Acanthocephalans are grouped in a single phylum, having a cosmopolitan distribution and subdivided into three classes. Although species of this parasite acanthocephalans of the genus Centrorhynchus have birds and mammals as definitive hosts, they have been reported in amphibians and reptiles, and have been noted as paratenic hosts. In this study we report the record of Rhinella major as a new paratenic host for the Centrorhynchus sp. from an urban area of the Brazilian Amazon. In this study, for the morphometric measurements to take place, the parasitic specimens found were fixed in an alcoholic liquid medium and the identification of the parasites found were confirmed by specialized literature. The parasitological statistical parameters followed the proposed ecological concepts, calculating the parasite prevalence, intensity, average intensity and average abundance indices with confidence intervals. In the present study, two morphotypes of Acanthocephala were found parasitizing R. major. In this study we report the record of R. major as a new paratenic host for the Centrorhynchus sp.
