Remeasure?

 

I think this is Tapinoma sessile, but 8-9mm is way off for that species.


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).

Yep, Tapinoma sessile.

We sure it isn’t liometopum or brachymyrmex? It doesn’t look like tapinoma to me (unless the cali specimens are different from eastern ones)

I'll see if I can get some better pictures soon. All I have right now is my phone and an upright microscope. I have one of those cheap digital disecting scopes on the way, to get better depth of field pics.

I was thinking the exact thing. The head shape looks a lot like lio. But then the shape of the body looks a bit different.

This is almost certainly T. sessile. L. occidentale and luctuosum are usually over 10mm. B. patagonicus has a vastly different head shape as well.

4 segment rule, people. In the US it's completely unique to Tapinoma, even very similar genera like Technomyrmex can be separated with it.

Oh wow I didn’t know that was a thing. That makes things much easier.
