Paropsis rufitarsis
Paropsis rufitarsis (Chapuis) It was found on a black Wattle tree (Acacia aulacocarpa) but feeding on acacia is unlikely
This clumsy green beetle has been seen in Gin Gin and again south of Cooktown.
I had thought this is Dicranosterna but Chris Reid thinks it is Paropsis, allied to obsoleta.
Thank you Gunter for the ID
