I do not think so. 7mm is very small for them. Lios are usually around 10-12mm. I'm not sure exactly what this is. Dorymyrmex insanus would be my guess.NVM

 

Could you have possibly measured 7/16"? That is about 12mm. And this does look like Liometopum in terms of body shape.

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).

Can you remeasure? I think this might be Tapinoma sessile.

I second Ys, it looks like T. sessile. It can’t possibly be a Lio queen if that is a fruit fly next to it.

Not at all. Completely different body shape.

 

It does look like T. sessile to me as well.

It's most definitely not Tetramorium immigrans since there is no post-petiole visible.  Tetramorium is under the subfamily Myrmicinae, all of which have two post-petioles and is very visible.

I remeasured and the queens are actually closer to 5.5 to 6 mm (sorry about the over measurement earlier!) Does that help with the ID?

I probably should have also gotten some pics of the workers and majors (?) too, but I didn’t

Also the queens might be poly/pleo because they group together and don’t attack each other at all

Not a Camponotus or a liometopum. Way too small.

Please read the information before posting, and based on another ID attempt I saw you make, I would recommend just listening to what the more experienced keepers say and learn from them. That's what I do a lot of the time.

T sessile. They enjoy founding in large groups.
