Rosser William Garrison. 1994. A synopsis of the genus Argia of the United States with keys and descriptions of new species, Argia sabino, A. leonorae, and A. pima (Odonata: Coenagrionidae). Transactions of the American Entomological Society 120(4): 287-368.
A synopsis of all 29 species of Argia occurring north of Mexico includes keys to both sexes based primarily on caudal appendage morphology in males and morphology of the mesostigmal plates in the females, diagnoses, distributional notes and diagnostic illustrations.
Three new species, A. leonorae (Holotype male.-MEXICO: Nuevo Leon state, in FSCA), A. pima (Holotype male. - U.S.A.: Arizona, Pima Co., in USNM), and A. sabino (Holotype male. -U.S.A.: Arizona, Pima Co., in USNM) are described.
Damselflies of the NortheastBy Ed Lam
Biodiversity Books, 2004
A lovely little book, just under 100 pages. Covers all 69 species/forms of damselflies from the northeastern US (Virginia northward) and eastern Canada. It should be useful for all of the eastern US. Each species account is a full page and includes: life history, range map, flight dates, identification tips, detailed illustrations of both sexes, and smaller diagrams showing anatomic details. There is an introduction to damselflies with detailed diagrams explaining anatomic terms, and there are two pages of references. The book has superior typography and design.

Common Dragonflies and Damselflies of Eastern North AmericaBy Richard K. Walton and Greg Dodge
Brownbag Productions, 2004
Stunning close-up videos of common dragonflies and damselflies. Video showing behavior and a variety of angles is a great supplement to a field guide. 50 widespread eastern species are covered in a one-hour DVD. Sequences show life cycle and habitats, so it is more than a field guide.
Coverage of North Carolina species is particularly good, since one of the authors is based there. The footage of damselflies is especially welcome, since there is no in-print field guide for the eastern US.
My only wish is for a booklet to accompany it, and subtitles. (There are explanatory notes included in the DVD.) My copy had one minor glitch that only showed up on one DVD player, but not on another. This was not a fatal flaw, only annoying. (I have seen similar problems on other commercial DVD's.)
