In Argentina, parasitological studies in Cricetidae rodents have been carried out mainly on nematodes. However, some research has shown that cestodes are also common components of their parasitic assemblages. In this study, Sigmodontinae rodents (Cricetidae-Muroidea) from the Cuenca del Plata, Argentina are studied as hosts of cestodes. New host species, geographical areas and parasitic infection parameters are provided. A total of 1675 specimens from28 species of rodents from 67 localities were sampled for cestodes. Five taxa of cestodes belonging to three families were identified, including 20 new geographical records. In addition, nine new host-parasite associations are reported. These records help us to increase our understanding of richness of cestodes in the region, providing a data base to evaluate the effect of intrinsic and extrinsic factors on ecological indicators such as prevalence, abundance, and host specificity, among others.
