Catadiscus marinholutzi Freitas & Lent, 1939

Hosts (prevalence; range): L. fuscus (1/50; 1), L. podicipinus (45/225; 1–7), T. typhonius (2/16; 2–3) and P. azureus (1/47; 5).

Site of infection: small and large intestines.

Stage: adult.

Type host and type locality: L. latrans, Camis „o, Mato Grosso do Sul State, Brazil .

Comments: the genus Catadiscus is endemic to the Neotropical region and commonly found in the large intestine of anurans ( Jones et al. 2005). The species from this genus are characterized by a large and terminal acetabulum, short caeca that do not reach acetabular zone and a single testis ( Freitas & Lent 1939). Catadiscus marinholutzi resembles Catadiscus propinquus Freitas & Dobin Jr. and Catadiscus uruguayensis Freitas & Lent. However , from the morphological analysis of the small oral sucker, rounded testis, globular cirrus sac, pharynx length, and size and amount of eggs we concluded that our specimens belong to C. marinholutzi (see Freitas & Lent 1939). Leptodactylus fuscus , T. typhonius , and P. azureus constitute new hosts for C. marinholutzi .
