title: Digenean fauna in raptors from northeastern Argentina, with the description of a new species of Strigea (Digenea: Strigeidae).
abstract: The digenean fauna of six species of falconiform birds from northeastern Argentina is reported and a new species and several new hosts and geographical records are presented. Strigea proteolytica n. sp. (Strigeidae) is described from Buteogallus urubitinga and distinguished from their congeners by the combination of the following characters: plump body, conspicuous proteolytic gland, forebody with scarce vitelline glands, copulatory bursa with a well developed muscular ring (Ringnapf), and absence of true neck region in hindbody. Six previously known species are breifly described: Strigea falconis brasiliana Szidat, 1929 (Strigeidae) from Milvago chimachima and Caracara plancus; Neodiplostomum travassosi Dubois, 1937 from Buteogallus meridionalis; Tylodelphys brevis Drago & Lunaschi, 2008 and Posthodiplostomum macrocotyle Dubois, 1937 (Diplostomidae) from Busarellus nigricollis; Spaniometra variolaris (Fuhrmann, 1904) (Cyclocoelidae) and Megalophallus deblocki Kostadinova, Vaucher & Gibson, 2006 (Microphallidae) from Rostrhamus sociabilis. Literature records and information on distribution and host-parasite relationships is presented.
