The big heads are what tell me it’s Tetramorium.
"The ants are a people not strong, yet they prepare their meat in the summer." Prov. 30:25
Keep ordinary ants in extraordinary ways.

What characteristic makes this not an Argentine Ant colony?

This is clearly from the subfamily Myrmicinae, which are easy to distinguish due to their square, bulky builds, and especially the long petioles (bridge between thorax and gaster) with many modest (bumps). Argentines are in subfamily Dolichoderinae, which are much lankier and rounder in every aspect, and whose petioles are not nearly as noticeable.

Linepithema are long while Tetramorium tend to be rounded, actually. Myrmicinae are an extremely diverse subfamily, there are bulky, square genera and lanky, smooth genera. However, yeah the petiole is a giveaway, Dolichoderines have a "hidden" petiole, and the general body shape is pretty diagnostic of immigrans group Tetramorium.

Look up Linepithema humile and then look up Tetramorium immigrans, then you’ll see.
