A total of 138 nematodes were found in the small intestine of 24 out of 42 specimens of Ctenomys talarum (Octodontidae) from Mar de Cobo (37º 58’ S, 57º 34’ W), Argentina (prevalence: 57.1, mean intensity: 7.8). A new nematode species, Pudica ctenomydis n. sp. is described. The new species more closely resembles P. pujoli Durette-Desset, 1990, parasite of Microcavia niata Thomas, from Bolivia. It can be distinguished from P. pujoli by the number of ridges of the synlophe, the spicular morphology, differences in length between ray 9 and 10, and by the presence a symetrical caudal bursa and a cuticular expansion surrounding body between vulva and anus in females.
