With literature sources, a total of 86 species of the genus Hylaeus Fabricius, 1793 from 10 subgenera are compiled for Turkey. New for Turkey are 11 species: Hylaeus (Dentigera) kahri Förster, 1871, H. (Dentigera) pallidicornis Morawitz, 1876, H. (Hylaeus) deceptorius (Benoist, 1959), H. (Hylaeus) gracilicornis (Morawitz, 1867), H. (Hylaeus) paulus Bridwell, 1919, H. (Hylaeus) trisignatus Morawitz, 1876, H. (Nesoprosopis) pectoralis Förster, 1871, H. (Prosopis) incongruus Förster, 1871, H. (Prosopis) trinotatus (Pérez, 1896), H. (Prosopis) variolaris Morawitz, 1876 and H. (Spatulariella) sulphuripes (Gribodo, 1894). No new specimens could be found of 13 species which had been detected formerly. Our knowledge on the distribution of numerous species is greatly expanded. The characteristics of distribution are defined for the individual species. For example, H. meridionalis is the most widespread with records from 46 provinces covering all geographical regions of the country, while many other species are only known from one province, sometimes from a single record.
