I think it’s a red sack spider, not a wood louse its fangs aren’t that big. What do you think
Looks like a woodlouse hunter to me, actually.
And you totally made up the Red Sack Spider. So we can rule that choice out. The Woodlouse Hunters have big fangs but they are unusual because they curl horizontally toward each other. The spider’s left fang is visible in the photo. It is almost black in color and mostly obscured by other appendages.
