Genarchella  genarchella  (Travassos, Artigas & Pereira  , 1928)

Halipegus genarchella Travassos  , Artigas & Pereira  , 1928

Genarchella dubia Travassos  , Artigas & Pereira  , 1928

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).
