I don't like to be so arrogant as some clearly do, in assuming that I'm always correct, I'll take that '?' away for you then. You don't even need to look at the 'largely absent' orange spots either, the absence of a cell spot in the basal half of the forewing is enough.
Maybe change that name to 'off the Rayles' ..............
