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 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..
