Specimen: kmp-6253
I sure would like to see a Cicurina arcuata specimen or two, to compare with these -- the drawings of the epigyne and spermathecae seem to be so similar in appearance.

Specimen: kmp-6253

 
I think this
(and the others here under C. robusta) must be C. arcuata. I just spent some time identifying this spider -



which has the same epigyne and according to Chamberlin and Ivie, 1940 C. robusta has a grey abdomen without a pattern while C. arcuata has a pattern like these have. Also C. robusta's range is given as "Rocky Mountain and Great Basin States" in How to Know the Spiders while C. arcuata is "New England and adjacent Canada south to Georgia and west to Louisiana and Missouri."

Edit: After reading through a number of papers it seems that there is considerable confusion regarding these two spiders. Kaston seems to give an easterly range for C. robusta in his 1948 paper but the range I quoted above in his book.

Thanks Eric, it looks like a good match. I see you found some of these spiders in your pitfall traps ay least. And no matter how hard I try, I'll never see all the cool bugs just in my yard:-)

Cicurina robusta?
Looks to me like that species anyway. Nice images! I wish I could have had the chance to find live ones myself when I was back there....
