Likely leucrocuta
I am leaning toward Leucrocuta the tergite pattern and black line dividing the the head in two sections breaking apart the clypeus and the vertex crossing the lateral ocelli, that is not found on Stenacron, and the rear femora are very short Stenacron have very long rear femora and there is no hindwing shading as in Stenacron.
