The Bee Genera of North and Central America (Hymenoptera:Apoidea)
By Charles D. Michener, Ronald J. McGinley, Bryan N. Danforth
Smithsonian Books, 1994
ISBN: 1-56098-256-X
Cite: 55160 with citation markup [cite:55160]
This work (written in English and Spanish) describes 169 genera of the region. Two keys are inluded: to the families, and to the genera of each family of bees of North and Central America. I find the detailed, and labeled, anatomical drawings useful, even without a microscope. (Of course, specimen and microscope make the work far more useful!)
