Guerrerostrongylus zetta had been found in a number of different species of rodents from northern and southeastern Brazil as well as Argentina. Between 2008 and 2010, specimens of Oligoryzomys nigripes ( n = 14) were collected and necropsied. The nematodes encountered were identified as G . zetta due their morphological traits. Prevalence was 78%, with a mean intensity of infection of 5.63 helminths/host. This report fills in a lacuna in the known distribution of G. zetta , and provides the first record of this parasite in the state of Rio Grande do Sul, Brazil.
