Species level systematics is problematic. But there may be more species than the three now considered valid. There is no type specimen preserved of P. scalare, and the type locality (eastern Brazil) is imprecise.

Geographical distribution

Pterophyllum altum is known only from black and clear water tributaries of the upper Rio Negro and upper Rio Orinoco in Colombia, Venezuela and Brazil. Pterophyllum leopoldi has been collected in only a few localities along the middle Amazon River and in the upper Essequibo drainage. Several Pterophyllum species confused under the name of P. scalare are known from the Amazon drainag lowland floodplain in Colombia, Brazil and Peru, and also from the Oyapock (French Guiana) and Essequibo (Guyana) drainages.
