Encyclopedia of South American Aquatic Insects: Odonata - Anisoptera: Illustrated Keys to Known Families, Genera, and Species in South AmericaPaperback, 17 November 2010

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 and explanations of alternative systems for naming the wing veins and other structures. The review is followed by keys to facilitating identification of the adult dragonflies and the known larvae, allowing readers a high probability of identifying 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 for distinguishing the species, the keys are richly illustrated with pen and ink drawings of thousands of individual morphological structures, arranged in 797 figures.
