Not sure why they would change the species. Genus possibly.Very nice! Maybe these will be described as something different than brasiliensis?
A decade ago, it was thought there was only a single species in the braziliensus clade , braziliensus, but as DNA analysis has progressed, there was found to be significant enough differences between what were thought to be simply location variants, to be given species status, so a revision seems to be going on in the braziliensus clade.They would change it if the fish from that particular locality are distinct enough to merit their own species within the genus Geophagus, alongside brasiliensis and other species.

Definitely seems distinct enough from brasiliensis. Body shape is different than my brasiliensis.Very nice! Maybe these will be described as something different than brasiliensis?
