On the pronotum and the scutellum, the tinting is more visible The abdomen itself is a rich ruddy-brown with green shine.

The underside of the beetles has white hairs; these are longer on the thorax and distributed everywhere except the midline and sparser and smaller on the abdomen where they are only found on the sides.
