Antlike Jumping Spider - Synemosyna formica -

Ballston Lake, Saratoga County, New York, USA
June 8, 2012
Size: ~ 5 mm

It was in the weeds, on a leaf of jewelweed. It crawls like an ant, and holds it's front legs forward and waves them so they look like antennae. I captured it, and will take more pics. ID help appreciated.

Synemosyninae?

According to a description of the subfamily Synagelinae by Wayne Maddison at the Tree of Life web project, members of that subfamily are, "Antlike jumping spiders distinct from the synemosynines in having an embolus articulated against the tegulum, and from waving their second pair of legs (instead of the first) like antennae."

Since this spider waves its front pair of legs like antennae, it is presumably in the subfamily Synemosyninae. (I don't know about the embolus and tegulum.)

Wonders never cease!

What a great find.
