The shape of pronotum with side humps, the tips of elytra and colour of antennae and legs are completely different from those in Diasporidion duplicatum.

Of course, I have seen this before, my mistake.

It is Stizocera poeyi (Guerin-Meneville, 1838). [Elaphidiini] Both this species and Diasporidion duplicatum are rather common.
