Redescription of Trichuris pampeana (Nematoda: Trichuridae) from the south American subterranean rodent Ctenomys talarum Thomas, 1898 (Rodentia: Octodontidae)

Trichuris pampeana Suriano and Navone, 1994 (Nematoda: Trichuridae) is redescribed from voucher specimen,,; from the type host Ctenomys azarae Thomas, 1903 (Rodentia: Octodontidae) 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 a revision of these nematodes, it was confirmed that the following characters were not considered in the original description: bacillary hand, cells from the esophagointestinal junction, ejaculatory duct, vas deferens, adanal papillae, vagina, oviduct, and rectum. Additional information about the Spicular sheath, vulva, uteri, and ovary is provided. The morphological features given in this redescription allow to confirm the identify of T pampeana as a valid species Laid also to distinguish it more clearly from other species of the genus.
