Steatoda - Steatoda - Female
Upton, Weston County, Wyoming, USA

I have permission from Jessica Peterson to post this photo, would like to get a confirmation species. I believe S. borealis, wanted to make sure not S. bipunctata.

Did she collect it?
This doesn't quite strike me as any Steatoda I'm familiar with so far. I happened to see it when you first posted it and I subscribed because I thought it looked unique, and there are Steatoda species in Wyoming I've never seen before.
I can say it's definitely not S. bipunctata; I've raised those before and they don't look like this, aside from the similar white line down the center and around the anterior abdomen (the center line actually starts out as white dots down the center in the immature ones), and pattern and body proportions (leg length seems too long) seem off for that species too. Seems real "shiny" as well, not something I would expect for either S. bipunctata or S. borealis.
And S. borealis is similar to S. bipunctata in body proportions as well, so I don't think this one is either of those. Both of those have a somewhat "grainy" appearance to their carapaces too, which doesn't seem to be the case in this one, but it's hard to really tell. Any other shots of it, or did she collect it by any chance?

So I wonder about some other Steatoda from Wyoming, an immature one maybe (if it's a Steatoda it doesn't seem quite adult yet, but I'm just guessing on that). There are Steatoda species I've never seen before, as well as ones that aren't yet represented on BugGuide. I truly wonder about S. grandis though. An immature of one of those perhaps??? Hope she collected it? :D

(Or else maybe another option could be some species of Enoplognatha, though that feels less likely in this case.)

This was quite a while back, the picture submitted was by a gal in Upton . I have a facebook page called spiders of Wyoming, so i get a lot of submissions, rarely are they from people who actually keep them, more or less just want to know what they have and if it's dangerous. Generally I can always id to family, sometimes genus and rarely species. This one through me as it did not have the typical markings of S. borealis, which is a lot of the Steatoda submissions. I will also submit a photo if i notice that they are missing in Wyoming's range on this site. Should i send this to Paula?

unique Steatoda
Ah, darn... would have been cool to verify it from an actual specimen. I totally understand the picture thing, that's the case with a lot of spiders here, and what I'm used to on other sites, too.
Paula might be able to tell you something, I would go ahead and show her, if you want. It would be awesome if she could confirm what it is.
