## Summary

The Australian cockroach (Validiblatta australasiae), synonym Periplaneta australasiae, is a species of cockroach in the family Blattidae. It is a common species of tropical cockroach, with a length of 23–35 mm (0.91–1.38 in).
It is brown overall, with the tegmina having a conspicuous lateral pale stripe or margin, and the pronotum (head shield) with a sharply contrasting pale or yellow margin.
