Prosthenorchis elegans is an acanthocephalan intestinal parasite reported in neotropical primates. Despite parasitism by P. elegans having already been described in wild marmosets in the Brazilian Atlantic Forest, there are no reports of this infection in wild Geoffroy's marmoset (Callithrix geofroyi). The aim of this study is to report one case of P. elegans parasitism in a free-ranging C. geoffroyi from Brazilian Atlantic Forest in Espirito Santo state, and characterize the pathological and parasitological findings of this infection. One Geoffroy's marmoset necropsied at the Vila Velha University's Veterinary Pathology Laboratory presented intense chronic transmural ulcerative enteritis associated with twenty cylindrical helminths present in the jejunum and ileum. We can conclude that parasitism by P. elegans occurs in free-ranging groups of Geoffroy's marmosets. Its infection produced severe intestinal lesions even in free-ranging marmoset and therefore is a threat to this animal's survival in wildlife and can have some impact on primate conservation in the Brazilian Atlantic Forest.
