So I found a very small colony of these ants inside an old, dry fence. Very interesting choice of nest! They were nesting inside the cracks of the wood, and I couldn't see any shavings anywhere. At first, I thought these guys were tetramorium immigrans, because of their shape and size. But then I noticed that they all had red abdomens instead of black. And also t. immigrans doesn't typically nest in wood, so maybe this is a different species? Here's some pictures.

This being compared with an ordinary t. immigrans, pictured below:

Currently raising: 

Myrmica rubra (1 queen +  ~5 workers)

Lasius niger (single queen + ~90+ workers)

Lasius neoniger (3 single queen + brood)

Formica spp. (Queen [likely parasitic, needs brood])

Formica pacifica (Queen)

Also keeping a friend's tetramorium immigrans for the foreseeable future. Thanks CoffeBlock!

Could be a different species, this is just my thought on it:

There are slight colour variations between T.immigrans workers. I've seen some reddish and even orangeish T.immigrans. 

And although T.immigrans typically prefer nesting in pavements and grounds, they won't hesitate to nest in a different enviroment if the opportunity presents. They're a very adaptable species.
