Cosmocerca brasiliense had the greatest prevalence (162 of 682 anurans, 24%; mean intensity = 1.8); Aplectana hylambatis had the greatest mean intensity (13.4; prevalence, 33 of 682 anurans, 5%). No host species harbored more than 7 helminth species (larval forms included); 2.8 ± 1.6 helminth species/host species.
