The Bee Genera of North and Central America (Hymenoptera:Apoidea)
By Charles D. Michener, Ronald J. McGinley, Bryan N. Danforth
Smithsonian Books, 1994
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!)

The Sting of the Wild: The Story of the Man Who Got Stung for Science
By Justin O. Schmidt
John Hopkins University Press: Baltimore, MD, 2016
This book is useful in dispelling myths about broad groups (particularly the oft-maligned Mutillidae). The Appendix contains the rankings for 83 species and includes all ranked species. It's also worth noting that this does mean that the majority of species are unranked, so caution should be taken in creating sweeping claims (as often done on rather erroneous Internet memes).

The Hymenoptera of Costa Rica
By Paul E. Hanson and Ian D. Gauld, editors
Oxford University Press, 1995
A comprehensive treatment of the biology, systematics, and diversity of Hymenoptera in Costa Rica. Keys to superfamilies, families, subfamilies and in many cases, genera are included. Given the high level of biodiversity of Hymenoptera in Costa Rica in comparison to most areas of the world, this is a valuable reference book for students of Hymenoptera in any part of the world.
