New Pachycondyla striata queens

Yesterday I was able to go into the woods and I was fortunate to collect a few Pachycondylas which I believe to be Pachycondyla striata. I collected three solitary female alates, a group of two and a group of four. This is a picture with one of the alates:

I put the group of four in a big plastic shoebox:

They quickly settled in and around a small "house" I built for them of damp cotton wool and a piece of cardboard on top.
