Material deposited: CHIOC (type material), MACN- Pa 600, 601, 602, 603 (new voucher material).

Hosts: Oligosarcus sp. (= Acestrorhamphus sp.) (type host, Brazil); O. jenynsii (Günther) , Charax stenopterus (Cope) (= Asiphonichthys stenopterus Cope ) ( Characidae : Characidae ), Salminus brasiliensis , Leporinus friderici (Bloch) ( Characidae : Anostomidae ); Iheringichthys labrosus *, Luciopimelodus pati *, Pimelodus albicans , P. maculatus (= Pimelodus clarias Linnaeus ).

Localities: Emas Pirassununga, São Paulo State, Brazil (type locality); Middle Paraná River, El Dorado, Misiones Province; Colastiné River** (tributary of Paraná River), Santa Fe Province; Paraná-Guazú River**, Entre Ríos Province; Lujan River (Luján), Los Talas (Berisso), and Chascomús Lagoon (Chascomus), Buenos Aires Province.

Site of infection: Esophagus, stomach, intestine.

Life cycle: IH1 and IH2 Heleobia australis (d’Orbigny) (see Szidat, 1956); H. parchappii (see Martorelli, 1989).

References: Szidat (1956a), Martorelli (1989), Kohn et al. (1990), Arredondo (2013).

Remarks: New hosts and locality records. Szidat (1956a) mentioned H. australis as intermediate host, but this is a misidentification (see Martorelli, 1989). The progenetic metacercaria produces viable eggs, which are infective for the snail. The life cycle could be maintained without a vertebrate host for several years ( Martorelli, 1989).
