Description
This study was carried out for the determination of distribution, abundance, and species richness of hoverflies in the Lakes
Region of Turkey between the years 2014–2016. Samplings were done between April and October of each year. A total of
6595 specimens belonging to 113 species, divided into two subfamilies (Syrphinae and Eristalinae) and 39 genera were
determined. Eumerus bicornis Grković, Vujić et Hayat, 2019; Merodon albidus Šašić Zorić, Ačanski et Vujić, 2020; Merodon
chrysurus Hurkmans et Vujić, 2020; Merodon defectus Vujić, Likov et Radenković, 2020; Merodon longisetus Vujić,
Radenković et Likov, 2020; Merodon obstipus Vujić, Radenković et Likov, 2020 were described as new species for science.
Whereas the most abundant species were Sphaerophoria scripta (29.87%) and Syritta pipiens (17.76%), subdominant species
were Eristalis tenax, Melanostoma mellinum, Eristalis arbustorum and Eupeodes corollae. The majority of species, 89 out
of 113 were recognized as rare (relative contribution 10.72%). Species distribution maps, species richness, abundance, as
well as Shannon–Wiener (H’) index, species seasonal dynamic, and species sex ratio were calculated to indicate the diversity
of Syrphidae species. To obtain present and for the period 2061–2080 species richness patterns and detect areas with the
highest richness, we conducted a Species Distribution Modelling procedure. Considering current potential species richness,
areas predicted to be most suitable for investigated hoverfly species (potentially having 29–37 species) were central-east
and central-west parts of Isparta, as well as southern parts of Afyonkarahisar and northern parts of Burdur provinces. In
the period of 2061–2080, it is predicted that the most suitable areas will shift from Isparta to the north and central parts of
Burdur and to the western part of the Konya provinces. It is hoped that this study will stimulate further studies on the family
Syrphidae in Turkey.
