E-mail: Abstract: A list of spider species recorded from the Parque Estadual Mata São Francisco, Paraná, Brazil was compiled based on 7,942 specimens, of which 2,872 are adults (36.15%) and 5,071 are juveniles (63.85%). Adults were identified as belonging to 45 families, 140 genera and 209 speciesConifaber and morphospecies guarani Grismado, (101 2004nominal and species Oonops and nigromaculatus 108 morphotypes). Mello- Forty-one species were recorded for the first time from the state of Paraná, most of them belonging to Araneidae (14), Oonopidae (4), Theridiidae (4), and Uloboridae (3). Leitão, 1944 were recorded for the first time from Brazil. These results place Paraná as the sixth state with the highest knownnumber species of records in Paraná. of spiders from Brazil, currently 465 species. This study increases in 10% the number of species recorded from Paraná, and the Atlantic Forest fragment becomes one of the most well sampled areas in the state, with 20% of all DOI: 10.15560/10.6.1435 Introduction comparisons with the previous literature (Brescovit et al.
