The information available on streblid and nycteribiid bat flies and their hosts are scant in the Araucaria Forest (AF) and there are no data on richness, distribution patterns or abundance of these ectoparasites in bat communities. Therefore, we conducted a study on bats and their ectoparasites in AF remnants (approximately 470 ha) located in the municipality of Fazenda Rio Grande, Paraná State, between December 2001 and May 2003. Twelve individuals of three species of Nycteribiidae and 119 individuals of six species of Streblidae were collected on 127 bats (four species of Phyllostomidae and seven of Vespertilionidae). Five of the six species of streblid were found exclusively on Sturnira lilium (E. Geoffroy, 1810) and Artibeus lituratus (Olfers, 1818). We collected Megistopoda proxima (Séguy, 1926) on 62 S. lilium examined with prevalence of 65.4% and mean intensity of 2.00; Aspidoptera falcata Wenzel, 1976, respectively, with 13.5% and 2.29; Trichobius phyllostomae Kessel, 1925 with 7.7% and 1.00; and Metelasmus wenzeli Graciolli & Dick, 2004 with 1.6% and 4.00. We did not find significant differences in prevalence (p = 0.544) and mean intensity (p = 0.361) between the sexes of S. lilium. On 26 A. lituratus captured we found only Paratrichobius longicrus (Miranda-Ribeiro, 1907) with prevalence of 32% and mean intensity of 1.50.
