Moved to Theridiosoma gemmosum - JUVENILE
Moved from
Mysmenidae
. Mandy's arguments all make sense and tarsi do not appear as long as metatarsi.
From Mandy Howe:
(re: RC's comment on this one: most palps of mysmenids are huge, too, plus this one doesn't look mature anyways and males of course have slightly swollen palps early on before they get huge, plus the pattern is just like T. gemmosum and femurs I & II are swollen, long trichobothria on the last tibiae in 3rd view, all as in T. gemmosum -- plus male mysmenids would have a visible clasping spine on their front leg somewhere and I don't see that, but maybe it's not there until they're adult? not sure)

Maybe I'll get lucky
and find a mature spider later this year that looks like this one.
BTW Lynette the 2 links in your comment didn't work when I clicked on them.

=] Link fixed
I set that up incorrectly... I thought they were two separate links, but it was one really long one.

From Rod Crawford:
Definitely not a Theridiosoma. Males of Theridiosoma have massive
palps:
here
.
The palp bears some resemblance to a Maymena, but (assuming that name
hasn't been changed too) they aren't recorded from New England.

I'm not sure. The drawings by Roberts and Wiehle seem to show a pedipalp that is "stubbier" in appearance.

You may be right about this species -- I'm not that familiar with it. I see now, though, why the pedipalp is slimmer: it's a subadult male. :-\

(I'm going to discard the specimen.)
