Austin, Travis County, Texas, USA

Size: 2.5mm
Found under some cardboard that had been laying outside for a while, near a nest of termites.

Immature. At first glance, I thought it was an ant. Runs very fast. Gestalt and behavior reminds me of a Corinnid, but I cannot get it to key out to any family. Maybe it'll key upon adulthood. I'll attempt to raise it.

Corinnid? This specimen has 2 claws, 8 eyes, no precoxal triangles, 2 pairs of ventral spines on anterior tibiae. I can't decide whether it has abdominal scutes (Castianeirinae group). No apparent 'cusps' on anterior legs (Trachelinae group), but I'm not sure what cusps should look like.

Endites appear to be "concave ectally" (Clubionidae), but there are clearly no precoxal triangles (hence not Clubionidae). Possible Leocranid?

My gut is telling me Corinnidae, Castianeirinae.

Moved from ID Request. I agree with your gut. I'd even say that the eyes match very well to Castianeira.
