confirmed as a species from Argentina:
Apistogramma trifasciata (Eigenmann & Kennedy, 1903)
remarks: López, Miquelarena & Ponte Gómez (2005) list
Apistogramma trifasciata from the río Paraná basin in the provinces of Misiones and Corrientes, and the Uruguay and Riachuelo basins in Corrientes. López et al. (2003) consider
A. trifasciata not from Argentina but ‘especie limítrofe’, meaning ‘species from neighbouring countries. Earlier López et al. (1987) had stated that
A. trifasciatum was ‘probablemente limítrofe’. Due to the southern locality for a species of
Apistogramma possibly the record of
A. trifasciata by Bonetto et al. (1970) from the laguna Tacuaral, some 70 km N of the city of Santa Fé, was not taken seriously.
As a matter of fact the presence of this species in freshwater of Argentina is well known to aquarium hobbyists, e.g. Staeck (1999) from a pond 30 km N San Roque in Corrientes and Puentes from
río Pilcomayo in Formosa.
Recently
A. trifasciata was listed by Kullander (2003) for Argentina, Brazil and Paraguay.
