During necropsy of a specimen of Lagothrix cana (É. Geoffroy, 1812) (Primates: Atelidae) from the Brazilian Amazon, pinworms were found in the large intestine. The intensity of infection was 64 parasites (17 males and 47 females) and there were no gross pathological changes related to parasitism. After morphological analysis the parasites were identified asTrypanoxyuris (Paraoxyuronema)lagothricis (Buckley, 1931Buckley JC. On two new species of Enterobius from the monkey Lagothrix humboldtii. J Helminthol 1931; 9(3): 133-140. http://dx.doi.org/10.1017/S0022149X00030364

) (Nematoda: Oxyuridae). This is the first record of this oxyurid species in primates in Brazil.
