Zygoptera 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. 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 characteristics
commonly used to distinguish the species. This will show the user
of the identification keys in the volume the alternative names for
the anatomical structures most frequently encountered in the
literature. 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.
Most of the book is devoted to keys that facilitate
identification of both adults and those larvae which have already
been described. 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. Separate keys are provided to identify all larvae
that have been positively identified and described prior to early
2007. 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 with the species names andin the keys can be
found compiled in an extensive bibliography, informing the user
where more extensive species descriptions and additional
information about each species can be located. Although taxonomic
revisions are deliberately avoided, suggestions for additional
research and the opinions of experts concerning immanent taxonomic
changes are provided where appropriate.
To provide the user of the keys with maximum assistance in
making reliable identifications, the book is richly illustrated
with pen and ink drawings of thousands of individual morphological
structures arranged in 767 figures. It is certain that many
significant changes will occur in the systematics of South American
damselflies in the future, and this book is meant to provide the
impetus needed to accelerate the work of nomenclature and revision.
Meanwhile, it will provide a comprehensive overview of the South
American Zygoptera that has hitherto remained almost unobtainable
to most South American scientists because of the great difficulties
in obtaining the numerous publications from numerous countries in
which the original descriptions of species and taxonomic revisions
have appeared. It also provides student entomologists with a basic
text for learning what they need to know to work effectively with
the Zygoptera of South America and adjacent regions.
