1. Location (on a map) of collection: Ambler, Pennsylvania
2. Date of collection: May 19, 2019
3. Habitat of collection: Residential complex with forested area
4. Length (from head to gaster): ~3.3 mm
5. Color, hue, pattern and texture: Dark orange/red head and thorax, shiny, iridescent black gaster
6. Distinguishing characteristics: Closely resembles Temnothorax curvispinosus, although gaster is significantly less bulbous and from ahwta I can tell, is pure black.
7. Distinguishing behavior: Tolerated, but refused to interact with T. curvispinosus. Rather timid and skittish around other ants (Camponotus pennsylvanicus, Camponotus nearcticus, T. curvispinosus), but interested in droplet of honey nonetheless.
8. Nest description:

9. Nuptial flight time and date:

 

The few photographs I managed to capture were acceptable at best and only one is informative. I hope my description will suffice.

I'm fairly confident that she is Temnothorax schaumii.

 

Her head shapetiny propodeal spines, and 11 segmented antenna all seem to align with them.

I initially considered Formicoxenus, but this does seem accurate. Mr. Trager seems to agree.

Cardiocondyla have a different petiole configuration and are much smaller than 3mm. T. schaumii is an exception as they're rather elongated for Temnothorax and are superficially similar to Leptothorax.

can temnothorax schaumii be darker, like a brownish black? if so, I have a colony.

They can be, but T. schaumii is an eastern species. Not found in California.

Cardiocondyla mauritanica is about 3mm, so you probably have that, ponerinecat

Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

This worker looks like Xenomyrmex to me though.
