Philornis Meinert is a very interesting Muscidae (Diptera) genus whose larvae are associated with a wide range of bird species. The existing description of Philornis seguyi Garcia (1952), which was reported in Argentina, so far involves only the female. During the 2000-2002 breeding seasons, we collected Philornis flies from six bird species in Buenos Aires province, Argentina. All the flies were identified as P. seguyi. Based on this material, we describe the larva, puparium, adult male, and male and female terminalia. All the host associations presented here – Mimus saturninus (Mimidae), Troglodytes aedon (Troglodytidae), Pitangus sulfuratus (Tyrannidae), Pyrocephalus rubinus (Tyrannidae), Satrapa icterophrys (Tyrannidae) and Molothrus bonariensis (Icteridae) in nests of M. saturninus and Troglodytes aedon – are new for P. seguyi. We also present some data on the biology of the species.
