I found a migrating colony on the concrete steps of my in-laws. There were about a hundred workers with three queens. I pulled an empty chewing gum container and flicked in as many as I could. The ants are very fragile, one queen squished with a slightest touch. The ants are small 2mm, queens around 5mm. Black, but thorax red. They are acid sprayers.
Location (on a map) of collection: 
2. Date of collection: Oct 2020
3. Habitat of collection: Street, mostly concrete. Some trees alongside the road. Little soil.
4. Length (from head to gaster): 2mm workers, 5mm queens
5. Color, hue, pattern and texture: black with red thorax.
6. Distinguishing characteristics: spray acid, polygyne
7. Distinguishing behavior: careful, spray acid
8. Nest description: ?
 
9. Nuptial flight time and date: not caught during a flight bit nest branching/migration.
 
Lepisiota sp?

Honestly looks like Formica but probably not because of the size.
We don’t talk about that

Fairly sure these are Lepisiota frauenfeldi. Do the workers have unusually structured propodeums?

Definitely Lepisiota frauenfeldi. Basically paratrechina longicornis but more colorful

Not sure if anything can be seen from the photos taken by this ghastly microscope, but here it is... I cannot spot spines...hm

Workers have more distinct spines that gynes.
