This is a fine professional shot.
No problem here.

Male Baoris oceia.


Baoris is easily confused with Caltoris.
The FW is longer & more imposing, especially in the male ( ie. extending out more from the HW.).
The antennal shaft is mostly black, the pale area seen in some Caltoris is absent or obscure.
The HW often have a vague pale area around the cellend.
The abdomen is obscurely banded.


Caltoris cormasa male for comparison.

Baoris farri :Browner, lighter. More often with a full complement of spots.
Male FW less sinuous , the lower half margin straighter, less excavate.
B. oceia does not occur in China or India, so examples of B. farri from there are more reliable.
