List of spider species in an urban forest fragment in the Brazilian Amazon with 16 new local records and 3 new records for Brazil
Summary
The order Araneae comprises more than 52,000 described species of spiders and, despite the high diversity, there is still much to study about the taxonomy and biogeography of the group, especially in tropical regions. In this work, we provide a list of spider species/morphospecies from the Research Campus of the Museu Paraense Emílio Goeldi, Belém, Pará, Brazil, with new records at different scales. Collections occurred sporadically between 2011–2018, using different collection methods. A total of 492 individuals from 172 morphospecies were sampled, distributed in 103 genera and 25 families. It was possible to determine 84 species (48.8%), with 16 new records for Belém, including seven for Pará and three for Brazil. The relatively high species richness can be explained by several factors, such as sampling at different times of the year, the use of various collection methods, and the fact that the study area is connected to an extensive forest matrix to the northeast, possibly allowing the dispersal of individuals between areas. Finally, the new records, the high species richness, and the number of undetermined species highlight the challenges of obtaining an acceptable level of faunal knowledge of spiders in the Amazon.
