If the workers really are 2 mm (the queen would probably be smaller than 6 mm), it could be a Monomorium sp. Maybe M. minimum or M. emarginatum.

 

Thank you for posting a properly-formatted ID thread! :)

Photographs from the underside are very rarely useful for identification.

If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.

 

Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.

Black lives still matter.

There are no M. emarginatum in Cali. I do agree with Monomorium sp, but I do think we need better pictures, not from the underside of the ants.

I meant to suggest M. ergatogyna, but I made a little typo... :3

 

But yeah, I would say these are some Monomorium species. you can use this guide to help ID them, if you're willing to take a stab at it yourself.

after looking through this link I'm 80% sure they are Monomorium ergatogyna.  The only other one that looked possible was  Monomorium viridum but based on distribution on the link they should not be here

Well.. the wiki article says there are here too so no i am leaning more towards  Monomorium viridum. Does the size match? workers are between 1 and 2mm, queen is 5 or 6mm. They look almost solid black and shiny even under a spot light and a jewelers loupe, and the gaster shape seems the closest
