Longhorn beetle

Nice finding and spotting Sergio

Might be a case of inter-beetle mimicry. Pattern, and posture, remind of certain Straight-snouted weevils (Brentidae). Those are extremely hard-shelled, and I guess, insect-feeding birds quickly learn it's useless to attack them. Morover, males have mighty fighting jaws:

I have already seen a SE-Asian Longhorn, in which the model-mimic relation was more evident.
Hope such thoughts please you, not only IDs . . . :-)

Beautiful beetle. Beautiful picture.
