Clypeal notch

I may eventually be good at diagnosis of at least the easier genera. In the meantime, I can appear wherever a species announces itself with a single, unique trait. E.g., Halictus ligatus and Megachile pugnata are unmistakeable for conspicuous genal processes. Another case: In DiscoverLife there are 96 possibles for Oregon Osmia. Osmia inurbana is the only answer for Middle of rim with distinct, narrow, acutely angled, triangular notch in Oregon.
