tiny ant - Temnothorax

tiny ant - Temnothorax
Boxborough, Middlesex County, Massachusetts, USA
March 25, 2006
Size: 2.8mm
Found a small colony of these very small ants under bark, a foot away from a queen carpenter ant.

Temnothorax sp. (Myrmicinae) - worker
Nesting place (under bark) and overall habitus leave hardly any doubt. There are quite a lot of species of these small Myrmicine ants. Most of them are extensively reddish or brownish yellow (but a few, like this one, are dark). They were formerly included in the genus Leptothorax.
Could remind of Tetramorium caespitum, but shinier, more slenderly built (postpetiolus is much narrower) and with a smaller head.
