A taxonomic review of Atheta Thomson subgenus Atheta Thomson in the Korean Peninsula is presented. The subgenus is represented in Korea by eight species including two new species: A. (A.) prolixa Lee & Ahn, sp. nov. and A. (A.) vegrandis Lee & Ahn, sp. nov. Atheta (A.) sauteri Bernhauer is reported for the first time in South Korea. A key, habitus photographs and illustrations of the diagnostic characters are provided.

A taxonomic study of Korean Notothecta Thomson is presented. Two species are recognized [N. effecta (Sawada) and N. watanabei (Sawada)] and a new synonym, Atheta (Atheta) taesongsanensis Paśnik = N. watanabei (Sawada), is proposed. Notothecta effecta is reported for the first time in the Korean peninsula. A key and illustrations of diagnostic characters are provided.

To explore the origins of coastal colonization within the tribe Athetini Casey, we present a revised molecular phylogeny. The dataset comprised partial mitochondrial COI, COII, 16S rDNA, NADH1, partial nuclear 18S rDNA and 28S rDNA. We chose a total of 95 species in 51 genera, including 14 coastal species in eight genera and 21 outgroup species. The ecological association of species with a coastal habitat was mapped onto a phylogeny to assess the evolution of habitat specialization in the Athetini lineage. The results reveal that five independent origins (clades A–E) of coastal colonization have occurred throughout the tribe Athetini. The following changes in classification are proposed: (i) Adota minuta Lee and Ahn is removed from the genus Adota and tentatively included in Atheta (Badura); (ii) The genus Saphocallus Sharp is transferred from Athetini to Geostibini.

한국 농촌 경관은 논과 밭을 중심으로 넓은 경작지와 함께 숲이 어우러진 다소 복잡한 경관구조를 나타내고 있으며 숲은 농경지와 산림 서식지 간 생물 이동과 종자 전파를 원활하게 하는 생태통로와 징검다리 역할을 함으로써 피난처 역할을 수행하는데, 이 연구에서는 곤충 개체군의 이동 현상을 파악하기 위한 기초연구로 각 서식지 간 다양성 양상을 시공간적으로 살펴보았다. 조사는 충남 (금산)과 충북 (옥천), 전남 (해남, 영광) 등 4지역에서 2014년 3월부터 8월까지 실시하였으며 나방은 자외선등 트랩을 딱정벌레는 함정트랩을 설치하여 채집하였다. 딱정벌레는 35과 225종 2,457개체, 나방은 17과 141종 403개체가 채집되었으며 지역별로는 딱정 벌레 종 수와 개체수 모두 충청지역에서 높은 값을 나타내었 으나 나방은 두 지역간 차이를 나타내지 않았다. 서식지 유형별 종 수와 개체수 양상은 산림에서 가장 높았고 다음으 로 과수원, 논 순이었다. 서식지 간 식성의 차이를 살펴본 결과 산림에서는 초식성곤충이 과수원과 논에서는 포식성 곤충 출현비율이 높은 경향을 나타냈다. 나방은 전남과 충청의 출현이 동일한 반면 딱정벌레는 시간차이가 있는 것으로 나타났으며 서식지별로 숲, 과수원, 논 등에서 모두 봄과 여름에 증가하는 추세를 보였으나, 논에서는 늦여름에 많은 개체가 확인되었다. 딱정벌레 역시 나방과 유사하였지만 숲에서 과수원이나 논보다 늦게 개체수가 늘어나는 양상을 나타내었다. 추후 농경생태계 내 다른 서식지 형태 사이에서 분류 군의 출현양상에 대한 장기간 조사를 통하여 이번 연구에서 얻어진 결과에 대한 면밀한 검토가 필요할 것으로 생각한다.

