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).
Szidat 1970 y S. bacilliformis
(Digenea, Haploporidae) en base a material tipo depositado en la Colección Helmintológica del Museo Bernardino Rivadavia, Buenos Aires, Argentina. La descripción original de ambas especies es breve, imprecisa y los datos morfométricos de cada una están referidos a un solo espécimen. El estudio detallado de cinco especímenes tipo de S. octavus, colectados en los ciegos pilóricos de Astyanax fasciatus (Cuv.), del holotipo y siete paratipos de S. bacilliformis, colectados en los ciegos pilóricos de Astyanax bipunctatus, revela que ambas son morfológicamente y morfométricamente similares; se caracterizan por tener el tegumento espinoso, la ventosa ventral de igual tamaño o ligeramente más grande o más pequeña que la ventosa oral y dos grupos de un número variable de folículos vitelínicos, en posición pre y postesticular. S. bacilliformis
es considerada especie sinónima de S. octavus
Anenterotrema liliputianum (Travassos, 1928) (Anenterotrematidae) is redescribed based on the type specimens from Molossus molossus (Pallas) and Phyllostomus elongatus (Geoffroy) from Brazil, and also on new specimens collected from the Dwarf Dog-faced Bat, Molossops temminckii (Burmeister) (Molossidae) in Argentina. In addition, we report the fi nding of Gymnoacetabulum talaveraensis (Lunaschi, 2002), Ochoterenatrema labda Caballero, 1943 (Lecithodendriidae), and Urotrema scabridum Braum, 1900 (Urotrematidae) parasitizing Vespertilionidae and Molossidae bats from Buenos Aires and Misiones provinces, and measurements, prevalence, and mean intensity for these trematodes are provided. In addition, the host spectrum and distribution for A. liliputianum and O. labda is increased, and U. scabridum is recorded for the fi rst time parasitizing bats in Argentina.
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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
