; class Insecta, order Odonata)
Smallest of the three suborders of dragonflies, comprising insects which are superficially similar to the Anisoptera, but whose wings have narrow bases (a feature of Zygoptera). The larvae also show features possessed by both the other suborders. The Anisozygoptera flourished during the Mesozoic, when they replaced the ancestral dragonfly order Protanisoptera. Today there are only two, poorly known, living species, found in India and Japan. See also Epiophlebiidae.