Despite the enormous ecological success of insects elsewhere on earth, they have failed to colonize oceans. A significant portion of the marine littoral insect fauna consists of Coleoptera and the highest number of species belongs to the beetle family Staphylinidae. At present, over 400 species in 91 genera and eight subfamilies are confined to marine coastal habitats. Coastal Staphylinidae are polyphyletic, and have diverse adaptations of structure, physiology, and behavior. Aleocharinae contain the largest number of coastal species (about 200 species in 46 genera). Today I would like to briefly introduce my research program on the diversity, phylogeny, habitat evolution, and historical biogeography of the coastal Aleocharinae. Three selected aleocharine lineages containing many coastal species published with my colleagues are provided.

The genera Acruliopsis Zerche and genus Xylodromus Heer contain four species and 13 species worldwide, respectively. In East Asia, all species of Acruliopsis are distributed and two of Xylodromus are described, which are new to the Korean Peninsula. Little is known about the habitat of Acruliopsis species, but our specimens were collected under bark of log or by flight intercept trap. The Xylodromus species is found in leaf litter of forest, in nests of the mammals or birds, or sometimes in granary. In this paper, we report Acruliopsis ussuriensis Zerche and Xylodromus daimio (Sharp) for the first time in the Korean fauna. We provide the habitus photographs, illustrations of diagnostic features and a key to the genera of the tribe Omaliini MacLeay in Korea.

A cladistic analysis of the subtribe Homalotina Heer is presented. They are hypothesized to be a monophyletic group consisting of nine genera (Anomognathus Solier, Cephaloxynum Bernhauer, Holisomimus Cameron, Homalota Mannerheim, Neomalota Cameron, Stenomastax Cameron, Thecturota Casey, Homalotina gen. 1 new genus, Homalotina gen. 2 new genus), based on two synapomorphies: complete postoccipital sutures on head and macrosetae present on postero-lateral margin of metacoxa. The data set for phylogenetic analysis comprised 83 characters representing 248 character states derived from adult morpholgy. These data were analysed using equal weighting (EW) and implied weighting (IW) (k=1– 6) and supported the monophyly of the subtribe based on two unique characters (complete postoccipital sutures on head and macrosetae present on postero-lateral margin of metacoxa) and two homoplastic characters (head as wide as pronotum and antennal insertion on head slightly anterior to a line drawn between anterior margin of eyes). The topology of the IW trees with k=2–4 was the same and differed with the EW trees. The clade (Homalotina sp. 3 (Homalotina sp. 1, Homalotina sp. 2) was supported in all analyses and the clade ((Neomalota (Homalota flavomaculata (Stenomastax nigrescens, Stenomastax sp. 1))) was supported in all analyses except for the IW (k=2–4). The monophyly of genus Homalota was not supported at all and genus Stenomastax formed a monophyletic group only for the IW (k=2–4) resulting in a new combination [S. flavomaculata (Bernhauer) comb. nov.]. Also, we present two new genera resulting in two clades (Homalota intrusa, Homalota sp. 1) and (Homalotina sp. 1, Homalotina sp. 2)

Coastal Bryothinusa Casey, the most species rich genus among all the coastal aleocharine genera, contains 30 species worldwide. Members of Bryothinusa occur along the coasts of the Pacific and Indian Oceans including their neighboring seas. In Korea, four species were recorded from the western and southern coasts of the Korean Peninsula by Ahn and Jeon and most species are found mainly under stones, seaweeds, and debris on mud flats and sandy beaches. While studying the Korean coastal Staphylinidae, we have accumulated sufficient specimens of Bryothinusa species that look different with the known species previously. After examining the specimens thoroughly, we identified them as two new species including one species new to the Korean fauna. They correspond well to the diagnostic characters of Bryothinusa: body parallel-sided; labrum as long as wide; mandible elongate; lacinia with setae interdigitating with spinose scales; lacinia and galea remarkably elongate; ligula short, not divided; anterior angles of mentum prolonged into spinose processes, two long medial setae present on mentum; mesocoxal cavities very closed, not margined posteriorly; mesoventral process sharply pointed; tarsal formula 4-4-5; apical lobe of paramere long. A total of seven species including two new species and one species newly recorded in Korea are recognized. Here, we describe two new species (B. brevipennis and B. littoralis) with illustrations of diagnostic characters, compare the new species with related species, and report B. algarum Sawada for the first time in Korea.

