Résumé
This beautiful volume, with hundreds of fascinating hand-drawn illustrations, completes the two volume work on the order Odonata in the Encyclopedia of South American Aquatic Insects.
The Zygoptera volume encompasses the relatively small dragonflies, often called damselflies.
The sections on the morphology of the adults and larvae are followed by brief discussions of ecological and zoogeographical factors influencing the distribution of the dragonflies and instructions on the various methods used to observe, collect, preserve, and examine specimens.
For the first time, all of the available information needed to identify the adults of all recognized species inhabiting South America has been compiled from a large number of individual taxonomic works written in six languages during the past two centuries.
In addition to the descriptions of the morphological features used to distinguish the species, the keys provide the known ranges listed by country and by states within Brazil, as well as the synonyms most likely to be encountered in the literature.
The publications cited can be found compiled in an extensive bibliography, informing the user where more additional information about each species can be located.
