This yellow skipper has unusual markings, especially on its lower hind wing. Unable to get an upper wing shot. What could it be?

The sinuate wingshape ,banded abdomen & colour indicate it is Baoris.

The two species can be very confusing.

Baoris farri generally lighter brown ; spots often more complete.
In India where B. oceia is absent, the two below are B. farri males.

Baoris oceia; generally darker brown ; spots more often smaller & reduced.
B. oceia males ,Singapore.

Probable ID. Baoris oceia male.
Note there is only one tiny subapical spot (spot 6) The individual is very worn & faded.
