Kevin it looks like the right species, but I'll have to look for an adult next time. Thanks for the ID.

 
Side comment
Tom,

Did you get my note about the mystery spider? It was posted here:
http://bugguide.net/node/view/296225

I'd really like to see a habitus image and verify the right collection details, if possible.

-Kevin (wishing you all a "good slide" into the new year)

Cheiracanthium cf inclusum (immature)
An immature specimen (we should have known that, I think). But I agree with Mandy that this is a Cheiracanthium (long first leg pair) and most likely C. inclusum (bright lemony color vs. more ashen-grey of C. mildei).

-Kevin (discarding this specimen)

Maybe.
A good clear view of the top of the carapace helps on this. If it has a longitudinal groove it's Clubionid, if not it's long-legged sac spider.

 
Long-legged Sac Spider
I vote for Cheiracanthium. The legs are quite long and thin and I can't really see a groove in the carapace at all. I don't see a hair tuff on the anterior abdomen, either. My guess is that this is the C. inclusum species, but only because it looks like this spider was 'outdoors' (as in away from human habitats). The other species, C. mildei, is actually more common in the NE than C. inclusum...but it is more often found indoors or around human habitats. Besides range/area, I wish I knew some better ways to tell the difference between these two species. I'm sure the information is out there, I just haven't found it yet.

 
It was outdoors
But don't let the picture fool you. I take them home, and photograph them in my kitchen, and use a leaf for a more aesthetic background. I'm confident with your identification, but I'll wait for Kevin to chime in after looking at the specimen. Kevin just received a bunch of spiders including this one yesterday, so he should be able to tell for sure if it's C. inclusum.
Thanks for all the info Mandy!

 
Good idea...
...using a leaf is a really good idea! Something I have never thought of. I hope you don't mind, but I might steal that idea at some point. lol.

 
You won't be stealing anything
Just using one of many ideas we all get from one another. I've taken plenty of pictures on plain backgrounds, and it shows the bug nicely, but it doesn't look anywhere near as good as a natural looking background, if it's any color leaf, bark, sand, or anything else that the bug might be on outside.
I'll be looking for your pictures. They look really good already.

 
Well...
Thank you, but...technically I'm still trying to harness the unimaginable power of my point 'n shoot digital camera with styrofoam bowl flash diffuser. LOL!! Your work is really good. I have some field guides that feature your photos! I've checked out your pbase gallery a few times, too. All very beautiful! Some of my favs that stick out are the sea lamprey, the close up of the Santinezia harvestmen, the Trinidad Chevron Tarantula in the moss (it looks so feathery and soft, like a toy!), the grumpy looking American Toad, all the fungus pics,...well I guess too many to list! So cool!!

 
Point 'n shoot
I think you've harnessed your camera very well, and have plenty of nice detailed pictures on bugguide. And not just spiders:-)
Thanks for the compliment. I like to photograph anything that moves, and some that don't. I guess you could say I spend too much time with a camera, but I'm having fun, even when I stay up way too late on the computer, or looking for moths by the porch light.

 
Hehe
I know all about staying up too late. lol. We bug folk are compelled, I guess you could say. :)
