Pterygoplichthys - Taxonomy

Taxonomy

Pterygoplichthys has undergone much shifting in the past decades. Previously Liposarcus, Glyptoperichthys and Pterygoplichthys had been named as separate genera. Since then, these genera were recognized as synonyms of Pterygoplichthys by Armbruster, as the few differences between the genera were not deemed great enough to validate Glyptoperichthys and Liposarcus, and that recognizing these separate genera would leave neither Pterygoplichthys nor Glyptoperichthys as monophyletic.
