Now we know!

My dear friend Enmos spent hours trying to find out the species of this longhorn beetle I posted this week.

Here’s what he wrote:

I’m pretty sure I got it down to the genus (the longhorn beetle with the green/yellow stripes/spots)
It has got to be of the genus Ambonus! :D

Images of some species from this genus:
Ambonus distinctus
Ambonus interrogationis
Ambonus lippus
Images form this website: http://www.faunaparaguay.com/cerambycinaeimages.html

These three are native to Paraguay and at least Ambonus interrogationis is also native to Argentina.

I think Ambonus distinctus comes closest to your specimen though. Perhaps yours is just a bit more distinct then the one in the picture.

I have seen hundreds and hundreds of different Longhorn Beetles and these are with significant distance the most similar.
Ok, I’m going to try to find out the species now.

And then:

Alright, I think I’m convinced that it actually is Ambonus distinctus!

I found this image of Ambonus distinctus, From website: http://www.sel.barc.usda.gov/coleoptera/elaphid/Ambonus.htm

And your image.

And it’s native to Brazil!

I guess I was right before about yours just being a bit more distinctive than the one in that other picture.
There is still a change that another species of that genus is even closer. There apparently are eight species in this genus and I’ve only been able to find these three.
I’ll see if I can find more.

Huge thanks, Enmos! Now you can sleep :D
