Notes

The fish looks similar to the Giant Squirrelfish, Ostichthys japonicus, but can be distinguished by the shape of the premaxillary groove (the deep U-shaped slot that is visible in the image between the upper jaw and the eyes) which is long, with roughly parallel sides compared with the wide, triangular premaxillary groove of the Giant Squirrelfish.

The species is known from off south-western Western Australia and New South Wales.
