Found in a shed. The slightly unusual surface is some burnt wood I found out in the forest. Still no luck with the posterior epigynum angle for this species, though I was being extra careful to minimize pressure on the abdomen as I think this spider has an egg sac coming soon.
First time observing this species mating!
Juvenile C. severus. Larger than some adults I've found! From what I've seen, juvenile females have somewhat lighter faces than the adult females.
