We examined 31 specimens of Rhinella granulosa from the semiarid Caatinga region of northeastern Brazil for the presence of gastrointestinal nematodes. We found 7 nematode taxa: Rhabdias androgyna, Raillietnema spectans, Aplectana membranosa, Oswaldocruzia sp., Physaloptera sp., Raillietnema sp., and cosmocercidae larvae. The total prevalence was 25.8% and by mean intensity of infection (± SD) was 50 ± 7.36. The prevalence in males was 10% with an intensity of 4 while in females it was 42.85% with a mean intensity of 42 ± 8.55. The juveniles presented a prevalence of 14.28% and an intensity of 4. Rhinella granulosa represents a new host for the following nematodes: Rhabdias androgyna, Raillietnema spectans, and Raillietnema sp.
