In Central Europe, as well as in Poland many introduced spider species have been recorded in the past decades. Most of them are from areas with warm climate, and spreading mainly in synanthropic environment, rarely colonizing natural habitats. Results of research, presented in this paper extend the list of Polish synanthropic araneofauna by four species: Latrodectus mactans, Cheiracanthium mildei, Heteropoda venatoria and Heliophanus cf. apiatus. In addition, new findings of rare or rarely collected synanthropic spider species (Nesticella mogera, Scytodes thoracica, Psilochorus simoni, Uloborus plumipes, Parasteatoda tabulata, Steatoda triangulosa, Mermessus trilobatus, Ostearius melanopygius, Hasarius adansoni, Leptorchestes berolinensis, Pseudeuophrys lanigera) are discussed. Presented data enrich our knowledge about distribution of these species in Poland and show new pathways of potential expansion. For Uloborus plumipes and Hasarius adansoni presence of stable, permanent populations is shown. Findings of Mermessus trilobatus and Ostearius melanopygius in open country suggest that these alien species are gradually colonizing natural biotopes.

W Europie Środkowej, w tym także w Polsce, w ciągu ostatnich dekad zanotowano szereg gatunków pająków pochodzących z innych stref klimatycznych, które zostały introdukowanei rozprzestrzeniają się w środowiskach synantropijnych. Zaprezentowane w niniejszej pracy wyniki badań wydłużają listę stwierdzonych w Polsce przedstawicieli synantropijnej araneofauny o cztery gatunki: Latrodectus mactans, Cheiracanthium mildei, Heteropoda venatoria oraz Heliophanus cf. apiatus. Oprócz tych gatunków omówiono nowe stanowiska sporadycznie lub rzadko dotychczas wykazywanych w Polsce pająków synantropijnych takich jak: Nesticella mogera, Scytodes thoracica, Psilochorus simoni, Uloborus plumipes, Parasteatoda tabulata, Mermessus trilobatus, Ostearius melanopygius, Hasarius adansoni, Leptorchestes berolinensis i Pseudeuophrys lanigera. Przedstawione dane uzupełniają stan poznania rozmieszczenia tych gatunków w Polsce o nowe lokalizacje oraz wskazują drogi potencjalnej ekspansji. Dla Uloborus plumipes i Hasarius adansoni wykazano istnienie dużych, rozmnażających się w Polsce, trwałych populacji.

Over the last decades, a large number of introduced spider species (Araneae) has been noted in Europe. Some of these newcomers have been introduced incidentally. However, the others develop permanent populations, for example in greenhouses or botanical gardens, and become synanthropic species. Introduction and synanthropization of new spider species also occurs in Poland. New records presented herein extend the list of introduced arachnofauna by seven species: Aphantaulax trifasciata, Cheiracanthium furculatum, Cyrtophora citricola, Olios argelasius, Nurscia albomaculata, Phoneutria boliviensis and Triaeris stenaspis. In addition, new posts of rarely reported so far in Poland synanthropic spiders such as: Amaurobius ferox, A. similis, Cheiracanthium mildei, Hasarius adansoni, Holocnemus pluchei, Nesticella mogera, Psilochorus simoni, Pseudeuophrys lanigera, Scytodes thoracica and Uloborus plumipes are presented. The data complement the deployment of these species in Poland as well as indicate their potential expansion routes.
