Fleas are ectoparasitic insects of many terrestrial mammals and birds. To date, a limited number of parasitological studies in Turkey have focused on fleas; and therefore, distributions and host associations of many flea species have been still poorly known. In the present study, we collected a small number (n= 678, 409 females, 269 males) of fleas from some wild animals in Sivas province of Turkey. Fleas were identified as Archaeopsylla erinacei erinacei (Boucheé 1835), Ctenocephalides canis (Curtis 1826), Leptopsylla (Leptopsylla) taschenbergi taschenbergi (Wagner 1898), Nosopsyllus (Nosopsyllus) fasciatus (Bosc 1800), Chaetopsylla (Arctopsylla) hyaenae (Kolenati 1846), Chaetopsylla (Chaetopsylla) trichosa Kohaut 1903 and Ischnopsyllus (Ischnopsyllus) simplex Rothschild 1906. Of them, C. (A.) hyaenae and I. (I.) simplex were reported for the first time in Turkey. In the present study, we also reported some new flea-host associations for Turkey.
