Probably U. pulchelloides but, if I'm honest, I can't really see the diagnostic red spot on the hind edge near the tip of the forewing. Antenna has small spines suggesting a male but they seem quite fine. Have you another photo by any chance?
To my eye, the row of red spots along the inner margin match the Butterfly House photo of pulchelloides much better than the one of lorix, although as you say one can't see what is at the tornus (and the spots inside the termen don't match either photo). Pulchelloides is the main southern species, and ACT are most likely to be that.
