The Leopard Wirrah differs from  the Western Wirrah, Acanthistius serratus, which also occurs in Western Australia, in having fewer vertical scale rows above the lateral line (99-105 vs. 110-137 in A. serratus), and stronger serrations on the scales producing a coarser feel than that of A. serratus.

Etymology

The specific name pardalotus is from the Greek word meaning 'spotted like a leopard' in reference to the characteristic colour pattern of this species.
