Gorgoderina cedroi Travassos, 1924

Hosts (prevalence; range): L. chaquensis (1/143; 2).

Site of infection: urinary bladder.

Stage: adult.

Type host and type locality: H. nasus (= E. nasus), Brazil.

Comments: the genus Gorgoderina present 53 known species distributed around the world, and 13 are recorded

in South American anurans (Mata-Lopéz et al. 2005; Kohn & Fernandes 2014). Probably, Gorgoderina spp. use aquatic invertebrates such as dragonfly (Odonata) or tadpoles as intermediate hosts which ingest free-living cercaria; when tadpole became adult the mature worms leave kidneys and reach urinary bladder (Bolek et al. 2009). Besides the generic characteristics, our specimens presented the main features of Gorgoderina cedroi which differs from the other species mainly by two compact and unlobed vitellines that are positioned just below to acetabulum in the ovary zone (Fernandes 1958; Mata-Lopéz et al. 2005). Leptodactylus chaquensis constitute a new host for G. cedroi since this parasite was known only for H. nasus in type locality.
