Description of the egg sac of Paratrachelas maculatus, with notes on its establishment in urban regions of Germany and Austria (Araneae: Trachelidae)

The as yet unknown egg sac and clutch of Paratrachelas maculatus (Thorell, 1875) is described together with new records of the species from Germany and Austria. The flat, lens-like egg sacs contained 5 to 7 eggs, each approximately 0.75 mm in diameter, and were camouflaged with substrate by the female. Based on known records and locations, the species is most probably established in urban regions of Central Europe.
