Abstract: This work contributes to the knowledge of digeneans in two species of Holochilus Brant, 1835 from nine localities of Argentina. Morphological characteristics and ecological data are provided. Holochilus vulpinus (Brants, 1827) and H. chacarius Thomas, 1906 were parasitized by only one digenean species, Cladorchis pyriformis (Diesing, 1838). The morphometric features of this species and those reported by previous authors from South America are presented and compared. Holochilus vulpinus and a locality of Corri… Show more

Notocotylidae is a family with a cosmopolitan distribution, with 13 genera parasitizing birds and mammals. Four of these genera were registered in the Americas, and two parasitizing rodents in Argentina. In this paper, specimens of the genus Hippocrepis parasitizing Holochilus brasiliensis from Argentina are studied on the basis of morphological and molecular characteristics. Eleven Ho. brasiliensis specimens were collected in seven localities from the Cuenca del Plata region. A total of 192 specimens of digeneans were found in a single Ho. brasiliensis. Conventional morphological and molecular analyses were used. The digenean specimens were identified as Hippocrepis fuelleborni. Furthermore, the molecular characterization of three genetic markers for Hi. fuelleborni is provided. This study contributes to the first record of the genus Hippocrepis in cricetid rodents. The continuity of the studies on this genus and the incorporation of more haplotypes from different genera of Notocotylidae will allow us to recognize the relationship among genera and provide a new systematic proposal.

Digeneans are common parasites of small mammals. Dicrocoeliidae is a family with a cosmopolitan distribution, with 18 genera previously recorded from mammals in the Americas, six of them parasitizing rodents in Argentina. In this study, an updated compilation is provided of Dicrocoeliidae from rodents in the Americas. Also, a new Platynosomoides species is described parasitizing the cricetid rodent Akodon montensis of the Atlantic Forest in Argentina. Digital repositories were used to search for Dicrocoeliidae from rodents in the Americas. Rodents were collected in four localities of the Atlantic Forest, Argentina. Digeneans were removed from the rodent's bile duct, and conventional studies were used for the morphological description. A total of 15 Dicrocoeliidae species were found parasitizing 18 rodent species from eight countries in the Americas. The new species of Platynosomoides from Akodon montensis differs from the other two species of genus by the size of body, testes, ovary, cecum length and position and length of the vitelline bands. Dicrocoeliidae show growing diversity, and the compilation of species in a rodent host base allows a clearer comparison and identification of new taxa in the future.

Introduction Among Argentinean rodents, only one species of Muridae and seven of Cricetidae were reported as digenean hosts. Despite the available data, the taxonomic diversity of the Digenea from rodents has been little explored. An update on digeneans of Sigmodontinae rodents (Cricetidae-Muroidea) in Cuenca del Plata is provided. New host and geographical data are recorded and taxonomic and ecological data are summarized. Methods Rodents were collected from 11 localities in the region Cuenca del Plata, Argentina. Moreover, other unidentified specimens from four localities, deposited in the Colección de Helmintología del Museo de La Plata, were studied. Prevalence, mean intensity, and mean abundance are provided. Results Eight species of digeneans belonging to four families were identified. Twelve new geographical records for five provinces of Argentina are presented. In addition, six new host-parasite associations are reported. The information is presented in a taxonomic list for each digenean species: site of infection, host records, locality records, and comments. Conclusions It becomes interesting to explore the diets and habits of each rodent species to understand the dispersal and transmission ability of each group of digeneans. This survey constitutes an update on digeneans of Sigmodontinae rodents in Cuenca del Plata, Argentina.
