Found in my basement. Is this Trachelas, or Dysdera crocata? I always get them confused.

Looks like a Woodlouse Hunter to me. I see how it looks similar to Trachelas. Looks like the cephalothorax of Trachelas is pitted where Dysdera crocata appears to be smooth. Shot that shows eyes, or fangs would nail it I think. I'm pretty sure though.

Yep, Dysdera crocata
Dysdera crocata have "porrect" chelicerae, which means they are extended forward, as is seen in your photos.
