Ebook "Encyclopedia of South American aquatic insects: Odonata - Zygoptera - Illustrated keys to known families, genera, and species in South America" was begun to provide keys to the aquatic insect species known from Brazil. The original goal was to include all genera known from South America and all species from Brazil, but for most groups, the scope was expanded to encompass all species in South America, and, in some cases, to include terrestrial species of orders that include both terrestrial and aquatic taxa.
