I have no clue! Red house spider?
The long chelicerae and fangs make me think of a woodlouse hunter, but the abdomen is much darker than one’s I’ve seen before.
That’s been the most common from my research I’ve seen, but I agree, the coloring through me off. Harmless though, right? Are they common in basements? I get the craziest things down there and it’s finished!
Very harmless! If your basement is damp in any areas, isopods can be attracted to the moisture, and where isopods go so too will their hunters.
Mostly harmless. Like most spiders they have venom and could bite in self defense but are not considered to be of medical significance – everyone’s immune system is different though. Edit: and yes, this is Dysdera crocata, filed. 🙂
