[Brazil -Sao Paulo] 2 Queens

[Johnfer]

Hello everyone,

I need help to identify two queens. Both were caught recently. One of them already removed her wings.
The first one is small, with the size of a few mm, about 5-6 mm.

The second one is bigger, about 1,5 cm. She was still with a drone. She is beautiful (IMO ). What I found interesting is that her antennae and mandibles are very small.

Queen 2

Thanks in advance! And sorry for the bad macro, I need better lenses.

Update: both queens have laid eggs. However, I still don't know which species they belong.

Some pictures below. The smaller queen is attending her eggs, but the bigger is just ignoring them.
She stays at the cotton trying to escape. Is there a possibility that she is semi-claustral?

Thanks

[Alexander]
