Biggest clue is the antennae, which do not have the usual Hesperiidae apiculus or hook. That eliminates all of the lookalikes and leave you Taractrocera. I think a quick flip of C&P4 should help you nail the ID quite easily.
Flipped many times already. Just want to make sure I am correct.

If the spot is hidden or the hindwing photographed edge-on it could easily be identified as P. confucius.
