I'll have to correct this i.d.
It is a Patania - balteata. (as Syllepte balteata in my PhD)
It has been reared from Rhus before, which is why I was not so sure about the id......
apologies, but at least now I'm more confident of the id.
reasoning: the postmedial fascia on the forewing starts at the costa, crossing the costal stripe, in punctimarginalis; in balteata the p-m fascia starts below the subcostal vein, not at the costa.
