의 곤충이 똥풍뎅이과의 똥풍뎅이족에 속하나 비분식성인 신속 및 신종이기에 이를 톱니땅풍뎅이속의 톱니땅풍뎅이(Koreoxyomus koreanus gen. et sp. nov.)로 명명 기재하였다. 아울러 일본산인 Mozartius속에 대하여 분 류학적으로 검토하였는데 이는 본 신속이 이속과 동일한 분류군인 것으로 보이나 Mozartius의 원기재에 기술된 특징이 매우 불완전하며 보충연구나 추가기재도 없어서 정상 적인 분류군명으로 인정하기 어렵기 때문이었다.

A new species belonging to the genus Cyclopinopsis Smirnov, 1935 (Cyclopinidae) is described from Korea, as the third species of the genus. Specimens were collected by washing the subtidal sediments off Dokdo Island in the East Sea and the intertidal sands at Baegripo beach, Taean Peninsula on the Yellow Sea coast. Cyclopinopsis deformata n. sp. is characteristic and distinguished from its two congeneric species currently recognized, C. curticauda Smirnov, 1935 and C. brasiliensis Herbst, 1955 in having a deformed seta at the outer distal corner of the third exopodal segment of leg 4. The seta is supposed to be deformed from an outer spine on the third exopodal segment of leg 4, which has been known as completely lost in the genus until now. A character comparison table of the three species and a key to species of the genus Cyclopinopsis are provided herein.

The family Gracillariidae, belonging to the superfamily Gracillarioidea, is one of the major group of leaf-miners. Among them, the genus Telamoptilia Kumata & Kuroko, 1988 has been known as a small genus with only nine described species over worldwide to date. In this study, the genus Telamoptilia Kumata & Kuroko, 1988, is reported for the first time from Korea. In addition, two species of the genus Telamoptilia, T. grewiae Liu, Wang & Li, 2015 and T. tiliae Kumata & Ermolaev, 1988, are newly recorded in Korea. All the known species are enumerated with their available information. The adults and genitalia of all species are redescribed and illustrated.

The genus Eumetriochroa Kumata & Kuroko, 1988 has been known as a small genus with twelve described species worldwide. In this study, we aimed to review the Korean species of the genus Eumetriochroa of the subfamily Oecophyllembiinae, which belongs to the family Gracillariidae. Three species of this genus are recognized from Korea. Among them, two species, Eumetriochroa araliella Kobayashi, Huang & Hirowatari, 2013 and E. hiranoi Kumata, 1998 are reported for the first time from Korea. All the known species were enumerated with their available information and briefly redescribed for the newly recorded species. The adults and genitalia of all the species are redescribed and illustrated.

The genus Callophyllis is recorded as six separate species with imprecise species delimitation in Korea. To elucidate the species boundaries of Korean Callophyllis, we performed morphological observations and molecular analyses, and included three Japanese Callophyllis species from the type locality. From the results of molecular analyses using plastid rbcL and mitochondrial COI-5P genes, we confirmed ten Callophyllis species, including five cryptic ones: C. adhaerens, C. adnata, C. crispata, and C. japonica from Korea and Japan; C. hayamensis as an unrecorded species from Korea; C. cartilaginea, C. mollitia, C. repens, C. serratifolia, and C. undulata as new species from Korea. There were no Korean specimens that matched C. adnata or C. crispata from Japan, except Korean C. japonica, which formed a genetic group with the Japanese species. We obtained the interspecific divergences among the five cryptic species as 0.6-4.5% in rbcL and 2.8-8.4% in COI-5P. We recognized that the species diversity of Callophyllis has been underestimated from the northwestern Pacific region. The species boundary of Callophyllis from Korea and Japan will be a cornerstone to revealing the phylogenetic affinity of the genus distributed in both hemispheres of the western Pacific.

