Tetrix - Tetrix arenosa - female

Tetrix - Tetrix arenosa - Female
Elma at 49 52 36.3 N 95 54 24.9 W, Manitoba, Canada
May 12, 2012
Size: <15 mm

I think this is T. arenosa
The top of the pronotum looks too flat, and the fastigium too short and narrow for T. ornata. Paratettix cucullatus is very similar, and sometimes at this angle it is difficult to tell it from T. arenosa. A view from directly above is best to tell these two apart, because it shows the width and shape of the fastigium best.

I'm not sure if T. arenosa is even supposed to be found so far north as Manitoba, but that's what I'm going to call it (with a tiny bit of doubt).
