Hello! Here come some information:
Location: Juiz de Fora - Southeast region of Brazil.
Size: 2 centimeters
I captured this queen a week ago. Now she is on a small pot with some moistened cotton. She spends most of her time over the cotton, seems to like the humidity a lot.
I was looking some pictures at Google and she seems like some kind of Pachycondyla. Could be it?
Here are some pictures. Sorry but I have problems with the reflections on the test tube.
