Streblidae and Nycteribiidae are exclusively found in association with bats. The main objective of the present work was to investigate the diversity of bat flies found in bats from the Perobas Biological Reserve, state of Paraná, Brazil. The work was performed in the months of May, June and August, 2008 and February, March and April, 2009. For the capture of bats, 32 mist nets were used, totalizing a capture effort of 43,520 m²h. Ectoparasite capture was made manually or through the aid of a forceps. Specimens were conserved in 70% alcohol and identified with the aid of a stereoscopic microscope. Data was analyzed by means of a non parametric Bootstrap and descriptive statistics. Bat flies species identified were: Aspidoptera falcata Wenzel, 1976, Megistopoda proxima (Séguy, 1926), Megistopoda aranea (Coquillett, 1899), Paratrichobius longicrus (Miranda Ribeiro, 1907), Trichobius tiptoni Wenzel, 1976 and Basilia quadrosae Graciolli & Moura, 2005. Estimated richness curve indicates tendency to the occurrence of other ectoparasitic species in the conservational unit, since a horizontal asymptote was not achieved. The data obtained is corroborated by the respective data in other Brazilian regions and contribute with information about the group diversity in the Atlantic Forest Biome from the northwest of Paraná.
