Anisoptera, the first of two volumes on the Odonata in the series Encyclopedia of South American Aquatic Insects, encompasses the large dragonfly species. A brief review of the biology of the group includes illustrations of the main morphological features as well as explanations of alternative systems for naming the wing veins and other structures. The review is then followed by keys to facilitate identification of the adult dragonflies and the known larvae, allowing the user a high probability of identifying his specimens correctly. In addition to anatomical features, the keys include the known ranges of the species, synonyms, and citations of literature in which more information about each individual species can be obtained. These citations are compiled in an extensive bibliography. To provide the user with the best possible opportunity to distinguish the species, the keys are richly illustrated with pen and ink drawings of thousands of individual morphological structures, arranged in 797 figures.
