wasp - Macrocentrus nigridorsis - Female
Turtle Lake, 1621 1 3/4 St., Barron County, Wisconsin, USA
July 11, 2015
Gathering_2015. At mv light.

Moved from Macrocentrus.

tentatively ID'd as Macrocentrus nigridorsis Viereck
I collected an apparently identical specimen from the lights at the 2015 gathering.

It keys to M. harrisi DeGannt, sensu Muesebeck 1932, which I believe is now considered a synonym of M. nigridorsis Viereck. I don't have the most recent revision (Ahlstrom 2005), but I'm fairly confident this is the correct ID.
