Moved from Spiders.

New Genus
An entire new genus. Nice one, and thanks for figuring it out Jeff.

it's a new haplogyne family for the guide as well, which are poorly represented here.

I didn't notice that. Awesome.

It does look similar, but wouldn't explain the tufts of hair on the front legs. Can you fix your link picture below? Use the following code [thumb: 37470] except without the space. That will give you a thumbnail instead of a large photo. I'm going to play with this pic in photoshop and see what I can find out about those weird legs.

did some searching based on what you guys gave me
what do ya think?

heavy sexual dimorphism? maybe?

think Ariadna based on the first pair of legs, and the visible palp in this image.

Not a Kukulcania. Adult male Kukulcania's of various species are often light brown or tan with a spindly appearance.

I agree. I couldn't get a much clearer image from photoshopping, but they definitely appear to be "feathered". I don't know what other species have feathered legs, but this is the only large spider with them that I've ever heard of.

just edited this one. but I'll restore the original if you can do a better job.
What you are seeing as feathers are actually spines.

Thanks I wasn't sure what to call them. Your image looks just as good as anything I came up with.

double checked, and they are not spines, but rather lateral apophyses.

I'll stick with spines if you don't mind. I know I'll never remember this other term. :)

obvious feature I missed was the thick legs 1 and curved femur 1, which is typical of Plectreurys, as well as the spines.

A clear image of a lateral view and the differences between this and Ariadna would be obvious. Glad I had some doubt and didn't move it to the Ariadna page resulting in an incorrect ID.

same spider thanks for linking them.
definatley a mature male. ive come across this species a few times. i thought they were really cool lookin but couldnt find info on them anywhere.

Weird legs
I can't tell if those are tricks of the light or if your male spider here has feathered legs. I once found a spider with feathered legs like that, see below, but the carapace doesn't seem to match. I doubt they are the same spider. You may have to wait until a spider expert sees this one.

Black Spider
I'm going to assume that these are the same spider and link your images for you.

the location for other image is a mistake. I think they are the same too.

There is an Ariadna species in AZ, and this does look like an adult male.
