Introduction

The identity of this species needs to be determined through a species-level revision of the genus. It was based on a female holotype from "New Holland". Day (1999) included "Qld" in the type data but there was no indication of this by Walker (1851) or by Broomfield (1971).

Distribution

Recorded from "Australia".

Ecological Descriptors

All stages: phloem feeder.