Coastal dunes must be conserved. Their native halophytes support coastal geography while their symbiotic microorganisms help vegetation thrive. The Goraebul coast has the largest, well-conserved dune system on the East Sea of the Korean Peninsula due to a climax mixed halophyte (C. soldanella, C. kobomugi, and E. mollis) vegetation support. This study identified rhizobacteria and their diversity in mixed halophyte communities unique to Goraebul. Five phyla, 12 genera, and 21 species were identified based on 16S rDNA sequences from 65 isolates. The phylum Bacillota, class Bacillota, order Bacillales, and family Bacillaceae were identified, with Bacillus as the dominant genus (46.15%). The richness and Shannon's diversity were higher at the species than at the genus level due to the dominance of Bacillus; however, various Bacillus species (7) were identified. Therefore, the climax mixed vegetation adapted to the Goraebul coast may exert natural selection pressure in favor of the common characteristics of Bacillus. However, despite this advantage, the Shannon equitability (0.86), Simpson (0.08), and Shannon diversity (2.79) indexes indicate a stable rhizosphere cluster and the climax mixed vegetation is affected by symbiotic relationships between healthy rhizosphere microbiota.

한국에서 채집한 잔디속(genus Zoysia) 식물 종의 유전적 변이를 단순 서열 반복(Inter-Simple Sequence Repeat Markers, ISSR) 마커 시스템으로 조사하였다. 8개의 ISSR 시발체를 이용한 중합효소 사슬 증폭반응에서 86개의 분절의 증폭물을 얻었으며 이 중 76(87.1%)개 분절이 다형성을 나타내었다. ISSR 마커 시스템에서 다형성 정보 지수(PIC)는 0.848이었다. 다형성 대립유전자좌위의 퍼센트(P_p)는 41.2%에서 44.7%까지 나타내었다. 네이(Nei)의 유전자 다양성(H)은 0.149에서 0.186까지 이며 평균은 0.170이었다. 샤논(Shannon)의 정보 지수(I)의 평균값은 0.250이었다. 대립유전자좌위에 근거하여 전체 변이에서 종 간 차이를 나타내는 변이의 몫(G_ST)은 0.601였다. 이는 전체변이의 약 60.1%는 종 간에 있음을 의미한다. 따라서 변이의 약 39.9%는 종 내에 있었다. G_ST에 근거한 유전자 흐름(이동)은 잔디속 간에는 대단히 낮았다(N_m = 0.332). 계통도는 3개의 뚜렷한 분지군으로 분리되었다. 왕잔디(Zoysia macrostachya)와 금잔디(Z. tenuifolia) 분지군, 갯잔디(Z. sinica) 단독 분지군, 잔디(Z .japonica) 단독 분지군이었다. 결론적으로 잔디속 식물에 대한 ISSR 분석은 유전적 변이를 탐지하는데 유용하며, 종을 구분하는 유전자형의 대한 식별력을 주었다.

Our study aimed to investigate the diversity of tintinnid species in Korea by collecting samples from coastal waters. As a result, we identified and redescribed three newly recorded species of the genus Tintinnopsis Stein, 1867 and one previously recorded species of the genus Antetintinnopsis Wang et al., 2021 in Korea. The loricae morphology and molecular phylogeny based on the 18S rDNA sequences of these four were analyzed. Tintinnopsis kiaochowensis Yin, 1956 is characterized by having an irregular collar with spiral turns and an obconical-shaped bowl. Tintinnopsis orientalis Kofoid and Campbell, 1929 is characterized by the inverted bell-shaped lorica with size of 121-140×86-94 ㎛. Tintinnopsis parvula Jörgensen, 1912 is characterized by its narrower collar than bowl and acute angle of the bowl (39-75°). The recorded species, Antetintinnopsis gracilis (Kofoid and Campbell, 1929) Wang et al., 2021 is characterized by a cylindrical collar narrower than the bowl width and with a size of 98-131×37-46 ㎛.

The genera Dero and Allonais belong to the family Naididae. Most species in the genus Dero have unique morphological characters including a branchial fossa and/or gills at the posterior end of the body. The genus Allonais has no eyes unlike its close relative the genus Nais. Of these genera, one species of Dero, D. obtusa, was recently reported in Korea. However, the genus Allonais has not been recorded in Korea. Here, we report Dero dorsalis Ferroni$\grave{e}$re, 1899 and Allonais pectinata (Stephenson, 1910) with a diagnosis and illustrations.
