Western North America Bee Keys

[Maffei, Clare J]

Hi Folks!

Does anyone have a catalog of species keys for bees in the West? Canadian overlap works too. I am finding some papers, and obviously understand the taxonomy is very unresolved. Any literature you can suggest is very welcome, especially if you can share pdfs. No genus left unturned! 

Please and thank you!
