Abstract Helminthiasis occurs frequently in wild or domestic pigs in the most varied environments or production systems; however, the literature includes few taxonomic studies for the purpose of expanding this knowledge about the parasitic diversity in these animals. Thus, in order to expand this knowledge regarding parasitic diversity in these animals, the present study reports the occurrence and redescribes Globocephalus urosubulatus infecting domestic pigs in the state of Pará, Brazil, using microscopy. Four hundred and ten specimens of Sus scrofa intestinal nematodes were collected extensively in the municipality of Moju, northeastern mesoregion of Pará and observed under light and scanning electron microscopy. Based on morphological characteristics, the nematodes were identified as G. urosubulatus, and new morphological data were added by light microscopy and scanning electron microscopy for the diagnosis of this parasite.
