Added a Picture

I just added what I believe to be ventral view of this spider, or its friend.. I'm not 1,000% sure as it's a couple days different time. But I wouldn't have been around anything else with similar photos then. Maybe this photo will be enlightening?

I was hoping that you had sent him the specimen --- wasn't he interested in looking at it?

it was in 2008

And I didn't collect it. I only photo the critters, which I know limits me on getting them ID'd.. :) Is this ventral view helpful by chance?

… Andrew Williams, 6 February, 2010 - 11:05am

Best would be to ask Dr. Huber. There's a nice long recent article (or two -- available from Zootaxa), but I don't presently have copies. :-(

i emailed Dr. Huber

Be interesting to see what he thinks. Thanks for the suggestion. That was a good idea.

potential species notes from Dr. Huber

"The pattern is indeed unusual, and what immediately comes to mind is Pholcus crypticolens. This species seems to be widely distributed in Eastern Asia (Japan, China, Korea, eastern Russia), but I am not sure if the mainland records of P. crypticolens are actually P. spilis, a very similar (and closely related) species currently known from several places in China. In any case, the distribution seems to be affected by humans, and this makes is slightly less surprising to find it in the USA."

I'm beginning to think that this is your standard Pholcus phalangioides -- particularly if Andrew says he found it in the basement.

unknown species

We just heard back from Dr. Bernhard A. Huber, at the Alexander Koenig Zoological Research Museum, in Bonn. He feels certain that it is not any of the "usual suspects" and is hoping that Andrew can come up with another specimen (or two).

So, for now, we could perhaps place this in a "Pholcus sp." (or similar) category.

garage + note from U.

It was actually in the garage, closer to outside. I'm working on your University idea. Apparently a new species was just discovered recently in KS, on the KU campus! Will be back with whatever I find out. :)

Andrew,

How about some additional details: approx. size, where did you find it, etc.?

before tracking, but

I can say that it was found in a Kansas City (Kansas side) garage. Leg span going by memory, was about 30-35mm. Body I don't know. This was before I knew to log additional data about subjects.

… Andrew Williams, 19 November, 2009 - 11:01am

Pholcus, maybe

Pholcus muralicola is found around rock walls in limited areas of Kansas (and only KS), so that is a slight possibility. There is also Pholcus manueli that seems to inhabit the eastern half of the USA. You can scratch off phalangioides, as I don't think this is one. Their are more eastern oriented Pholcus that haven't been described yet, too. Personally, I have only seen phalangioides with my own two eyes...I haven't seen photos of the other species. Maybe some other spider people have? I wonder, do you happen to have any photos of the ventral side, particularly the sternum area?

… Mandy Howe, 18 November, 2009 - 9:25pm

I think we can eliminate P. m

I think we can eliminate P. manueli. Gertsch (1937) writes "abdomen ... without definite pattern".

additional photos + thanks

Unfortunately this was done before I knew to get pics of both sides of spiders. I posted a few spideys like that yesterday. You've got some good lead ideas here. Hopefully I can find some good reference images. This one appears to have a pretty well defined pattern. Maybe I'll get lucky and find something that matches.

… Andrew Williams, 19 November, 2009 - 9:55am

How close is your nearest university biology library? The only reference article I see listed for Mandy's suggestion is this:

Maughan, O. E. & H. S. Fitch. 1976. A new pholcid spider from northeastern Kansas (Arachnida: Araneida). J. Kans. ent. Soc. 49: 304-312.

[Update: I found the P. muralicola via JSTOR. Based on a quick read, I don't think that this is what we have.]
