Distribution of the genus Pellenes Simon, 1876 (Araneae: Salticidae) in Poland. The article presents almost one hundred new localities of Pellenes nigrociliatus and P. tripunctatus. The preferred habitats of both species in Poland are dry stony or sandy areas with sparse vegetation. Their presence is strongly connected to the distribution of land snails, whose empty shells are used as a shelter and breeding place. Frequent observations on railway embankments suggest that their distribution in Poland may be much wider than previously thought and that the railway lines may play a key role as routes for their dispersal.
