Les strigeata (Trematoda) de la collection A. Lutz

First record of Australapatemon burti and Paramonostomum pseudalveatum (Digenea) from Anas georgica (Aves, Anseriformes) in Chile

“…A. minor differs from the strigeids from A. georgica by the size of the body (up to 2.5 mm long), anterior testis (99-306 µm long by 70-326 µm wide), posterior testis (130-408 µm long by 99-367 µm wide) and genital cone (150-280 µm long by 120-190 µm wide). A. bdellocystis differs from the specimens here studied by the shape of testes described as not lobed by Szidat (1929) and Dubois (1968Dubois ( , 1970 and grossly lobed by . The morphological and metrical characters of specimens obtained from A. georgica are in full agreement with those of A. burti from Anas discors L., A. crecca carolinensis Gmelin, A. penelope L., A. rubripes Brewster, A. americana Gmelin and Aythya affinis (Eyton), Cygnus columbianus (Ord) and Melanitta nigra (L.) from USA and Canada described by Dubois (1968).…”

Australapatemon fuhrmanni, A. canadensis, A. anseris and A. congolensis differ from our specimens of A. burti obtained from A. georgica by having a muscular ring in the genital atrium (ringnapf).…”

Digenean parasites of Ciconiiform birds from Argentina

“…Later, it was reported parasitizing other Brazilian birds: C. atratus, Sarcoramphus papa (L.), Cathartes burrovianus urubitinga Pelzeln, (Cathartidae), Cariama cristata (L.) (Cariamidae), and Spizaetus ornatus (Daudin) (Accipitridae) (Szidat, 1929;Travassos et al, 1969). Strigea vaginata was also found parasitizing C. atratus and an indeterminate accipitrid (cited as "gavilán" and "gavião") in Venezuela (Lutz, 1928;Dubois, 1970a); Cathartes aura aura (L.) in Cuba (Dubois and Macko, 1972); Theristicus caudatus, Cercibis oxycerca (Spix) (Threskiornithidae), and Caracara plancus (Miller) (Falconidae) in Colombia (Dubois, 1978(Dubois, , 1981. According to Szidat (1929) and Dubois (1968), the specimens collected in the black vulture from Formosa Province were identified as S. vaginata mainly by the presence of an enormous copulatory bursa and genital cone, occupying almost half of the hindbody.…”

A new species of Parastrigea (Digenea, Strigeidae) endoparasite of Buteogallus urubitinga (Aves, Accipitridae) from Argentina

“…mexicana Coil, 1957 (Table 1). Moreover, a sixth species, P. robusta Szidat, 1928, was listed in Brazil parasitizing Jacana spinosa jacana (L.) by Noronha et al, (2009), although Dubois (1970) considered questionable this report for South America, given the poor condition of the specimens. In Argentina, P. brasiliana was listed parasitizing ardeid birds (Lunaschi et al, 2007), however, these specimens were transferred to Apharyngostrigea ardearum (Lutz, 1928) Dubois, 1968(Drago & Lunaschi, 2011.…”
