A note on alien spider species from Kosovo (Arachnida: Araneae).

Kosovo is a small landlocked country on the Western Balkans and the youngest country in Europe. In this paper, we report three alien spider species from Kosovo for the first time: Ostearius melanopygius, Parasteatoda tepidariorum and Spermophora senoculata. In addition, we report new records for Pholcus phalangioides for the region. Our investigation is one of the first contributions to the knowledge about the distribution patterns of alien spider species on the Balkan Peninsula. [ABSTRACT FROM AUTHOR]
