Notes

This species was not reported from SA until I collected it in the northern Mt Lofty Ranges in 2011, and subsequently in the Barossa Ranges, Adelaide Hills and on Kangaroo Island also.

The single KI specimen is unusual in having the pronotum with punctulate rather than striate sculpturing as in all other specimens seen. Nevertheless, DNA barcode sequencing (mitochondrial CO1) groups it together with specimens from NL and very close to a sample from NSW.

Occurrences in MU region are confined to the eastern edge of the Mt Lofty Ranges.

Host plant notes

Golden Wattle Acacia pycnantha is well established here as an adult host plant in the northern Mt Lofty Ranges, but the single occurrences elsewhere involving two other plant species may be incidental.
