Nicrophorus Fabricius, 1775, commonly known as necrophagous beetle, is associated with vertebrate carrion. Up to date, the genus consists of 72 species worldwide. In recent years, various phylogenetic studies explored on the evolution and relationship of the species in the genus. However, morphological and molecular phylogenetic studies produced conflicting results, continuing the problem over whether Nicrophrous quadraticollis is monotypic or not. The present study is to report the complete mitochondrial genome (mitogenome) of N. quadraticollis that was sequenced in prior to a systematic research of Silphinae. It was 17,747bp in length and comprised 12 protein-coding genes(PCGs), 2 rRNA Genes, 22 tRNA Genes and one non-coding region. The nucleotide composition is 40.9% for A, 36.7% for T, 9.0% for G and 13.4% for C.

The genus Anaclasiger which is one of the myrmecophilous beetle (Clavigeritae) was described by Raffray in 1890 with the type species, A. sinuaticollis. Since then, only one species, A. zhudiae, had been added in this genus. The former species has known to distribute in Singapore (type locality), Taiwan (Raffray, 1914), Malaysia (Nomura & Idris, 2005), Thailand and Japan (Nomura et al., 2006), and the latter has been reported only in China (Yin et al., 2012). During specimens research of Korea National Arboretum, we were recognized one species, A. sinuaticollis, collected by pitfall trap in Mt. Geombong. Therefore, we are going to report this unrecorded genus and species for the first time from Korea. Both the information of the species including diagnosis, habitus and male genitalia, and that of the genus distribution on the map are going to be provided.

The genus Cephennodes Reitter (Coleoptera: Staphylinidae: Scydmaeninae) comprises approximately 220 species worldwide within three subgenera (Cephennodes, Aculeodes, Fusionodes). In Korea, two species are recorded: C. (s. str) japonicus (Sharp) and C. (Fusionodes) graeseriReitter. The two subgenera, Cephennodes and Fusionodes, can be distinguished by the form of the parameres in relation to the median lobe, whether fused or divided. In this study, we redescribed two species: C. (s. str) japonicus and C. (Fusionodes) graeseri. Additionally, Cephennodes (Fusionodes) ussuricus (Kurbatov) is recorded first time in Korea. Images of habitus, aedeagus, and a distribution map are provided.

The tribe Bythinini Raffray is species-rich pselaphine group including over 600 species distributed worldwide. Despite its diversity, only one genus, Bryaxis Kugelann, has been reported in Korea. In this study, we newly describe Bryaxis sp. n. mainly based on the male antennal modification. We also report a new species of the genus Tychobythinus Ganglbauer from Korea. Members of these two bythinine genera are commonly characterized by the traits of maxillary palpi: elongated second palpomere, shortened penultimate, and enlarged last one. In addition, we conducted phylogenetic analyses to demonstrate the relevance between antennal modification and evolutionary relationship of Bryaxis. To perform the phylogenetic construction, we assembled three mitochondrial genes (cox1, cox2, and 16S) and three nuclear genes (18S, 28S, and wingless) into a dataset. Eleven species of Bryaxis and two Tychobythinus species are included, the latter genus of which are used to root the consensus trees.

Six new species are described that are members of the New Zealand endemic genus Adalmus Reitter (Staphylinidae: Pselaphinae: Euplectitae: Trichonychini: Panaphantina): A. bullerensis sp. nov., A. kanierensis sp. nov., A. karekarensis sp. nov., A. mangamukaensis sp. nov., A. puberilumbus sp. nov., and A. serrilumbus sp. nov. In addition, Dalmisus Sharp is placed as a junior synonym of Adalmus (gen. syn.) and the species Dalmisus batrisodes Sharp, 1886, Plectomorphus longiceps Broun, 1913 and P. longipes Broun, 1912 are placed as junior synonyms of A. velutinus Reitter, 1885 spp. syn. Also, P. rugiceps Broun, 1921 is transferred to the genus Adalmus, comb. nov. Adalmus now holds eight species.

Necrophila (Calosilpha) brunnicollis brunnicollis (Kraatz, 1877) is a common necrophagous beetle in the Palaearctic region. The species is often encountered on the corpses of large vertebrates, such as human and pig, and is well recognized as a potentially group of beetles in forensic entomology. All of the developmental stages can be found in the corpse and under the soil near a corpse, which can be used to reconstruct the site, such as estimating PMI(Postmortem interval). However, its larval instar stages were never thoroughly described for identification. In this study, we redescribe the morphological characters of all larval stages of N. brunnicollis for quantitative and qualitative morphological information. In addition, we provide the images of larvae and an indentrifiaction key to larval instars.

The genus Silpha Linnaeus, 1758 in Silphinae includes 33 species worldwide. This group is flightless and known to feed on invertebrate carcasses from the ground surface. In South Korea, 3 species have been recorded, and S. koreana Cho& Kwon, 1999 is an endemic species, distributed only Mt. Taebaek and Mt. Mindung. Up to date the immature stages of the species has never been studied although the species has significant value as an endemic species. The present study is the very first one ever conducted describing the larval morphological characters of S. koreana along with images of larval stages. Furthermore, we report observations on developmental lengths for each stages of the species.

Goniaceritae is the most speciose supertribe of the subfamily Pselaphinae with more than 3,000 species worldwide. Brachyglutini is the only tribe within New Zealand Goniaceritae, comprised of 8 genera. Physobryaxis Hetschko is monotypic genus of the subtribe Brachyglutina. Although the adults of P. inflatus is close to the members of genus Gastrobothrus Broun, 1882, it is characterized by median antebasal fovea and antebasal sulcus on pronotum. In this study, we report six species of Physobryaxis examining 21 specimens. Illustrations of the habitus, diagnostic characters including male genitalia, and key to the species are also provided. Additionally, we present a distributional map divided into areas based on Crosby’s code.
