While we were preparing our book The Naming of Australia's Dragonflies, each of us consulted the etymologies given in A Checklist of North American Odonata: including English name, etymology, type locality, and distribution by Dennis R. Paulson & Sidney W. Dunkle (2012). When we met for the first time at the European Congress of Odonatology (2016) in Tyringe, Sweden, amongst our many conversations we agreed that we had found some entries which could warrant a review. Also recent work by Matti Hämäläinen had shed additional light on some people commemorated with an eponym. We contacted Dennis, the senior author of the checklist, and offered to provide amendments for some of the definitions, and he readily agreed. With this encouragement a number of amendments were suggested for inclusion in the next edition of the checklist. However, our research which included perusal of the original description for every taxon, revealed much information that could not be encapsulated in the phrase or sentence to match the checklist format. When assembled, it was fast approaching the size that warranted publication as a book. If a short biography of each author was included, a book it had to be. We have many people to thank for help in finding copies of the more obscure references. Once the etymologies were essentially complete, and we had started on the biographies, Dennis recruited Harold "Hal" White to help with sourcing photographs of American practitioners and to give a point of contact for those entomologists still, or recently, active in this field. Publication and Distribution presented another problem. This was not the sort of work that would be snapped up by a commercial publisher who would then market and distribute it worldwide, and it was not feasible to distribute from somewhere as remote from America as Australia (or Europe). Whilst many people now prefer publications as a pdf, neither of us would be happy if that were the only medium to be made available. Busybird Publishing, who prepared the volume on the Australian taxa, introduced us to the concept of Print On Demand, and that was the solution we had been seeking. In November 2018 a new edition of the Checklist was published which required us to include an extra four species and another author's biography. And here you have the result of that team's work over more than two years.

Dragonfly Genera of the New World is a beautifully illustrated and comprehensive guide to the taxonomy and ecology of dragonflies in North, Middle, and South America. A reference of the highest quality, this book reveals the striking beauty and complexity of this diverse order. Although Odonata -- dragonflies and damselflies -- are among the most studied groups of insects, until now there has been no reliable means to identify the New World genera of either group. This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia. For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.

This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.
