RESUMO
Opiliones are arachnids that provide different services in terrestrial ecosystems, especially in tropical forests, which justifies inventory studies to better understand the occurrence and distribution of these arthropods in Brazil, since little is known about the harvestmen fauna in Conservation Units such as in the state of Paraná. In this context, the objective of the present study was to survey the harvestmen fauna at the Iguaçu National Park (PARNA) and in the Bela Vista Biological Refuge (BVBR), from September 2021 to May 2022, using a sampling effort of 40 hours in the BVBR, and 66 hours at the PARNA Iguaçu. Ten species/morphospecies were recorded, highlighting a new occurrence for Brazil, the species Opisthoplatus vegetus. The present study reduces the information gap about Opiliones in the state, which reaffirms the importance of Conservation Units for the protection of the biota in the state of Paraná.
