Family ORTHEZIIDAE
Introduction
The Orthezidae is regarded as a primitive family that may have originated in the Cretaceous Africa-South America land mass and subsequently dispersed to other areas on Recent plant families (Williams 1984). The adult female secretes symmetrical wax plates on the dorsum, and a distinctive wax ovisac at the posterior end of the abdomen.
The described Australian fauna comprises three genera and eight species and includes introduced species.
