I saw this ant-like insect in Brazil, close to Rio de Janeiro. It was around 2 cm long. I tried to use google's search by image, but no luck. Does any one know the name of the species?

Ant with a amber colored spot on it

  • $\begingroup$ I would have though a Polyrhachis is you had found it in Australia but they don't seem to exist in Brazil. Here is the list of ant species living in Brazil. $\endgroup$

  • $\begingroup$ Possibly Mutillidae or a related family? (but beyond that I have no clue). $\endgroup$

Insects like this are commonly called "velvet ants", but they are wasps, not ants. This insect is in the family Mutillidae, and it's called Hopolocrates cephalotes. (https://www.inaturalist.org/taxa/629302-Hoplocrates-cephalotes/browse_photos)
