Order Odonata

Abstract

Odonata is a cosmopolitan and ubiquitous order of insects, represented in most aquatic environments by approximately 6,000 species, of which more than 1,700 occur in the Neotropical region. It is considered a monophyletic group, but higher relationships within the order are not fully resolved yet. The larvae of only about 75% genera and 40% of the species are known, many larval descriptions are too brief or out of date, and the existing keys only involves certain regions or countries. Here, we present a glossary with morphological terms and a key to the families.
