Scoliidae (Hymenoptera) of the Lower Río Grande Valley.
By Porter, C.C.
The Florida Entomologist 64(3): 441-453., 1981
Full Text (Image)

Charles C. Porter. 1981. Scoliidae (Hymenoptera) of the Lower Río Grande Valley. The Florida Entomologist 64(3): 441-453.

Abstract

The Lower Rio Grande Valley scoliid fauna includes 5 species: the aestivally common Trielis octomaculata texensis (Saussure), Campsomeris tolteca (Saussure), which abounds throughout the year, and the sporadically encountered Campsomeris completa Rohwer, C. hesterae Rohwer, and C. ephippium (Say). The Trielis seems to be of old Sonoran origin, while the Campsomeris are Neotropic species, some of which invade Sonoran habitats. Valley populations of T. octomaculata and C. tolteca differ in phenology, activity temperatures, flower selection, and habitat preference. Campsomeris hesterae has not been recorded previously from the United States.

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.
