It contains two species, both of which were previously placed in the
temperate perch genus
Macquaria. However, more recent phylogenetic studies have found these two species to be the most
basal members of the order
Centrarchiformes, and thus more distantly related to the temperate perches than previously thought. The following species are known: Partial fossil remains from the
Lutetian-aged marine
Kuldana Formation of Pakistan have also been assigned to this species, albeit based on an older taxonomic treatment of the
Percichthyidae. Many other fossil remains assigned to this genus are also known the
Oligocene and
Miocene of Australia, though it is uncertain whether they belong to this genus or to
Macquaria. == References ==
