nr 1

The life cycle of Pygidiopsis australis sp. n. was reproduced experimentally, starting from cercariae from naturally infected Littoridina castellanosae (Hydrobiidae) collected from artificial ponds in the Zoological Garden in Buenos Aires. Metacercariae were found encysted in the mesenteries, internal organs and body cavity of experimentally exposed Cnesterodon decemmaculatus (Poeciliidae). Adults were obtained experimentally in chicks and mice. The adult could not be distinguished from P. pindoramensis Travassos, 1929; the cercariae are clearly different in the arrangement of penetration glands and in the absence of pigment granules in the body of P. australis sp. n.

Adult specimens of Stephanoprora uruguayense Holcman-Spector et Olagüe, 1989 were obtained experimentally by infecting chicks with cysts from the gills of Galaxias maculatus (Jenyns, 1842) from Andean Patagonian lakes. Specimens of this species were found in nature parasitising Larus dominicanus (Lichtenstein, 1823) in the same area. The species is redescribed and the validity of Stephanoprora spp. from birds of South America as well as the status of Stephanoprora manei Holcman- Spector et Olagüe, 1986 are discussed. Beaverostomum Gupta, 1963 is considered synonymous with Stephanoprora Odhner, 1902. Stephanoprora dogieli Holcman-Spector et Olagüe, 1989, S. podicipei Etchegoin et Martorelli, 1997 and S. denticulata described by Torres et al. 1983, are synonymised with S. uruguayense.

Acanthostomoides apophalliformis Szidat, 1956 is redescribed and its distribution, prevalence and mean intensity of infection in different Patagonian lakes is included. Mature adults were found mainly in the digestive tract of Percichthys trucha, rarely in Oncorhynchus mykiss and Diplomystes viedmensis (new host record). The metacercaria parasitised mainly the liver of Galaxias maculatus and G. platei. Opistorchioid cercariae emerged from Heleobia hatcheri. Experimental infections with cercana exposed to G. maculatus were successful and the immature metacercaria obtained were similar to those naturally found in the same host.
