Spider - Cicurina brevis

Spider - Cicurina brevis
Boxborough, Middlesex County, Massachusetts, USA
November 3, 2005
Size: 5mm
Found this under a rock.

Moved from Callobius bennetti.

I think this one and also this one:

...are genus Cicurina rather. What do you guys think?

Excellent catch!
Certainly look like

That would help to clear up some of our earlier confusion as removing those wolf spiders did earlier. Thanks.

C. brevis looks good!

i think this could be a spide
i think this could be a spider in the family Amaurobiidae

I agree... Amaurobiid
This appears to be Callobius genus Amaurobiid. They are common in dark areas (storm cellars, under fallen bark, stones, etc.) in New England. I found one nearly identical to this specimen this summer (in MA), and was able to ID as a Callobius genus spider. (Quite possibly C. bennetti, but the species ID was based off a list of known species within New England, and not an ID key).

Compare to this image.

We're still confused
by this group of spiders pictured below in an older comment. Don't know the correct vocabulary to describe what we're seeing, but Tom's spider seems to have a circular flattened cephalothorax, where the linked image of Callobius has a domed, almost cylindrical appearance. Would appreciate more info on how to separate these spiders. What visual clues are we missing?

to Callobius guide page. Thanks.

We'll be curious
to see what comments you get on this one. We have a number of sort-of-similar images floating around. Your seems probably the closest match. We can't quite make out the eyes on to know. While Lynette's seems to have a clearly different eye arrangement. Hers has an eye arrangement that is similar to one that's in the guide under the larger Amaurobiidae , but it's the only Amaurobiid with that eye arrangement. As you can probably tell, we're thoroughly confused, and consequently waiting expectantly for the comments on this current image.

Confusing spiders
They all look similar, but I think the thorax on this one is more flattened, rather than barrel shaped like the others.
Looks like you've been doing lots of work getting things identified. Thanks for the help.
