In Argentina, there is one record of the nematode Trichuris dolichotis Morini, Boero & Rodriguez, 1955 (Nematoda: Trichuridae) parasitizing the mara Dolichotis patagonum (Zimmermann, 1780), which corresponds to its original description in 1955. In June 2023, at the Wildl ife Rehabilitation Center, San Juan province, a specimen of mara male D. patagonum died and the necropsy´s results are under investigation at the moment. Th e post-mortem identifi ed (n=5) female nematodes of T. dolichotis in the intestine. In the present study, we present the second record after 68 years of not reporting its presence, being the fi rst record for the province of San Juan and the second for Argentina. Th e present work contributes to the knowledge of the mammalian parasite fauna of Argentina..
