Any ideas on species? Very tiny workers

I think these are Temnothorax ambiguus or Temnothorax curvispinosus.

Certainly Temnothorax of some kind.

Perhaps T. illegalensis?

I cannot claim to know much of Eastern Temnothorax, so I can't distinguish between ambiguus and curvispinosus without looking thru the key.

Edit: I'm leaning towards curvispinosus because of those spots the workers appear to have on their gasters, ambiguus are not supposed to have those.

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).

The best way to differentiate between T. curvipsinosus and T. ambiguus is by the length of the propodeal spines on the workers. T. curvispinosus have much longer spines compared to the smaller spines of T. ambiguus.

We need better pictures in order to find the exact species maybe if you took a picture from the side we could see the length of the propodial spines. For now I think we can safely say its either Temnothorax curvispinosus or Temnothorax ambiguus.

For me its a mixture of being bored at school like OiledOlives and staying up until 4 am researching ants while staring at a small screen.

Thanks for all the replies. I'm not sure if I can get any better pictures of these guys from the side but I'll try.

Its fine if you can't but we just won't be able to verify the exact species.

Pretty sure their care is the exact same, so if you can't get picture of the spines I wouldn't worry about it too much.

Been keeping ants since January of 2021

Always try new things, even if its hard, hard is not impossible. We are smart and it's good to be smart but not too smart for your own good.

The dark band on the gaster of workers hints at T. curvispinosus. T. ambiguus tends to be all orangey with no black or dark brown on the gaster. There is also a tendency for habitat differentiation, with T. curvispinosus in woods, and T. ambiguus in fields.
Note; Queens of both species have darker gasters, so other characteristics needed to ID.

Antwiki is a great source. 

 

 

I'm also going to say T. curvispinosus.
