could be

but I am still unclear the difference between Dicerca and Poecilonota, as the reddish tails make me think Poecilonota cyanipes....but I could be way wrong....Can anyone point out the smoking gun for those two genera?

Poecilonota vs Dicerca

The difference (evident in this photograph) is that Poecilonota has a transverse scutellum, much wider than long, whereas Dicerca has an almost round scutellum.

Poecilonota has a single poli

Poecilonota has a single polished ridge running down the middle of the pronotum, while Dicerca has two ridges on either side of the midline. This looks like Poecilonota to me.

Agreed

The scutellum is unique as well

That small light green spot at the base of elytra look as the one following image
