Contribution to the Croatian spider (Araneae) fauna: new records and rarely documented species from intermittent rivers

We surveyed ground-dwelling spiders using pitfall traps in four intermittent rivers in Croatia. Among 159 species recorded, 15 species of faunistic interest are presented here, comprising new records for Croatia, new records previously reported in grey literature or in online databases, and rediscoveries of species previously reported in scientific literature. Our records extend the known European ranges of several species, including the recently described Turkozelotes noname Mazzia & Cornic, 2020 and Mesiotelus confusus Zamani, Fomichev, Naumova & Marusik, 2024. Our findings indicate that the Croatian spider fauna remains incompletely known and highlight the value of repeated pitfall trapping for documenting ground-dwelling spiders.
