This study aims to register the occurrence of Trypanoxyuris (Trypanoxyuris) minutus in Alouatta guariba clamitans, in Minas Gerais state, Brazil. Two specimens of A. guariba clamitans, died accidentally, have been necropsied for parasito-logical studies. Only the large intestine and caecum were infected by T. minutus. The parasitism intensity was 6650 parasites and the density was 2.6 parasites/cm³ of large intestine. In the caecum, the mean intensity was 6753 ± 490.73 parasites, with mean density of 6.23 ± 5.13 parasites/cm³. The present study supplies information on adult nematodes biometry and this is the first record of T. (T.) minutus in A. guariba clamitans from Minas Gerais State, Brazil.
