Cyphoderris monstrosa female
You can very clearly see the right Anders' organ just posterior to the wing pads. These stridulatory organs are orangey-red in life and a good, clear photo like this one will show that colour. Cyphoderris buckelli and C. strepitans don't have these organs, but all life stages and both sexes of C. monstrosa have them.
