The PROFAUPAR project (1986–1987) studied insect diversity in the Atlantic rainforest through collections made at eight different sites in the state of Paraná, Brazil. Here, we review and identify the collected neuropterans, carry out a bibliographic review, and compose a list of the Neuroptera species that occur in the state. This study includes 14 new records in Paraná, including the first records of Ascalaphinae (Myrmeleontidae) and a new record of Dilaridae for Brazil. It increases by 29.2% the number of species of Neuroptera known from Paraná. Forty-seven Neuroptera species are now known to occur in the state.
