Classification & Phylogeny
- The modern order Odonata is divided into
two main suborders: Zygoptera (damselflies) and Epiprocta. Epiprocta is then further subdivided into two infraorders,
( true dragonflies) and the Anisozygoptera (a relic group with only two extant representative
species). extinct dragonflies belong to a taxonomic group known
Major Groups of the
Odonatoptera. extinct groups are signified by Ý.
- The Protoanisoptera, whose desendents are probably the Anisoptera,
are known from the Carboniferous and are characterized by dissimilar
fore and hind wings. These are large robust fast flying dragonflies.
- The Protozygoptera, whose desendents are the damselflies (Zygoptera),
are known from Permian deposits; in these the fore and hind wings
are a similar shape. They are small and slender insects, which
fly less rapidly than the anisopterans.
- The Anisozygoptera, a relict group represented by only two living
species, both found in remote streams in fare east Asia, and
they are listed as endangered species.
