A survey of the louse flies species (Diptera, Hippoboscidae) in the State of Paraná, Brazil was carried out. Keys to eight genera and 15 species found are given. The following species are recorded for the first time in Paraná: Lipoptena (Lipoptenella) guimaraesi Bequaert, 1957; Stipolmetopoda legtersi Bequaert, 1955; Icosta (Ornithopomus) latifacies Bequaert, 1955; Icosta (Ornithpomus) rufiventris (Bigot, 1885); Icosta (Ardmoeca) albipennis (Say, 1823) and Olfersia bisulcata Macquart, 1847. Baryphthengus ruficapillus (Vieillot, 1818) (Momotidae) and Ciccaba virgata Carbin, 1849 (Strigidae) are new host records for Ornithoica vicina (Walker, 1849) and I. (Ardmoeca) albipennis; Chiroxiphia caudata (Shaw, 1793) and Schiffornis virescens (Lafresnaye, 1838) (Pipridae) for Ornithoctona fusciventris (Wiedemann, 1830) and Gallus gallus domesticus (Linnaeus, 1758) (Phasianidae) for S. legtersi.