The coastal Aleochara fucicola Sharp species complex include A. fucicola Sharp, A. hayamai Yamamoto and Maruyama, A. puetzi (Assing), and A. segregata Yamamoto and Maruyama. To clarify the delineation and phylogenetic relationships of the A. fucicola species complex, we conducted phylogenetic analyses based on molecular characters and detailed morphological characters by using scanning electron microscopy (SEM) images. The dataset comprised two mitochondrial (cytochrome c oxidase I and COII) and three nuclear protein coding genes (CAD, EF1-a, and Wingless) for 34 populations of four species of A. fucicola species complex. We found strong disagreement between mitochondrial and nuclear gene trees. Two species, A. puetzi and A. segregata, were not distinguished by mitochondrial DNA data, but distinguished by nuclear DNA data and SEM characters. A multilocus phylogeny and SEM images revealed four well-supported species lineages. Based on a multicolus phylogeny and SEM images, we conclude the following the taxonomic status of the Aleochara fucicola species complex with four species (A. fucicola, A. hayamai, A. puetzi, and A. segregata).

The Gyrinidae are water beetles with very unique lifestyle - adult rapidly gyrate and whirl on surface of water hunting for prey. They are found in stagnant or slowly running water and prefer clean oxygen-rich habitats. Members of the family are characterized by the following characters: compound eyes divided completely with one pair on the dorsal surface of the head (above the water line) and another on the ventral surface of the head (below the water line); antenna short with a broad, cup-shaped scape, subtriangular pedicel and elongate but compact flagellum; meso –and metathoracic legs broadly expanded and fringed with setae for swimming. In this paper, a taxonomic review of the Korean Gyrinidae Latreille is presented. Seven species in three genera are recognized, one of which (Gyrinus pullatus Zaitzev) is reported for the first time in South Korea. We also discovered that G. curtus Motschulsky previously recorded in Korea was misidentification of G. japonicus Sharp. Habitus photographs, keys, redescriptions, and diagnostic characters with illustrations of the species are provided. The specimens used in this study are deposited in Chungnam National University Insect Collection (CNUIC), Daejeon, Korea.

The genus Paraloconota was described as a subgenus of the genus Atheta by Cameron (1939) including seven species and he noted that it is similar to Aloconota Thomson, but can be distinguished by transverse impression of abdominal tergite IV and absence of tubercle of male tergite VII. Since then, Coiffait (1982) first treated it as a genus and described a new species. Pace (1993) proposed it as a subgenus of the genus Liogluta Thomson, 1858. Later, however, he (1998) treated it as a different genus related Liogluta. Smetana (2004) followed Coiffait (1982) and Pace (1998), and listed a subgenus Paraliogluta Pace of Liogluta as a synonym of Paraloconota. Members of the Paraloconota can be distinguished from other aleocharine genera by combination of the following characters: infraorbital carina incomplete or absent; labium with ligula divided in 2 lobes at base, lateral pseudopores absent on prementum; mesoventral process reaching to half length of mesocoxae, pointed at apex; metaventrite not produced between metacoxae narrowly separated; pubescence relatively long; legs long; empodial seta distinctly longer than claw; male tergite VII without tubercle; median lobe of aedeagus narrow apically in ventral aspect. (Cameron 1939, Pace 1991) The genus Paraloconota contains 26 species with a limited distribution in the East Palaearctic and Oriental regions (Smetana 2004) and they are usually found in the long moss attached to boulders in swiftly running mountain streams (Cameron 1939). While studying on Korean Athetini, the genus Paraloconota and a new species, P. koreana sp. n., are identified for the first time in Korea. Also we found that they are in agreement with the diagnostic characters of the tribe Geostibini Seevers, 1978 presented by Elven et al. (2012). In this study we transfer from Athetini to Geostibini and provide a habitus photograph and illustrations of the diagnostic characters of Paraloconota koreana sp. n..
