Spring Spider on Barn Roof in BC, Canada - Callobius

Spring Spider on Barn Roof in BC, Canada - Callobius
Victoria, British Columbia, Canada
March 8, 2006
Size: 2 cm
This guy was hanging out on the roof above my head as I did a workout in the unheated barn. Body is 2 centimeters long,with legs 3.5 total. This barn roof is absolutely littered with webbing and dead old carcasses of this same type of spider, all sizes. Good thing I don't have arachnophobia, but it still bothers me a bit. That's a lot of spiders! And to me, they have an aggresive look, moving hunter type, red legs, strong thorax, etc. Looking through the lists on this site, there are a number that seem close, but not quite, ie. brown recluse, hobo, etc. No violin marking that I could make out.

So, I am wondering if anybody really knows exactly what this is. My primary concern is if it can bite and be toxic, to me. Like I said, there's evidence of a lot of them and I have a number of items in storage in the barn. Thank you for your time.

Moved from Hacklemesh Weavers. Pretty certain this is genus Callobius.

Reminds me of...
Gnaphosidae - Ground Spiders but the location is obviously not the ground. Also reminds me of amaurobiidae.

BC Spider
Thanks for both your comments. Judging by the other pictures of Gnaphosidae, I agree that that is what it is. Although the amaurobiidae is definately similar. Looks I don't have to worry about these. Cheers.

I think it might be either an Amaurobius or Callobius in the Amaurobiidae.

I agree.
Definitely in the Amaurobiidae. These spiders are very common in the Pacific Northwest.
