Cactus Bug - Narnia femorata

Cactus Bug - Narnia femorata
Redington Pass Road, W of Redington, Pima County, Arizona, USA
September 14, 2012
I wonder if this might be Narnia snowi; there are many N. femorata around, but I'm not sure how to distinguish between the two; this one has a stronger white line across the wings, a lighter colored pronotum, and slightly thinner hind legs than the N. femorata. This one was found on a Fishook Barrel Cactus (Ferocactus wislinzeni). The nearby nymphs also have a much whiter pronotum than the ones I commonly find around N. femorata. Thank you for any suggestions.

N. femorata…
The two species can be difficult to separate out, but N. femorata sometimes has a slight trace of a white band (rather than a strong line) across the elytra (more distinct in N. snowi), and N. femorata is also typically narrower in width when compared to N. snowi.

See reference here.

 
Thank you
I appreciate your help - it often causes me confusion. This helps.
