Thank you Danilo Lüdke (lehelind) for identifying this species for us

General Species Information:
Found in the Adelaide Hills and possibly elsewhere
The name refers to the fact they suck the juices out of the new growth of Eucalyptus trees, which then wilt and brown off.
We thought these were Amorbus rhombifer, when (BradLP10) asked the question of how to differentiate the nymphs. We indicated that the antennae segment count & colour bands were diagnostic. We then asked Danilo if he was able to help. He indicated "Amorbus rhombifer has never been documented from SA. I consider such nymphs to be light-coloured variants of A. rubiginosus.
Steinbauer's comprehensive work (1995) contains distribution maps for all species and lists no known records of A. rhombifer and its synonyms from SA, nor are there any reports in ALA."
