Prior to the present study, Nematomystes scapteromi (Ganzorig, Oku, Okamoto, Malgor & Kamiya, 1999) Jiménez-Ruiz & Gardner, 2003 had been reported in Scapteromys tumidus Waterhouse, 1837 from Uruguay. Here, eight specimens of S. tumidus were collected in southern Brazil and necropsied. The nematodes encountered were determined as N. scapteromi through their morphometric traits. Prevalence was 87.5% and the mean intensity of infection of 18.3 helminths/host. This is the first report of N. scapteromi parasitizing S. tumidus in the state of Rio Grande do Sul, Brazil.
