Harvestman, we think

Small black spider, huge pedipalps
January 19, 2010
Hello. I’ve been going crazy trying to figure out what type of spider this is. I’ve seen two inside my house and one outside. Most notable are the pedipalps (at least I think they’re pedipalps — I’m no expert) that are actually longer than the rest of the spider’s body. Also, it walked very robotically and slow instead of the typical spider “scurry.” It had four pairs of legs.
I wish my photos were better. Both spiders I was able to photograph were already dead. The first photo is a profile view of the spider. The last one is a top view. Thanks for your time.

Hi Lisa,
We have had a few misidentifications in the past few days, so the possibility exists that we may not be correct. We don’t believe this is a spider, but rather a Harvestman in the suborder Laniatores.  There are some photos on BugGuide that look similar, but alas, your photos don’t  show some of the details we would like to see.


Hi, Daniel,
Thanks so much for responding — and so quickly at that!  After some internet research, I suspected it was some kind of huntsman.  I just got a sweet new camera, so if I see another and can get quality photos, I’ll be sure to submit them.
What’s also interesting is that I’ve seen two tiny pseudoscorpions in my bathroom.
Thanks again!

I was looking at the pictures of the arachnid in the “Huntsman, we think” posting and to me it looks a bit more like a whip scorpion or tailless whip scorpion than a huntsman. This could explain the huge pedipalps.
