Helminth parasites of birds have been studied in Argentina for almost one century. Survey work on this group of parasites is far from complete. Here we present a checklist that summarizes the diversity of digeneans of birds from Argentina, each account is based on a literature search and gives, for each digenean species, their hosts, site of infection, localities, life cycle if known, and collection number of types where they are housed. Moreover, it presents a list of bird hosts with their digenean parasites and a list of intermediate hosts. To date, 95 digenean species have been reported; of which 27 species (29%) were new to science. These reports include 2 species of Brachylaimoidea, 2 Clinostomoidea, 5 Cyclocoeloidea, 3 Dicrocoelioidea, 21 Diplostomoidea, 26 Echinostomatoidea, 1 Gymnophalloidea, 10 Microphalloidea, 12 Opisthorchioidea, 1 Paramphistomoidea, 8 Pronocephaloidea, 2 Schistosomatoidea and 1 Troglotrematoidea. A total of 60 wild and domestic species of birds have been reported as natural hosts of digeneans in Argentina and 5 species as experimental hosts.

A summary of the literature on the digeneans of wild mammals in Argentina is presented. This is the first compilation of 51 parasitological papers published from 1909 to present. This review includes 26 native species and two introduced species (1 Artiodactyla, 6 Carnivora, 6 Cetacea, 3 Chiroptera, 2 Didelphimorphia, 1 Primate, 8 Rodentia and 1 Lagomorpha) and contains 42 species of adult digeneans belonging to 32 genera and 18 families, of which 9 species (21%) were recorded as new species. The present review provides data on hosts, geographical distribution, site of infection, life cycle, the location of material deposited in Helminthological Collections and references for the parasite species arranged by families. A host/parasite list is also provided. In addition, Gymnoacetabulum n g. is proposed to replaced the genus Suttonia Lunaschi, 2002 (Lecithodendriidae) from bats, which is preoccupied by Suttonia Smith, 1953 (Perciformes, Serranidae).

Thirteen specimens of Phalacrocorax brasilianus (Gmelin, 1789) from three areas of the Chaqueña Subregion of Argentina were examined for digeneans. Ten species were found: four diplostomids (Austrodiplostomum mordax, A. ostrowskiae, Tylodelphys adulta and Hysteromorpha triloba), three echinostomatids (Drepanocephalus spathans, Paryphostomum segregatum, and P. parvicephalum), one strigeid (Strigea falconis brasiliana), one psilostomid (Ribeiroia ondatrae) and one prosthogonimid (Prosthogonimus ovatus). Tylodelphys adulta and S. f. brasiliana are reported for the first time as parasites of P. brasilianus and new geographical records are presented.

A new strigeid digenean, Strigea inflecta sp. nov., is described from the small intestine of the Red-legged Seriema, Cariama cristata (L.) (Gruiformes, Cariamidae) from Formosa Province, Argentina. This species is characterized by having a body plump, a cup-shaped forebody with a large opening, a sacciform hindbody, without a neck region and strongly curved dorsally, a poorly delimited copulatory bursa, wider than longer, a shallow and asymmetrical genital atrium, and a genital cone well delimited from body parenchyma, strongly muscular, inclined towards the surface ventral of the body. Another digenean species collected from Red-legged Seriema, Brachylaima yupanquii Freitas, Kohn et Ibáñez, 1967 (Brachylaimidae) is described with the addition of new morphological characters and morphometrical data. This species is reported for the first time in Argentina and C. cristata represents a new host record.

A summary of the literature on the digeneans of amphibians and reptiles in Argentina is presented. This is the first compilation of 32 parasitological papers published from 1940 through 2006. This review includes 49 native species (11 frogs, 1 toad, 33 snakes, 2 turtles, 1 lizard and 1 crocodilian) and contains 42 species of adult digeneans belonging to 24 genera and 14 families as well as 5 genera of larval digeneans (metacercariae). Twenty-eight digenean species have been reported from reptiles and 14 from amphibians, of which 6 species (14.3%) were recorded as new species. The present review provides data on hosts, geographical distribution, site of infection, life cycle, the location of material deposited in Helminthological Collections and references for the parasite species arranged by Superfamilies. A host/parasite list is also provided.
