I think I might have found a colony of T. tsushimae here in central MA, and I'm wondering if they've been recorded here before?
Most of them are smaller than pavement ants (about 2 mm) but there's more variation in size, with the bigger workers just as large or larger than T. caespitum.
What made me suspect that they weren't just normal pavement ants is the color variation- to a varying degree, some of the workers are paler and more reddish than their counterparts. In person, they really stand out and look like a different species of ant than their counterparts.

Same here, I was at this park and saw what appeared to be a pale reddish coloured tetramorium? I was walking a path near a park looking for queens and happened to find a Tetramorium war. I believe they were new because there was only 2 reddish tetras and 5 black tetramoriums fighting. The ones in your picture look exactly like the ones I saw.

Size can vary depending on what the colony is eating and how large the colony is. Color also varies with ants in a slight amount. This might be Tetramorium tsushimae but it could also be Tetramorium sp. e
