Detail of ventral surface. Elongated scent gland channel (arrows), extending more than half-way to edge of metapleuron , differentiates this from Nezara, which has a shorter, more rounded scent gland channel. (The metapleuron is the rearmost plate on the underside of the thorax, I think.) See Slater, p. 50, figs. 70, 72 (1).

This shot is interesting because you can see the fluid in the channel. After the photo session, I discovered that my fingers had been stained brown in places by this fluid. The defensive fluid is supposed to contain quinones (2).
