Not Stenacron, probably Leucrocuta

Size alone would make Stenacron unlikely, but notice the unmarked legs and that the darkest grouping of crossveins is in-between R1 and SC (Stenacron would have them between R1 and R2). Compare this specimen to the one on the Leucrocuta page--they are probably the same species.
