Tiny Spider with horn (tooth?) on palps - Dictyna calcarata - male

Tiny Spider with horn (tooth?) on palps - Dictyna calcarata - Male
Albuquerque, Bernalillo County, New Mexico, USA
July 3, 2013
Size: body 2 mm
This tiny spider was sitting on the patio table just waiting to be photographed. I guess the recent rains we've finally been having is driving the spider into the porch area. I'm sorry the photo's aren't better but he was pretty tiny...I hope someone can ID him, Thanks

Moved
Moved from ID Request. After some further checking I feel pretty sure about this ID.

The face makes us think of Dictynidae
but it's a tough group to get to know.

 
...
I agree with Dictynidae. I suspect the horn is significant. If I get some time I'll try and look through Chamberlin & Gertsch 1958 and see if the options can at least be narrowed down.

 
Perhaps [i]Dictyna calcaratus[/i]
There are a couple of Dictyna species that have a horn on the pedipalps. The largest ones appear on D. calcaratus. This is a tough family (I've been wallowing with some unknown females for some time), but there may be some hope for your specimen. Great series of pics!

 
Dictyna calcarata
Good call, I think you've got it right on!

After looking through, I think this has to be in the longispina group. Of those, only D. calcarata seems to have the horn taking up almost all of the dorsal tibial surface as here. D. formidolosa comes the closest, but has the horn somewhat smaller and is more of an eastern species.

 
Dictyna calcarata
Thank you all for your input in ID'ing this little guy. Normally I don't submit unless I can't make any progress, and this one had me stumped. Thank you "Kyron Basu" for your interesting article on how you do your photography...sure beats chasing a bug all around yelling at him to hold still.

 
...
You're welcome!

And lol, yes, it is easier than chasing them around... although I still have to do a bunch of that for the habitus photos!
