Any ideas?
The "golden" ant look a bit like Polyrhachis.
Both are Camponotus species, I think. Polyrhachis don't occur in South America.
Greetings, Phil
Damn you are right. Both are definetly camponotus. The fur of the second species distracted me but when u take a look at the second
picture of the ant you can see the typical bodyshape of camponotus spec.
