Trichuris pampeana Suriano and Navone, 1994 (Nematoda: Trichuridae) is redescribed from voucher specimens from the type host Ctenomys azarae (Rodentia: Octodontidae) Thomas, 1903 and from parasites collected from 2 populations of the subterranean rodent C. talarum Thomas, 1898 from Mar de Cobo and Necochea, Buenos Aires Province, Argentina. After revision of these nematodes, it was confirmed that the following characters were not considered in the original description: bacillary band, cells from the esophagointestinal junction, ejaculatory duct, vas deferens, adanal papillae, vagina, oviduct and rectum. Additional information about the spicular sheat, vulva, uteri and ovary is provided. The morphological features given in this redescription allow the confirmation of the identity of T. pampeana as a valid species and to distinguish it more clearly from other species of the genus.
