Remarks. Laetacara araguaiae was identified as Laetacara sp. by Graça, Pavanelli (2007). Ottoni, Costa (2009) described the new species, L. araguaiae , from the rio Verde and rio Araguaia basins, and redescribed L. dorsigera (Heckel, 1840) from the Guaporé, Paraná-Paraguay system. It is a non-native species from the upper rio Paraná basin, and its occurrence can be associated with the aquarium trade.
