This is the first report of the digenetic trematode Paratanaisia bragai infestation in a ruddy ground dove Columbina talpacoti, captured in a suburban area of Rio de Janeiro, Brazil. Although with a low prevalence (10%), the intensity of infection was high, considering that 116 worms were recovered from one of the kidneys. Gross lesions were not observed and histopathological analysis showed very dilated renal collecting ducts with destruction and flattening of the lining epithelial cells, without inflammatory reaction. The pathological findings were compared to those previously reported for P. bragai in other hosts, since the proposal of the species in 1934. O trematódeo digenético Paratanaisia bragai é referido pela primeira vez parasitando a rolinha-caldo-de-feijão, Columbina talpacoti, proveniente de área suburbana do Rio de Janeiro, Brasil. Embora com baixa prevalência (10%), a intensidade de infecção foi alta, considerando que 116 exemplares do parasito foram obtidos de um dos rins. Não foram observadas lesões macroscópicas. A análise histopatológica demonstrou grande dilatação dos dutos coletores renais, com destruição e achatamento das células epiteliais de revestimento, sem reação inflamatória. Os achados patológicos foram comparados aos anteriormente relatados para P. bragai em outros hospedeiros, desde a proposição da espécie em 1934
