I will work on this as I know what they are but just cannot remember their names currently!
So I will go look them up and give you some links if possible!
Just give me time as I am not currently doing well!!!

The first one may be
Olios giganteus.
No clue on the second one but it's a nice looking spider.

I have those spiders as well the first one is Olios fasiculatus and I am not sure on the other one,
My Olios had an eggsac that just opened up a couple of weeks ago. They are really fast little babies too.

The second one reminds me of my favorite true spider (but its not it)... the Kukulcania arizonica.

For the second spider....
What about a species from the family Plectreuridae? There are three species native to Arizona listed
here. Of those three I was able to find
pics of Plectreurys tristis. I think it sort of resembles the spider you have.
Edit: Check this out:
The Spider Family Plectreuridae.

So Duke, which species do you think that second spider is? I dont clearly understand.

I see those black spiders under almost every rock I flip. The interesting part is I've seen a bunch of them next to ant colonies. Apparently they eat ants. I found that pretty cool.

I'm not sure what K. arizonica looks like, but I have found a ton of spiders of the Kukulcania genus. I have two of them right now. They might be K. arizonica not K. hibernalis like I originally thought.

Ok from what I just read if they are under rocks then its most likely going to be Kibramoa arizonica as they tend to live under rock and debris, while the Kukulcania hibernalis tend to live around human habitations and make webs in cracks and under boards! It just very well may distingish them from each other!
I am more inclined to think its K. arizonica then the others.
However, please note that all of these are from the same family and are very closely related and that includes in looks!

I don't think it's terribly hard to differentiate between the two. Kibramoa arizonica is tiny and K. hibernalis is pretty large for a true spider.

well I found at least 30 of these spiders, some had more tannish abdomens than others, I had a few more collected. but I released them as I contuinued to find more pedes, and I needed to let them go for the space. They were all under rocks, and logs. and they had funnel type webs. Does that help better?

I stick with it being Plectreurys tristis. The picture on
this page looks like your spider. Though the info given says they spin "unkempt webs" I think the paper from the AMNH I linked to above describes this species as living in tube webs under rocks and debris. The info given regarding Kibramoa spp. on the page above (one dwells in caves, another was found only at higher elevations than P. tristis, and another is more slender than Plectreurys) tends to not mesh with your spider in my opinion. It cannot be K. arizonica as Kukulcania spp. are cribellate spiders, plectreurids are not, and what little of the eyes I can see on your spider does not seem to match the eye formation of Kukulcania spp.
But this is all conjecture. Take it for what it's worth.

Hey David have you seen some good pictures of their eyes online? That just may be a great way to determine this! All three of these species are so close together that I think the pictures are doing us no good what so ever!
But eye arrangement could be the way to go!!!
