1. Location (on a map) of collection: Tucson, Arizona.
2. Date of collection: 8.4.2019 at night
3. Habitat of collection: Urban desert scrub habitat. Specifically, this ant was found crawling on my bed.
4. Length (from head to gaster): 13mm
5. Color, hue, pattern and texture: Very dark brown/black color. Shiny rather than matte. Has fine yellow hair covering body, but most apparent on head. Short yellow hairs on underside of head. 
6. Distinguishing characteristics: This ant has an interesting pair of jaws. The mandibles are long, slender, and pointy. They form a hollow triangle shape when closed. From a head on view, her mouth parts can be seen through the gap in her mandibles. Appear to be more effective for piercing rather than crushing or chewing. She also has two petiole nodes, and her head is wider than it is tall.

7. Distinguishing behavior: This ant does not appear to be a good climber on smooth surfaces. She has significant trouble finding footing in her tube setup.
8. Nest description: —

9. Nuptial flight time and date: —

Thanks! Was wondering what this could be, that makes sense. The size of the head really threw me off on this one.

Due to the coloration, I would say, for the species, Pogonomyrmex rugosus.

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).

Never use  color alone for an Id, it is far too variable a feature. This is far darker than any Pogonomyrmex rugosus male I have ever seen. Doesn't mean it is not P. rugosus, I just would not want to stake money on it.
