Abstract

An inventory of arachnids was conducted in three tropical greenhouses of Rotterdam Zoo, the Netherlands. This was part of a survey in which pitfall traps, banana baits, litter samples, hand searching and beating were used to map arthropod diversity. A total of twenty spider species, one mite taxon and one pseudoscorpion species were collected. Fourteen specimens were used for COI-barcoding, which yielded two of the listed species. Four spider species were recorded for the first time for the Netherlands: Belisana ambengan Huber, 2005, Heteroonops spinimanus (Simon, 1892), Nesticella mogera (Yaginuma, 1972) and Triaeris stenaspis Simon, 1891, the first of which is also a new record for Europe and appears to be an extremely rare pholcid species. From the species found, thirteen are nonnative to the Netherlands and four of these are considered as expansive, since they have outdoor populations as well. Hand searching yielded the highest number of species, compared to the other four sampling techniques. A species saturation curve shows that in all likelihood not all species present in the surveyed greenhouses have been found during this survey.
