Assassin or Damsel? - Acholla multispinosa - female

Assassin or Damsel? - Acholla multispinosa - Female
Framingham, Middlesex County, Massachusetts, USA
October 30, 2005
Size: 2-2.5cm long
This cool creature was perched on the foundation of my house. At first I thought assassin bug, genus Sinea, but then I thought maybe it's a damsel bug. I can't find a good genus match in the Nabidae though - any thoughts?

female
Abdomen of female is much broader than that of male (1). This matches the illustration of the female in the reference cited.

Info on sex differential
Thanks, it's good to learn as I go, your explanation is appreciated.

Reduviid
I would say Reduviidae, my criterion being the constriction behind the eyes (the "neck").
In addition (for what it is worth) George McGavin's Bugs of the World states (of Nabids):"Nearly four hundred species, each less than 12 mm (0.5 in) in length, have been described from all the faunal regions of the world.".
Your bug is too big.

I agree.
Amazing! Second shot I have found here TODAY of Acholla multispinosa. Tom Murray got the other one. Both shots are superb, both from Massachusetts I believe.
