Comments: Cosmocerca , Aplectana , and Raillietnema are genera of Cosmocercidae which are widely distributed in several anuran species, and their females present similar morphology. Therefore, a precise morphologic identification in samples with only Cosmocercidae females is very difficult. Nevertheless, these nematodes are the first parasites recorded for P. centralis and P. mystacalis , and the second for E. bicolor since Graça et al. (2017) reported only O. oxyascaris for this microhylid.
