Cheiracanthium erraticum

This was in a pitfall trap (in propylene glycol, so no live photos). I think the pattern is sufficient to identify it, but I attempted to check the epigyne to make certain. This doesn't appear to be fully developed, so I'm guessing it's immature. The Belgium and French spider website includes a photo of the female chelicera with an arrow pointing to a short second row of three teeth (behind the longer row of teeth). It's not explicit that this is important for ID, but supposing that might be why it's arrowed, I looked for it on my specimen. It's hard to see as the area is covered in hairs, but I was able to confirm that mine did indeed have the row of three teeth looking just as shown in the photo at the Belgium and French website.
