Body:
1. Location of collection:  Glendale, Arizona, in my pool.

 

2. Date of collection: 5-23-17, the date of this post.


3. Habitat of collection: urban, desert, landscaped yards.


4. Length: 4-5mm, measured once she was in the test tube.


5. Coloration, hue, pattern and texture: Dark brown head and thorax, dark brown gaster with lighter stripes between gaster sections, light brown legs, bald and shiny.


6. Distinguishing characteristics:  I used a macro lens on my phone to get these photos, so whatever you can see is what I can see.  She is too small to make out any details with the naked eye.  Based on the photos, I do not see a petiole node.


7. Anything else distinctive:  Once dried off she was pretty active, but also doesn't seem to startle easily, if at all.  While taking the photos she just sat there cleaning, even when moving the test tube.


8. Nest description:  No nest.


9 . Post the clearest pictures possible of the top, side, and face of the ant in question, and if possible, their nest and the habitat they were collected in.

 

 

Here is an album of photos, some of which are pretty decent:  http://imgur.com/a/FGR6a

 

 

Here's a quick video of her cleaning herself:  

 

 

 

Found this lady floating in my pool at about 5:30 A.M. this morning.  There were probably 8 - 10 others, but they were all deceased.  I pulled her out, put her on a paper towel and once she dried off a bit she was very active.

Thanks for the input T.C.

My guess was Brachymrymex due to the small size. Possibly B. depelis or B. patagonicus.

This does seem like Brachymyrmex, though isn't it too early for them?

Possibly, but the mating chart does show several sightings for May. Quite a few actually.

I would consider Nylanderia spp.

Thanks Void, I'll keep that in mind. It might be time for me to invest in a cheap microscope.

Seems too small for Formica.

 

Brachymyrmex and Nylanderia are possibilities.
