In this study, distribution of Steninae (Coleoptera: Staphylinidae) subfamily in Turkey was comprehensively evaluated and compared with the fauna of Turkey's neighboring countries and the Palaearctic Region. The current literature indicates that there are 130 Steninae species in Turkey, and approximately 17.5% (23 species) of these species are endemic to Turkey. This study presents the results of an analysis of the similarity between Turkey and its neighboring countries and the Palaearctic region. The Black Sea region has the most species (87 species) and the highest number of endemic species (15 species) in Turkey. An analysis of the similarity between Turkey's regions revealed that the Central Anatolia Region and the Eastern Anatolia Region are the most similar to each other, with a similarity rate of 75%. In terms of similarity with other countries, the Steninae fauna of Turkey is most similar to that of Greece and Bulgaria, with a similarity rate of 43%. Compared to other sub-regions of the Palaearctic, the Steninae fauna of Turkey is more similar to the Middle Eastern fauna, with a similarity rate of 29%.
