Contributions to the tribes Othiini and Xantholinini (Coleoptera: Staphylinidae: Staphylininae) of Türkiye from the Aegean Region

Abstract

The main object of this study is to make contributions to the Staphylininae (Coleoptera: Staphylinidae) fauna of Türkiye with additional records from tribes Othiini and Xantholinini and a new species of Xantholinus Dejean, 1821. Examined material was composed of specimens collected from the Aegean Region between 2019–2022. A total of 18 species were recorded, belonging to nine genera and two tribes. Three of these are new records for Aegean Region. Furthermore, a new species, Xantholinus (Calolinus) manisaensis sp. n., is described from Manisa province. Description of the new species, photographs of habitus, genital segment and aedeagus as well as a differential diagnosis are also provided. The global distributions of the above species are included, and the zoogeographic status of each species is discussed. Previous records from the study area are compared to and evaluated with our findings. The majority of the collected species were European and Asian in distribution, reflecting the regional character and geographical position of Türkiye. It can be concluded that climate change has negatively affected biodiversity and with species loss as a possible result.
