Results from recent research using genetic MtDNA analysis indicate Australian bass and estuary perch do belong in a separate genus to golden perch and Macquarie perch, and this may result in them being put back into a resurrected "Percalates" genus.
Results from recent research using genetic MtDNA analysis indicate Australian Bass and Estuary Perch are not congeneric with Golden Perch and Macquarie Perch. This may result in them being put back into a resurrected "Percalates" genus genetically closer to the "Maccullochella" genus (i.e. Murray cod and other cod species) than the remnant "Macquaria" genus.
