Helminths of the horned leaf frog, Proceratophrys appendiculata, from southeastern Brazil

The helminth fauna of the horned leaf frog, Proceratophrys appendiculata (A nura: Leptodactylidae), was studied from 17 adult individuals from an islan d in Rio de Janeiro state, southeastern Brazil. A total of five nematode sp ecies (Aplectana delirae, Cosmocerca brasiliense, Schulzia travassosi, Rhab dias androgyna and Physaloptera sp.) and an unidentified cestode were recov ered from the digestive tract, lungs and gall bladder of P. appendiculata a nd all the nematode species are new host records. Aplectana delirae had the highest values for the prevalence and intensity of infection and can thus be considered a core species in the helminth community of P. appendiculata. Aplectana crossodactyli Baker, 1980 is synonymized with Aplectana delirae (Fabio, 1971). The helminth fauna of P. appendiculata presents characterist ics typical of those in amphibians.
