A new nematode species, Trichostrongylus duretteae n. sp., found in the small intestine of C. talarum from Argentina is described. The new species more closely resembles T. suis Iwanitsky, 1930 a parasite of Sus scrofa in USSR. However the new specie can be distinguished by having rays 6 distant from rays 8 and a larger dorsal ray in relation to the length of rays 2 to 8. The present finding is the first record of the genus Trichostrongylus in rodents of the family Octodontidae.
