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.

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.

Understanding the landscapes and the elements that make up the landscapes can help us understand the entire natural ecosystems and biodiversity. Landscape ecology has been studied since the past. however, many studies are conducted on single landscapes, and comparative studies between landscapes are few. We compared insect species diversity and community structure within a single plant community across landscapes and habitat. Additionally, identify environmental factors that affect diversity. Our results showed that above-ground and below-ground insect communities were clearly distinguished. Additionally, species diversity was high below-ground in all landscapes. Insect community structures across landscapes did not differ in above-ground. However, below-ground, the urban was differentiated from the forest and agricultural land. We identified the urbanization indices GMIS and PHBASE as factors responsible for these difference.
