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 Corrientes province was the host most frequently parasitized. Cladorchis pyriformis is recorded for the first time in H. chacarius.

Thirty families of trematodes have been reported from Rodentia (Feliú et al 2006; Fernandes et al 2015)
Summary
Digeneans are common parasites of small mammals worldwide. Around 225 species of mammals are parasitized by trematodes in South America. Thirty families of trematodes have been reported from Rodentia (Feliú et al 2006; Fernandes et al 2015). Seven species of digeneans were reported from Cricetidae in Argentina (Lunaschi and Drago 2007). Nearby 50 surveys on digeneans from mammals have been published from wild mammals in Argentina. 28 mammals species (7%) grouped into 15 families have been reported to be parasitized by Digenea (Lunaschi and Drago 2007). Only one species of Muridae, Rattus norvegicus (Berkenhout, 1769)
