lebeau vs forbesi
Taxonomic question here: http://bugguide.ent.iastate.edu/node/view/44332

All-leps (which is supposed to be our new taxonomic standard) has forbesi split. Patrick, should we change this to R. forbesi?

Thanks!

Sounds fine
Sure, I'll make that right quick.

Thanks, Patrick!
The one thing that had me a little uneasy is that All-leps continues to list R. lebeau sensu strictu as a N Am sp. But as far as I can tell forbesi has to be correct.
