ABSTRACT
During a survey of birds from Argentina, two species of Digenea, one of them new, were found parasitizing the great antshrike, Taraba major (Vieillot) (Aves Thamnophilidae). The strigeid, Strigea orbiculata sp. n. is characterized by having a body plump, a copulatory bursa without a membraneous fold ('Ringnapf'), entire testes, eggs with miracidia with eye-spots, by the arrangement of vitelline follicles in the forebody, which are densely distributed from its anterior edge, and by the absence of a neck region in the hindbody. Among the known Neotropical species of Strigea Abildgaard, 1790, only five share with Strigea orbiculata sp. n. the body shape and the distribution ofvitelline follicles in the forebody Strigea caluri Dubois, 1962, S. elliptica (Brandes, 1888), S. inflecta Lunaschi et Drago, 2012, S. nugax Szidat, 1928 and S. sphaerocephala (Westrumb, 1823 nec Brandes 1888). However, S. caluri can be easily distinguished by having a membraneous fold in the copulatory bursa originated from 'Ringnapf', and multilobed testes. Strigea elliptica differs mainly by having a well developed 'Ringnapf' and the remaining species differ principally by metrical characters. The dicrocoeliid, Lyperosomum oswaldoi (Travassos, 1919) is reported for the first time from Argentina and T. major represents its new definitive host. The host specificity ofNeotropical Strigea spp. is discussed and an updated list of records of their hosts is provided.
