Taxonomic Remarks
P. vittata is a very small species. The type is an aquarium specimen said to be from Óbidos on the lower Amazon River and not far away C. Ternetz collected a specimen near Santarém in 1925. However more recent collections have been limited to far western localities in Bolivia, Brazil and Peru. Like P. spilota it has black spots across the body. However there only three and these are larger and almost black. Eschmeyer, 1998:1770; Ortega and Vari, 1986:11.
