Turkey, a rich country in the sense of biological variety, is a bridge at the intersection of the Asian, European, and African continents and also has faunal and floral elements of these three continents because of its different climate conditions ( Gülperçin and Tezcan, 2010). Kırıkkale and Çankırı, located in the middle of Central Anatolia, are at the intersection points between east-west and northsouth regarding their topographical structures, climatic conditions, vegetation, temperature, etc. For this reason, effects of the climatic conditions and vegetation of the Black Sea region can be seen in most parts of these regions in addition to their own terrestrial climate ( Sakaltaş Arıyak and Tüzün, 2014). This increases their floral and faunal richness. The Tetrastichinae fauna of Kırıkkale and Çankırı has been identified with this study .

In this study, 209 (151 ♀♀, 58 ♂♂) samples were examined and 37 species were identified. Six species out of 37 identified species in this study were diagnosed from Çankırı, 17 species were diagnosed from Kırıkkale, and 14 species were diagnosed from both provinces. Samples were collected on plants by using a sweeping-net. These samples belong to Anaprostocetus , Baryscapus , Neotrichoporoides , Oomyzus , Pronotalia , Sigmophora , Tamarixia , and Tetrastichus species. Thirteen of them are new records for Turkey (Table).

The Fauna of Tetrastichinae is represented in Turkey (with the addition of the new records in this study) by 147 species in 19 genera, in the Palearctic by at least 903 species in 45 genera, and in the world by at least 1987 species in 109 genera. Turkish Tetrastichinae species are 7.4% of the total Tetrastichinae species in the world and 16.3% of Tetrastichinae species in the Palearctic considering the new records in this study. These rates are relatively low compared to the world and Palearctic regions. More faunistic studies must be conducted in order to discover the full richness of the Turkish Tetrastichinae fauna.

The aim of this study was to contribute to knowledge of the Tetrastichinae fauna and help researchers who are to apply biological control programs using ecological observations related to the samples’ natural habitats and their sampling times.
