Identification

Epigynum:

Palp (better images needed):

Distinguishing B. utahensis from C. brunneipes:

So I looked at these carefully today, comparing only the males of spiders I think the ID is 100% correct.

vs.

Here is what I see... for differences.

Coriarachne brunneipes males tend to have a

1. more elongated abdomen

2. less coloring on the legs

3. longer leg segments

4. carapace tends to have deeper 'grooves'

5. Perhaps the white marking on the abdomen tend to point more forward toward the edges.

Now I think there is the possibility that many of the Coriarachne brunneipes photographed were just 'thinner' than the Bassaniana utahensis, but up to now those points seem to be consistent.
