These are a dominant spider species in my basement, but unfortunately since they are so darkly colored and like dark corners so much I never manage to get decent photos. Can anyone tell who this is? They appear black until you get really close, and I only see them in the basement, never in the rest of the house or outside. Robust, run-out-and-grab-prey style hunters, seemingly more active at night, I saw one take down a baby red-backed salamander last year that was wandering foolishly across the floor downstairs during baby dispersal season. Quarter sized.
