Moved from Moenkhausia to Bario in 2024. Moenkhausia sanctaefilomenae (and the original Tetragonopterus sanctaefilomenae Steindachner, 1907) are now synonyms; keep as other names. Catalog of Fishes now treats Bario australis (Eigenmann 1908), once lumped with this species, as valid, so some southern "red-eye tetras" may belong to B. australis.
