About Gomphus schneiderii Selys, 1850
Gomphus schneiderii, commonly known as the Turkish clubtail, is a species of dragonfly. It is closely related to the Common Clubtail, Gomphus vulgatissimus, and has sometimes been classified as a subspecies of Gomphus vulgatissimus. This species is distributed across the southern Balkan Peninsula, Turkey, and Iran; its range overlaps with that of Gomphus vulgatissimus in eastern Transcaucasia. The two species can be told apart by examining the male genitalia of specimens.
