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.

A taxonomic review of the Acrotona Thomson in Korea is presented. The genus is represented in Korea by 10 speciesincluding two new species, A. koreana Lee & Ahn, sp. nov. and A. rufescens Lee & Ahn, sp. nov. Two other species,A. paeksongrica Paśnik and A. suyangsani Paśnik, are synonymized under A. pseudotenera (Cameron) and A. lutulenta(Sharp), respectively, and four species, A. grata (Cameron), A. lutulenta (Sharp), A. pseudotenera (Cameron) and A. vicaria(Kraatz), are identified for the first time in South Korea. A key to the Korean species and illustrations of habitus anddiagnostic characters are provided for the new species.

A taxonomic study of Korean species of the geostibine genus Aloconota is presented. The genus is represented in Korea by seven species including five new species, A. brunnea Lee & Ahn, sp. n., A. hydrosmectoides Lee & Ahn, sp. n., A. impressa Lee & Ahn, sp. n., A. parviocularis Lee & Ahn, sp. n. and A. tuberculata Lee & Ahn, sp. n. A key to the Korean species and illustrations of diagnostic characters are provided.

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.

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 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..
