Thank you very much for an exact ID. I have edited the spotting to reflect this. It is one of the coolest beetles I've ever seen.

I'm not a specialist of this group but i try to understand more the biology of this group of beetles. Many species are new for the Science, so it's really exciting and interesting to describe them.
I began on french guyana Athyreini two years ago. And i try to collect more material from south and central america. It's a group difficult to collect, at light and with interception trap only.

Happy to help you

Ha, Tuberifer! That's one from my link... Just kidding... I also commented, that we need a real expert for this one. Boilly is obviously one! Thanks! Could you, please, give us some more information about you, since we have a lot of real experts here, so we wanna know the Who Is Who of Project Noah.
Btw: Welcome!!

It's a mâle Athyreus tuberifer Felshe, 1909
The species from Athyreini tribe are often attracted by lights.
I work on them, it's a very interesting group.

Wonderfull picture !!



Lovely!! hope you get an ID.
Maybe I will be closer to an ID to my own beetle (escarabajo) very similar to yours:

I also would tend to Athyreus.

Awestruck! My new favourite beetle :)

Awesome spotting.

I think Athyreus rather than Neoathyreus. A. bellator seems the closest match that I can find for a beetle with a Brazilian distribution. I'll ponder a little longer though.

Is he from the Wild West ? or a bucking bronco? what a fantastic-looking specimen ! and a great shot...thanks for sharing.

And it is certainly the male ;-)!

Scaraboideae, Geotrupidae, Athyreus sp. or Neoathyreus sp.. I think ID is not possible without the native specimen and/or a real expert.
Usually I do not like this sites where you can buy pinned animals, but sometimes you find something interesting.

Armored woolly mammoth rhinoceros pronghorn perhaps? Great spotting!

Fantastic. Scarambeidae, for sure, but I never saw one like this.

Bizarre and beautiful at the same time!

Wonderful picture and a very unusual scarab. It does seem to be some species of Dung Beetle.
